Question

Nucleus of an atom has 5 protons,6 neutrons.What is the atomic number, mass number,electronic configuration of yhe atoms

Answer 1

Given:

Number of protons = 5

Number of Neutrons = 6

To find:

Atomic number =?

Mass number = ?

Electronic configuration = ?

Formula to be used:

Mass number = No. of protons + No. of neutrons

Calculation:

Atomic number

• The number of protons is equal to the atomic number of the element.
• As the nucleus of atoms is composed of 5 protons, the atomic number of the element is identified as 5.

Mass number

• To calculate the mass number of the element, the following formula must be used:
• Mass number = No. of protons + No. of neutrons = 5+6= 11
• Thus the mass number of the element is identified as 11.

Electronic configuration

• The electronic configuration is written based upon the atomic number of the element.
• As the atomic number of the element is identified as 5, its electronic configuration will be $1s^22s^22p^1$.
