less electrons are present in antibonding molecular orbitals.
Which one of the two O+2 and O-2 has higher bond order and why?
less electrons are present in antibonding molecular orbitals.
Two elements A and B have the electronic configuration as:
A = 1s22s22p63s2 and B = 1s22s22p5
Write the empirical formula of the substance containing A and B.
What type of bonding would you expect between:
(i) a metal and a non-metal
(ii) a non-metal and another non-metal?
Give reasons in one or two sentences for the observation that in their compounds non-metals form anions and not cations.
