Question

Sum of spin of all the electron in element having atomic number 14​

Answer 1

Answer:

sum of spin of all the electron in element having atomic no 14(silicon), is 1.

Answer 2

The sum of spin of all the electrons in an element having atomic number 14 is 1.

Given,

Element's atomic number= 14

To Find,

The sum of spin of all the electrons in this element.

Solution,

Since, it is given that the element has an atomic number= 14,

Therefore, this element is Silicon.

Atomic configuration of Si $= 1s^{2} 2s^{2} 2p^{6}3s^{2} 3p^{2}$

We know that the total spin of an element 's'= (Number of unpaired electrons) x (Spin of each electron)

In the above configuration, the Number of unpaired electrons= 2 and the spin of each electron= 1/2

Therefore, the total spin of all the electrons

                                                                     $= 2 * \frac{1}{2}$ = 1

Hence, the sum of all the electrons in an element having atomic number 14 is 1.
