Concept explainers
(a)
Interpretation:
The name, empirical formula and character (covalent or ionic) of given compound should be identified.
Concept introduction:
A molecule is neutral group of two or more atoms joined together by
Ionic compound is a composed of ions held together by electrostatic forces called as ionic bond. The compound is neutral, it is of consists positively charged ions called cations and negatively charged ions called anions.
Compounds of metals with nonmetals are usually called as ionic, nonmetal-nonmetal compounds are usually molecular.

Chemistry: Atoms First
- 3. The skeleton of chloromethane is __________________ The central carbon atom is bonded to each of the other atoms by a shared electron pair (represented by a straight line, ___) giving Now, each hydrogen has two electrons and the carbon atom has eight. However, chlorine must be provided with unshared electrons (represented by pairs of dots, ) to complete its octet, thusarrow_forwardWhich of the following atoms would be expected to form negative ions in binary ionic compounds and which would be expected to form positive ions: P, I, Mg, Cl, In, Cs, O, Pb, Co?arrow_forwardWhich of the following atoms would be expected to form negative ions in binary ionic compounds and which would be expected to form positive ions: Br, Ca, Na, N, F, Al, Sn, S, Cd?arrow_forward
- 7.74 In a lattice, a positive ion is often surrounded by eight negative ions. We might reason, therefore, that the lattice energy should be related to eight times the potential of interaction between these oppositely charged particles. Why is this reasoning too simpler?arrow_forwardWhat aspect of the following Lewis structure indicates that the concept of coordinate covalency is needed to explain the bonding in the molecule?arrow_forwardhy is there an octet rule (and what does actet mean) in writing Lewis structures?arrow_forward
