Which one of the following alkaline earth metal carbonates is thermally most stable?
(a) MgCO3 (b) CaCO3 (c) SrCO3 (d) BaCO3

In a metallic bond, why positive ions are called kernels, not cations?
The kernel is an atom without its valence electrons that are weakly bonded; no electron belongs to one nucleus, valence electrons can move one kernel to another. So it is known as kernel, not cation (have valency).
