Total energy of an electron in hydrogen atoms above 0 eV leads to

Correct answer: (A) ionisation of the atom. When energy of electron in a hydrogen atom goes above 0 eV then it leaves the atom. Hence hydrogen atom becomes ionised.

Q144 / 180 · AIIMS 2015 · Physics

Total energy of an electron in hydrogen atoms above $0 \mathrm{eV}$ leads to

Correct answer
A
ionisation of the atom
B
accelerate the atom
C
send the atom in higher excited state
D
none of these

Solution

When energy of electron in a hydrogen atom goes above $0 \mathrm{eV}$ then it leaves the atom. Hence hydrogen atom becomes ionised.

Hence, the correct answer is option: 'A'.
