Question

Sodium having atomic number 11is ready to ______ electron to attain the nearest noble gas electronic configuration​

Answer 1

Answer:

Explanation:The number of electrons that an atom of an element loses or gains to form an electrovalent bond is called its Electrovalency. The atomic number of Sodium is 11 and its electronic configuration is 2, 8, 1. It has one electron excess to the nearest stable electronic configuration of a noble gas - Neon.

Answer 2

We know that :-

Electronic configuration of Sodium :-

= 2,8,1

The nearest noble gas to Sodium

is Neon.

Electronic configuration of Neon :-

= 2,8

From above we can infer that Sodium has one more electron than Neon. Thus, in order to attain the electronic configuration of Neon, Sodium has to lose one excess electron which it has.

Hence :-

Sodium having electronic configuration 11 is ready to lose one electron to attain the nearest noble gas electronic configuration.

Some Extra Information:-

The electronic configuration of some elements are :-

• Hydrogen [H] = 1

• Carbon [C] = 2,4

• Nitrogen [N] = 2,5

• Oxygen [O] = 2,6

• Aluminium [Al] = 2,8,3

• Potassium [K] = 2,8,8,1

• Calcium [Ca] = 2,8,8,2
