There are regularities at all, but only partially, and the iron mentioned on the first floor above belongs to the special.
For example, halogens end with -ine.
Most metal elements end in sium, cium, mium, ium, I found two special ones when I was back, aluminum and platinum ended in num, and reminded the owner that fluorine is fluorine, not flourine, a mistake made by many of my classmates.
In the compound, the metal element is written in front, and the non-metallic element ends in the IDE after the metal element.
Such as: oxygen oxide, carbon carbide, nitrogen nitride, fluorine fluoride, chlorine chloride, bromine, bromide iodine, iodide phosphorus, phosphide, sulfur, sulfide
As for the Latin name, it is like this:
When a metal element shows a lower valence state and a more ** state, its Latin name is different.
For example, when iron +2 valence, ferrous +3 valence, ferric
iron(ii) iron(iii) – This is the English way of writing and uses Roman numerals to indicate valence.
Cobalt +2 cobaltous +3 cobaltic
Copper +1 cuprous +2 cupric
Tin +2 stannous +4 stannic
Gold +1 aurous +3 auric
Lead +2 plumbous +4 plumbic
The above is used to write the chemical formula.
for example:fecl2/ferrous chloride/
iron(ii) chloride
Hold the Lord and listen to what others have to say.

Some English names for chemical elements have been around for a long time, such as iron, silver, and gold, most of which are based on Latin variations, often with the suffix -ium.
Chinese chemical elements have a smooth memory method, such as lanthanide elements: male masters and female bodhisattvas are fried and suddenly lost all the way (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium), English seems to have no good memory methods, usually need to accumulate more. You can consult reference books such as Chinese-English dictionaries, or look at English chemistry textbooks used in Hong Kong and other countries.

Most English names are related to element symbols, with the exception of common things.
There is no rule, carbon dioxide is carbon dioxide, and everything else is said to be carbon dioxide. Ferric chloride is iron, chloride. Simply put it together.
The name, just write the symbol, really ask what you are, just write the English name, such as iron, just write iron.

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, palladium, silver, cadmium, indium, tin, antimony, --Laojiao, Yinge, Tellurium, iodine, xenon, --Location immortal.
Sixth cycle: cesium, barium, lanthanum, hafnium--color), color shell (shell), blue (color), river tantalum, tungsten, rhenium, osmium -- but (see) black (crow) (lead) goose iridium, platinum, gold, mercury, stone, lead, -- a white towel for it to hold bismuth, polonium, astatine, radon -- will not love winter (day).
The seventh cycle: francium, radium, actinium -- it's very simple, it's --- lightning protection!

organic chemistry.
organic: Adjective, organic, simple to memorize according to pronunciation.
chemistry: noun, chemistry, is a must-remember vocabulary in junior high school.
Together, these two words are organic chemistry!
It's really not possible to copy dozens of times, form a finger memory, and you can memorize it.

I think the best way to enter English is to memorize it through phonetic transcription. First of all, you need to know how to pronounce the English name, and then you can remember it better. Also, I think you can use associative mnemonics, when you know a certain level of organic chemistry, I think you should remember her English name.

Practice makes perfect. I had a hard time memorizing it at the time, but after reading more and more, I became familiar with it, and I first learned the English number. English is a great help for chemistry, because most of them are abbreviations or characters in English, so it shouldn't be a problem to learn English well and work harder.

My college major is pharmacy, what does this mean, it means that I can't do without organic chemistry, organic chemistry in college is different from high school, I need to read foreign languages more, at first I was very uncomfortable, because I couldn't understand it, and then I wrote the English of the functional group into a small card and memorized it every day.

In fact, these things are regular, for example, metals are generally suffix ium, and non-metals are generally suffix ine. It is even more similar to the main family, and it is important to summarize the method by yourself. No matter what you learn, it is important to memorize the summary method, so that you can get twice the result with half the effort.

There are thousands of organic compounds, and there are thousands of corresponding names, and it is far from enough to rely on a few rules in books, because English is different from Chinese, it is a backward language, and the words that have not been memorized will not be not, and cannot be speculated. Here are some easy ways to memorize. A meth eth prop but, but pent hexhex hept hept non non dec single (1) mono double bi 2di tri 4 tetr 5 pent 6 hex 7 hept 8 oct 9 non 10dec

It's a headache when I talk about this.,It's because I don't like to memorize things.,I chose science.,But in the end, I can't escape such a curse.。 Because I am not good at memorization, I study hard, read aloud, and copy over and over again in line with the learning attitude of stupid birds flying first, and I always feel that I can't remember, but I remember inexplicably when I take the exam in the end. I think it's still feasible to read it out loud and silently transcribe this memory a few times.
