Answer 1

Lewis electron dot symbol is a structure of a molecule that shows the bonding between atoms as well as lone pairs of electrons of atoms also. Valence electron: The electrons which are present in the outer most energy level are known as valance electron. This can be calculated by the group number of the element. Generally the group number is same as the valance electrons of any elements. The atomic number of Mg is 12 1s2, 2s2 2p 3s2 A Lewis dot structure is as follows: Mg: The atomic number of Sis 16 1s2, 2s22p6 382 3p4 A Lewis dot structure is as follows: The Lewis structure of H20 is as follows: S: First we calculate the total valance electron as follows: Valance electron = 1*2 (H) + 6*1(0) The Lewis structure of HF is as follows: =2+6 First we calculate the total valance electron as follows: =8 Valance electron = 1*1 (H) +9*1(F) =1+7 There are 4 bond electrons and reaming 8-4=4 electrons are present as bond pair as follows =8 There are 2 bond electrons and reaming 8-2=6 electrons are present as bond pair as follows H-F: The Lewis structure of H20 is as follows: HO
