Question

what are the rules to be followed for filling electrons in the orbit of an atom explain with example​

Answer 1

Answer:

This principle states that the electrons are added one by one to the various orbitals in order of their increasing energy starting with the orbital of lowest energy. ...

1s<2s<2p<3s<3p<4s<3d<3d<5s<5p<6s<4f<5d<6p<7s<5f<6d<7p……

In neutral isolated atom, the lower the value of (n + l) for an orbital, lower is its energy.

Answer 2

$\huge\bf{Answer:-}$

Rules of filling electrons in orbitals;

Important Rules for Filling Orbital:-

• This principle states that the electrons are added one by one to the various orbitals in order of their increasing energy starting with the orbital of lowest energy.

• 1s<2s<2p<3s<3p<4s<3d<3d<5s<5p<6s<4f<5d<6p<7s<5f<6d<7

• In neutral isolated atom, the lower the value of (n + l) for an orbital, lower is its energy.
