Draw the lewis structure for bef2 in the box at the right, including lone pairs.
Lewis-dot structure: It shows the bonding between the atoms of a molecule and the unpaired electrons present in the molecule.
The given molecule is, Be F2
Beryllium has ‘2’ valence electrons and fluorine has ‘7’ valence electrons. Beryllium is the central atom and fluorine is the terminal atom.
Total number valence electrons in Be F2 = 2 + 2(7) = 16
According to the Lewis-dot structure, there are ‘4’ number of bonding electrons and 12 number of non-bonding electrons (lone-pair).
Lewis structure of bef2: The Lewis-dot structure is shown below.
