Answer:
When halogen elements react with group one metals they form halide salts.
Explanation:
The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their chemical properties are resemble greatly with each other. As we move down the group in periodic table size of halogens increases that's way fluorine is smaller in size as compared to other halogens elements. Their boiling points also increases down the group which changes their physical states. i.e fluorine is gas while iodine is solid.
When halogen elements react with group one metals they form halide salts.
Alkali metals have one valance electron and halogens needed one electron to complete the octet thus alkali metals loses one electron which is accepted by halogens atom and form ionic compound called halide salts.
For example:
2Na + Cl₂ → 2NaCl
2K + Cl₂ → 2KCl
2Rb + Cl₂ → 2RbCl
2Li + Cl₂ → 2LiCl
With bromine:
2Na + Br₂ → 2NaBr
2K + Br₂ → 2KBr
2Rb + Br₂ → 2RbBr
2Li + Br₂ → 2LiBr
With iodine:
2Na + I₂ → 2NaI
2K + I₂ → 2KBI
2Rb + I₂ → 2RbI
2Li + I₂ → 2LiI
Elements in the first row are filling their 1s orbitals. Since hydrogen is the first element, its electron configuration is 1s1 . It has only one electron in its valence shell. Valence electrons are the outermost electrons or electrons in the largest energy level.
Answer:
Yes? Sry I’m kinda confused
Explanation:
Sry if I’m wrong
Answer:
Electrons
Electric charge is carried by subatomic particles such as electrons and protons, which can be created and destroyed. For example, when particles are destroyed, equal numbers of positive and negative charges are destroyed, keeping the net amount of charge unchanged.
Answer:
Explanation:
The alkene reactions in general are addition or oxidation reactions. For the addition reaction, we have to take into account that some of them are marknonikov and other anti-markovnikov. Also for the addition reaction, we will have to take into account if we will have anti or syn products. In the oxidation reaction, we have to know the specifics for each reaction. If the reaction can go to the highest oxidation level, is the double bond is broken, etc.
Each reaction has its <u>specific characteristics</u> (see figures 1 and 2).
