Question

Explain the rule with example according to which electorns are filled in various energy levels​

Answer 1

Answer:

Hi. Hope i am able to clear your doubt

Explanation:

The electrons move around the nucleas in an atom . the electrons have a specified path which are callee shells.

tge electrons doesn't have a pattern that which electron will reside in which shell.

Answer 2

It was Bohr's model of atom which explains about different energy levels and discrete orbits of electron inside the atom.

The electronic configuration is that in first shell or energy level K the maximum number of electron present cannot be more than 2.

2n^2 is the formula for calculating electron were n is the number of shell.

For example In k shell 2×(1)^2=2×1=2

The maximum number of electron accommodated in the shell is 8.
