Is the bond order in superoxide ion more or less than in peroxide ion? Explain on the basis of MO theory.
The MO electronic configuration of superoxide ion 
is
Here 
The M.O. electronic configuration of peroxide ion 
is 
So, the bond order in superoxide ion is more than in peroxide ion.
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.
Out of Na and K, which will form a more stable ionic bond?
Which will have a greater lattice enthalpy: NaCl or MgO?
Is a covalent molecule always formed between two similar atoms?
Why sodium chloride is a solid whereas carbon tetrachloride is a liquid?
Why NaCl gives a white percipitate with AgNO3 solution but CCl4 does not?
