Question

which group or groups of atoms are the only atoms with forbitals?a) all atoms heavier than krypton (kr)b) all atoms heavier than barium (ba)c) all noble gasesd) lanthanides and actinidesquestion 2 (5 points)what name would be given to the ionic compound liclo₂?a) monolithium dichlorateb) lithium chloritec) lithium chlorine oxide

Explanation:

For the first question:

• Lanthanides and actinides are the only groups of atoms with \(f\) orbitals. Noble gases don't have only \(f\) orbitals. Atoms heavier than krypton or barium don't specifically refer to the groups with \(f\) orbitals.

For the second question:

• In naming ionic compounds, for \(LiClO_2\), \(Li\) is lithium. The polyatomic ion \(ClO_2^-\) is chlorite. So the name is lithium chlorite. "Monolithium dichlorate" is an incorrect naming as we don't use "mono -" for ionic compounds in this context. "Lithium chlorine oxide" is also an incorrect name for this compound.

Answer:

1. D. Lanthanides and actinides
2. B. Lithium chlorite
