• A. $G{e}^{2+}<S{n}^{2+}<P{b}^{2+}$
• B. $P{b}^{4+}<S{n}^{4+}<G{e}^{4+}$
• C. $S{n}^{2+}<S{n}^{4+}$
• D. $P{b}^{4+}<P{b}^{2+}$

Answer 1

Answer: (A), (B), (C), (D)

Correct answer is (a) $G{e}^{2+}<S{n}^{2+}<P{b}^{2+}$ Correct answer is (b) $P{b}^{4+}<S{n}^{4+}<G{e}^{4+}$ Correct answer is (c) $S{n}^{2+}<S{n}^{4+}$ Correct answer is (d) $P{b}^{4+}<P{b}^{2+}$
