Name the conditions for the formation of an ionic bond between two atoms.
What is crystal lattice?
What is electrovalency?
What bond is present in MgCl2 molecules?
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.
