Question

write are the rules for writing number of electrons in different energy level​

Answer 1

Answer

The following rules are followed for writing the number of electrons in different energy levels or shells:

(i) The maximum number of electrons present in a shell is given by the formula 2n2, where ‘n’ is the orbit number or energy level index, 1, 2, 3 ...

Explanation:

Hey friend,

Here's your answer,

The maximum number of electrons which can be accommodated in any energy level or shell was given by Bohr and Bury.

According to Bohr-Bury scheme :

1. The maximum number of electrons which can be accommodated in any energy level of the atom is given by 2n2 rule (where n is the number of that energy level).

2. The outermost shell of an atom cannot accommodate more than 8 electrons, even if it has the capacity to accommodate more electrons.

3. Electrons in an atom do not occupy a new shell unless all the inner shells are completely filled with electrons.

Answer 2

Answer:

1. the maximum no. of electron present in shells given by the formula 2n².

2.the outermost shells of an atom cannot accomodate more than 8 electrons,even of it has capacity to accomodaye mor electrons.

3. electron on an atom occupy a new shell unless all the shells are completely filled with electrons.
