In general, the ionic radius increases on moving from top to bottom in group and decreases on Inoving from left to right in period So, the correct order is

0.98 \overset{˚}{A} N a^{+} > 0.68 \overset{˚}{A} L i^{+} > 0.65 \overset{˚}{A} M g^{2 +} > 0.62 \overset{˚}{A} B e^{2 +}

Q. The set representing the correct order of ionic radius is

$L i^{+} > B e^{2 +} > N a^{+} > M g^{2 +}$

$N a^{+} > L i^{+} > M g^{2 +} > B e^{2 +}$

$L i^{+} > N a^{+} > M g^{2 +} > B e^{2 +}$

$M g^{2 +} > B e^{2 +} > L i^{+} > N a^{+}$

In general, the ionic radius increases on moving from top to bottom in group and decreases on Inoving from left to right in period So, the correct order is

$0.98 \overset{˚}{A} N a^{+} > 0.68 \overset{˚}{A} L i^{+} > 0.65 \overset{˚}{A} M g^{2 +} > 0.62 \overset{˚}{A} B e^{2 +}$

Q. The set representing the correct order of ionic radius is

Li+>Be2+>Na+>Mg2+

Na+>Li+>Mg2+>Be2+

Li+>Na+>Mg2+>Be2+

Mg2+>Be2+>Li+>Na+
