Question

Lines in an atomic emission spectrum of an element are due to (A) excitation of electrons from lower energy levels to higher levels (B) energy of electrons (C) excited electrons dropping from higher levels to lower energy levels (D) nuclear charges

Tardigrade Admin · Accepted Answer

Δ E emitted is always for En2-En 1 where n2>n1 i.e., lines in an atomic emission spectrum of an element occur when an excited electron drops from higher energy to lower energy level.

Q. Lines in an atomic emission spectrum of an element are due to

excitation of electrons from lower energy levels to higher levels

energy of electrons

excited electrons dropping from higher levels to lower energy levels

nuclear charges

$Δ E$ emitted is always for $E_{n_{2}} - E_{n 1}$ where $n_{2} > n_{1}$ i.e., lines in an atomic emission spectrum of an element occur when an excited electron drops from higher energy to lower energy level.
