The periodic table of chemical elements in the third year of junior high school has no self compilat

1" Please Li Najia visit Ruse.

2" is comparable to being tired of covering words (this teacher said that it is so prepared!) I'm too tired to cover the words) 3" touched the aluminum (female) good news her.

4. The carbon returnees move westward.

5. The egg is closed.

6" Father chlorine (female) embroidered love.

7. Harm Naike to move first.

Recommend this. In fact, there are only 20 to memorize in the third year of junior high school, and the back is also memorized.

You just carry 1h2he3li like this, that is, the numbers are with the elements together.

Every set of 5, the back is OK.

The formulas of the periodic table are as follows:Periodic table formulas by periodFirst Cycle:Hydrogen, helium – violation.

Second Cycle:Lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon - carp skin holds carbon eggs to raise blessing milk.

Third Cycle:Sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon - that beautiful Guilin has green teeth.

Fourth Cycle:Potassium, calcium, scandium, titanium, vanadium, chromium, manganese - the marriage reform Kang is too fierce.

Iron, cobalt, nickel, copper, zinc, gallium, germanium - Tiegu pinched the newlyweds.

Arsenic, selenium, bromine, krypton - angry, shock.

Fifth Cycle:Rubidium, strontium, yttrium, zirconium, niobium – so to you.

Molybdenum, technetium, ruthenium – unbelievable.

Rhodium, palladium, silver, cadmium, indium, tin, antimony - the old silver brother Yinxi embankment.

Tellurium, iodine, xenon - place immortals.

Sixth Cycle:Caesium, barium, lanthanum, hafnium - (color) color shell (shell) blue (color) river.

Tantalum, tungsten, rhenium, osmium – but (see) the crow (leads) the goose.

Iridium, platinum, gold, mercury, stone, lead—a white towel for it to pull.

Bismuth, polonium, astatine, radon - they will not love winter.

Seventh Cycle:Francium, radium, actinium - lightning protection.

Periodic table formulas by family:Hydrogen, lithium, sodium, potassium, rubidium, cesium, francium - please Li Na join the private interview.

Beryllium magnesium trapped calcium, strontium, barium, radium - comparable to Gates was thundered.

Boron, aluminum, gallium, indium, thallium - touching the girl to marry him.

Carbon, silicon, germanium, tin, lead—the westward migration of returnees.

Nitrogen, phosphorus, arsenic, trapped antimony, bismuth - the egg is close to the body.

Oxysulfur, selenium, tellurium, polonium - raising cattle west hooves.

Chlorochlorobromoiodine astatine - father and daughter embroider some love.

Helium, neon, argon, krypton, xenon, radon, - harm to the first move.

Periodic table of chemical elements.

Iridium, platinum, gold, mercury, stone, lead—a white towel for it to pull.

Bismuth, polonium, astatine, radon - they will not love winter.

The seventh cycle: francium, radium, actinium, lightning protection!

The above is the formulas of the periodic table of chemical elements that I have compiled in the third year of high school, and I hope it will be helpful to the students' learning.

The periodic table of chemical elements about the third year of the first three is as follows:

First, the periodic table of chemical elements is smooth and easy to say

Qing harm Li Pipeng, Tan Danyang pay milk (hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxyfluorine, neon). The beauty of Guilin, the dew of the marriage (sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chloride, argon, potassium, calcium deficit). Anti-Taiwan counter-revolution, providing new problems (scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc).

The fake is ashamed, and can be engaged in wanton (gallium, germanium, arsenic, bromine, kryptonium, rubidium, strontium, yttrium, zirconium). Your mother has tuberculosis, and the Eight Tone Pavilion is hidden (niobium, molybdenum, technetium, ruthenium, rhodium, palladium, silver, cadmium, indium tin).

For the younger brother to point out the fairy color, Belan is a common girl (antimony tellurium, iodine, xenon, cesium, barium, lanthanum, cerium, neodymium).

2. Memorize formulas for junior high school chemistry knowledge points

1. The periodic table of chemical elements with valency in junior high school slips smoothly

potassium, sodium, silver, hydrogen positive bivalent, calcium, magnesium, barium, zinc; Aluminum is positive trioxan minus di, chlorine minus monovalent is the most common; Sulfur has negative two positive four six, positive two positive three iron variable; is one or two copper town empty two four carbon, the zero price of the element will never change; Other elements have valence, which is calculated by dying first and then living. The valence should be accurate, monovalent potassium, sodium, silver chloride, divalent oxygen, calcium barium, magnesium, zinc, trisilicon, tetraaluminum, and pentavalent phosphorus; It is not difficult to talk about price change, and the two, three, iron, two, four, and four carbon are complete.

