Question

The valency of flourin is 1 what is the valence electron​

Answer 1

Fluorine, with a valency of 1, has seven valence electrons in its outer shell and tends to form a fluoride ion by gaining one electron.

Step-by-step explanation:

The valency of fluorine is 1, which indicates its ability to form one bond with another atom when participating in chemical reactions. Fluorine is a Group 7A element and has seven valence electrons. These are the electrons that are found in the outermost electron shell of an atom and are involved in the formation of chemical bonds.

The electron configuration for fluorine is 2s²2p⁵, which shows that these seven valence electrons are located in the second energy level of the atom. A fluorine atom tends to gain one more electron to achieve a stable electronic arrangement similar to that of a noble gas, leading to the formation of a fluoride ion (F⁻) with a full valent shell.

Answer 2

Fluorine has 7 valence electrons and would need another one to have a full outer valence electrons.
