As per Lother-Meyer's curve, the atomic volume of Cs is maximum among s-block elements. But atomic masses increases more rapidly than atomic volume, hence density increases along the group

Q. Increasing order of density is

$L i < K < N a < R b < C s$

$L i < N a < K < R b < C s$

$L i < N a < K < C s < R b$

$K < L i < N a < R b < C s$

As per Lother-Meyer's curve, the atomic volume of $C s$ is maximum among s-block elements. But atomic masses increases more rapidly than atomic volume, hence density increases along the group

Q. Increasing order of density is

Li<K<Na<Rb<Cs

Li<Na<K<Rb<Cs

Li<Na<K<Cs<Rb
