Solution
Lewis dot structure
A Lewis Structure is a very simplified representation of the valence shell electrons in a molecule. Electrons are shown as "dots" or for bonding electrons as a line between the two atoms.
The goal is to obtain the "best" electron configuration, i.e. the octet rule and formal charges need to be satisfied.
Example
The Lewis dot structure of is as follows:
Beryllium is bonded with two fluorine atoms by single bonds.
Lone pairs of electrons are present on both fluorine atoms and the structure is linear.
