The electronic configurations of atoms of three elements A. B and C are (2, 8, 1), (2, 8, 6) and (2, 8, 18, 7) respectively.
Which option classifies the elements A. B and C as metals and non-metals correctly?
A -> Metal, B -> Non-Metal, C -> Non-Metal
A -> Metal, B -> Non-Metal, C -> Non-Metal
Metal : Loses electrons;to attain stable electronic configuration.
Non-Metal : Gains electrons to attain stable electronic configuration.
