Question

The correct arrangement of increasing order of atomic radii among Na, K, Mg, Rb is (A) Mg< K< Na< Rb (B) Mg< Na< K< Rb (C) Mg< Na< Rb< K (D) Na< K< Rb< Mg

Tardigrade Admin · Accepted Answer

Atomic radii decrease along the period and increase down the group. Hence the order is: Mg< Na< K< Rb

Q. The correct arrangement of increasing order of atomic radii among Na, K, Mg, Rb is

$M g < K < N a < R b$

$M g < N a < K < R b$

$M g < N a < R b < K$

$N a < K < R b < M g$

Atomic radii decrease along the period and increase down the group. Hence the order is :
$M g < N a < K < R b$

Q. The correct arrangement of increasing order of atomic radii among Na, K, Mg, Rb is

Mg<K<Na<Rb

Mg<Na<K<Rb

Mg<Na<Rb<K

Na<K<Rb<Mg

Atomic radii decrease along the period and increase down the group. Hence the order is : Mg<Na<K<Rb

$M g < K < N a < R b$

$M g < N a < K < R b$

$M g < N a < R b < K$

$N a < K < R b < M g$

Atomic radii decrease along the period and increase down the group. Hence the order is :
$M g < N a < K < R b$
