Give an example in each of the following cases:(i) a divalent anion (valency 2)(ii) a trivalent cation (valency 3)

List out cations and anions separately as monovalent

Covalent character of an ionic compound is more when(i)     Polarisation power of cation is more(ii)    Polarisability of anion is more.(iii)   Charge on the anion is less(iv)    Size of cation is lessChoose the correct statements. (i) and (ii) only (i), (ii), (iii), (iv) (i), (ii) and (iv) only (i), (ii) and (iii) only

Which of the following is a polar covalent bond? Select ALL that apply

Which of these covalent structures does not have a viable structure?(Think about the valence of each atom).Group of answer choices
