Question

The magnetic moment (m_orb) of a revolving electron around the nucleus varies with the principal quantum number (n) as ______.

विकल्प

• m_orb ∝ n²

• `"m"_"orb" ∝ 1/"n"^2`

• `"m"_"orb" ∝ 1/"n"`

• m_orb ∝ n

Answer 1

The magnetic moment (m_orb) of a revolving electron around the nucleus varies with the principal quantum number (n) as m_orb ∝ n.

Explanation:

The magnetic moment of a revolving electron in an orbit around the nucleus is given by

M_orb = `("neh")/(4pi"m"_"e")`

⇒ m_orb ∝ n
