Magnetic moment of X 3 + ion of 3 d series is 2 6 B M . What is the atomic number of X ?

Magnetic moment n ( n + 2 ) = 2 6 ⇒ n ( n + 2 ) = 24 ⇒ n = 4 ⇒ M n 3 + has 4 unpaired electrons. atomic number of X = 25

Magnetic moment of $X^{3 +}$ ion of $3 d$ series is $2 \sqrt{6} B M$ . What is the atomic number of $X$ ?

Options:

Answer:

Solution:

Magnetic moment $\sqrt{n (n + 2)} = 2 \sqrt{6} \Rightarrow n (n + 2) = 24 \Rightarrow n = 4$

$\Rightarrow M n^{3 +}$ has $4$ unpaired electrons.
atomic number of $X = 25$
