What are the different types of hybridisation in s and p atomic orbitals?
These are of three types:
(i) sp type (Linear)
(ii) sp2 type (Trigonal)
(ii) sp3 type (Tetrahedral).
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?