Copper-mercury bivalent is the most common; The atomic group should not be divided, monovalent ammonium hydroxide, divalent sulfate carbonate, and trivalent phosphate. Monovalent fluorochlorobromo, iodide, hydrochloro, potassium, sodium, silver, barium oxide, calcium, magnesium, zinc, aluminum, trisilicon, and tetra are all fixed. It should be noted that the price of chlorine and nitrogen should be paid attention to, one or two copper, mercury, one or three gold, two tetracarbon, lead, two three iron, two tetrahexasulfur, and three or five phosphorus.

chlorochlorobromoiodine negative monovalent; N-monohydrogen silver with potassium sodium.

The minus two of oxygen should be remembered first; n-2 magnesium, calcium, barium and zinc, n-3 aluminum-s-tetrasilicon; Let's put the price change down. All metals are regular; One or two coppers come two or three irons. Manganese is 24 and 67; Carbon 24 to keep in mind.

non-metallic negative main is uneven; Chlorine minus one positive one five seven. Nitrogen and phosphorus minus three and plus five; Different phosphorus three nitrogen two four, sulfur has negative two positive four six; It will be cooked when you use it while memorizing it.

2. Experimental procedure for reducing copper oxide with CO

One pass, two points, three extinguishes, four stops, five processing. "Pass"Hydrogen first,"Two points"After lighting the alcohol lamp for heating:"Three extinguished"After the experiment, the alcohol lamp is extinguished"Four stops"Wait until room temperature before stopping the hydrogen supply"Five. Processing"Exhaust gas is treated to prevent CO from polluting the environment.

The periodic table of the three chemical elements is as follows:

Cycle 1: Hydrogen helium attack.

The second cycle: lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, carp skin, carbon, eggs, and milk.

The third cycle: sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon -- the beautiful Guilin has green teeth (that beautiful ghost shows green teeth).

Fourth Cycle: Potassium, Calcium Scandium, Titanium, Vanadium, Chromium, Manganese, Marriage and Reform Kangtai Counter-Revolution.

Iron, cobalt, nickel, copper, zinc, gallium, germanium - Tiegu pinched the newlyweds.

Arselenium, bromide, krypton, angry shock.

Fifth cycle: Rubidium, Strontium, Yttrium, Zirconium, Niobium So tell you.

Molybdenum, technetium, ruthenium – unbelievable.

Rhodium, palladium, silver, cadmium, indium, tin, antimony - the old silver brother Yinxi embankment.

Tellurium, iodine, xenon - place immortals.

Sixth cycle: cesium, barium, lanthanum, hafnium, colored shells, blue rivers.

Tantalum, tungsten, rhenium, osmium – but (see) the crow (leads) the goose.

Iridium, platinum, gold, mercury, stone, lead—a white towel for it to pull.

Bismuth, polonium, astatine, radon - they will not love winter.

The seventh cycle: francium, radium, actinium -- it's very simple, it's --- lightning protection!

The periodic table of chemical elements in junior high school slips smoothly as follows:

Cycle 1: Hydrogen helium attack. The second cycle: lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, carp skin, carbon, eggs, and milk. Third Cycle:

Sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon - that beautiful Guilin has green teeth. Fourth cycle: potassium, calcium, scandium, titanium, vanadium, chromium, manganese, --- marrying and reforming, Kang is too anti-cute; Iron, cobalt, nickel, copper, zinc, gallium, germanium - Tiegu pinched the newlyweds. Arselenium, bromide, krypton, angry shock.

Fifth cycle: Rubidium, Strontium, Yttrium, Zirconium, Niobium So tell you. Molybdenum, technetium, ruthenium – unbelievable. Rhodium, palladium, silver, cadmium, indium, tin, antimony - the old silver brother Yinxi embankment. Tellurium, iodine, xenon - place immortals.

Sixth cycle: cesium, barium, lanthanum, hafnium, colored shells, blue rivers. Tantalum, tungsten, rhenium, osmium – but (see) the crow (leads) the goose. Iridium platinum mercury pin lead --- a white towel for it to pull; Bismuth, polonium, astatine, radon - they will not love winter. The seventh cycle: francium, radium, actinium, lightning protection!

The periodic table of elements is a list of chemical elements sorted by atomic weight, from smallest to largest. The list is generally rectangular in shape, with spaces in the period of some elements, so that elements with similar characteristics are grouped in the same group, such as alkali metal elements, alkaline earth metals, halogen elements, noble gases, non-metals, transition elements, etc.

This makes the orange in the periodic table form an elemental division and is divided into seven main groups, seven secondary groups, families, and 0 groups. Because of its ability to accurately determine the properties of various elements and the relationships between them, the periodic table is widely used in chemistry and other scientific fields as a useful framework for analyzing chemical behavior.
