Question

State the maximum number of electrons that can be present in the first, second and third electron orbits of atoms.​

Answer 1

Answer:

1st orbit contains 2 electrons

2nd orbit contains 8 electrons

3rd orbit contains 18 electrons

Explanation:

the maximum number of electrons that can be presented tn an orbit is represenyed by

2n²

Answer 2

Answer:

2,8,8

Explanation:

the nucleus has protons+ve charge and neutrons are neutral.

in first orbit or k shell maximum number of electrons can be 2.

in second orbit or L shell maximum number of electrons can be 8.

in third orbit or M shell maximum number of electrons can be 18.

in fourth shell or N shell maximum number of electrons can be 32.

and as the number of shell increases more numbers of electrons add up by using the formula 2n^2.
