Question

In an orbital the electron pair is represented as $\upharpoonleft \downharpoonright$.

• A. True
• B. False

Answer 1

The correct option is A True

Spin quantum number $\left(m_s\right)$ refers to the possible orientations of an electron in an orbital. One is clockwise spin of the electron $(+\frac{1}{2})$ which is represented by $\upharpoonleft$ and other is anti-clock wise spin $(-\frac{1}{2})$ which is represented by $\downharpoonright$.

So, the correct representation of an electron pair in an orbital is $\upharpoonleft \downharpoonright$.
