<em>
Cation</em>
When naming a chemical compound, <u>the cation</u> is written first before anything else.
A typical ionic compound consists of two components - the cation and the anion. While the <u>cation is positively charged in ion</u>, <u>the anion is negatively charged. </u>The cation of a typical ionic compound is named first before the anion and the name often carries that of the element that composes it.
The name of the element that makes up the anion is modified by removing the last few characters ending the name and replacing it with the suffix 'ide'. For example, NaCl is named sodium chloride.
Answer:
second energy level
Explanation:
Valence electrons are those electrons which are present in outer most orbital of the atom.
This can be easily found through the electronic configuration of atom.
Electronic configuration of F:
F₉ = 1s² 2s² 2p⁵
We can see that the valence electrons are present in second energy level of F atom.
There are seven valence electrons of fluorine.
It is called halogens.
Halogens are very reactive these elements can not be found free in nature. Their boiling points also increases down the group which changes their physical states. i.e fluorine is gas while iodine is solid.
Fluorine:
1. it is yellow in color.
2. it is flammable gas.
3. it is highly corrosive.
4. fluorine has pungent smell.
5. its reactions with all other elements are very vigorous except neon, oxygen, krypton and helium.
I'm pretty sure it's B)constructive
