Cognitive history

Historical origins. The origin of the idea of elements is very early, the ancient Babylonians and the ancient Egyptians once regarded water (and later air and earth) as the main elements of the world, forming the theory of the three elements. The ancient Indians had four major doctrines, and the ancient Chinese had the Five Elements Doctrine.

The doctrine of the elements, that is, the doctrine that the elements are the simplest constituent parts of all real objects in nature, has been produced since time immemorial. However, in ancient times, the modern notion of elements as a concrete form of matter did not exist.

Whether in the ancient philosophy of our country, or in the ancient philosophy of India or the West, the element is regarded as an abstract, a manifestation of the primitive spirit, or the basic nature of matter.

Ancient Greek natural philosophy put forward the famous theory of the four elements. This was not created by Greek philosophers, and the theory of the four elements existed in the traditional folk beliefs of ancient Greece, but was not (relatively speaking) supported by a solid theoretical system. The philosophers of ancient Greece "borrowed" the concepts of these elements as essence.

Periodic table of chemical elements.

is a list of chemical elements sorted from smallest to largest according to their atomic number. The list is generally rectangular in shape, with spaces in the period of some elements, so that elements with similar characteristics are grouped into the same family, such as alkali metal elements, alkaline earth metals, and halogen group elements.

Noble gases, etc.

First Cycle: Hydrogen Helium - Invasion.

The second cycle: lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon -- carp skin holding carbon, eggs and milk The third cycle: sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon -- the beautiful Guilin has green teeth (the beautiful ghost shows green teeth).

Fourth cycle: potassium, calcium, scandium, titanium, vanadium, chromium, manganese -- marrying Kangtai counter-revolutionary, iron, cobalt, nickel, copper, zinc, gallium, germanium -- iron, pinching, arsenic, selenium, bromine, krypton -- anger, shock.

Fifth cycle: rubidium, strontium, yttrium, zirconium, niobium -- so tell you molybdenum, technetium, ruthenium -- unbelievable.

Rhodium Yinhao, Palladium, Silver, Cadmium, Indium, Tin, Antimony--Laojiao, Yinge, Tellurium, Iodine, Xenon, Iodine, Xenon, Location, Immortals.

Sixth cycle: cesium, barium, lanthanum, hafnium, color, shell, blue, tantalum, tungsten, rhenium, osmium -- but (see) black (crow) (lead) to the stove, to Changxing, goose, iridium, platinum, mercury, stone, lead, and a white towel for it to lead bismuth, polonium, astatine, radon, and will not love winter (day).

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

H (hydrogen), Li (lithium), BE (beryllium), B (boron), C (carbon), N (nitrogen), O (oxygen), F (fluorine), Na (sodium), mg (magnesium), Al (aluminum), Si (silicon), P (phosphorus). S (sulphur), Cl (chlorine), K (potassium), Ca (calcium), Fe (iron), Cu (copper), Zn (zinc), I (iodine), BR (bromine), Ag (silver), Au (gold), Pb (lead), Sn (tin).

Chemical elements refer to more than 100 basic metallic and non-metallic substances in nature, which are composed of only one kind of atom, and each nucleon in its atom has the same number of protons, which cannot be decomposed by ordinary chemical methods, and can constitute all substances.

Classify. 1. Classification of elements: metal elements: next to "thium", except for mercury, non-metallic and halogen elements: "cyan", "stone" and "gas" indicate the state of their elemental existence in the usual state, and rare gas elements: "envy gas".

2. Writing: the principle of one large and two small: fe, cu, mg, cl, h, etc.

3. Significance: Represents an element (kind): represents an atom (particle) of this element:( knows an element, and can also find out the relative atomic mass of the element).
