Question

Which is the correct Lewis structure for fluorine, which is a group 7A element?

Answer 1

The question says,'which is the correct Lewis structure for fluorine, which is a group 7A element. Lewis structure is used to represent the covalent bonding of molecules. Flourine has seven electron in its outermost shell, so the Lewis structure of flourine will have 3 lone pair of dots and a single dot. Each dot represent an electron.

Answer 2

Explanation :

Lewis-dot structure : It is defined as the representation which shows the valence electrons present in an element. The electrons are represented as dots in the structures.

The given element is, fluorine which is a group 7A element.

The atomic number of fluorine is 17 and fluorine has '7' valence electrons.

The dots represent the number of valence electrons.

The Lewis-dot structure of fluorine is shown below.
