Dear student,
 
Niels Bohr proposed the atomic model in 1912. He suggested that electrons move around the nucleus in specific orbits at a fixed distance from the nucleus in circular paths known as Orbits.
 
Electrons do not lose energy while moving in these orbits and thus, these orbits are called stationary or stable orbits.
 
The energy of the orbit nearest to the nucleus is the least and goes on increasing as the distance from the nucleus increases.
 
The arrangement of electrons around the nucleus in an atom can be explained as follows:
 
1. The first orbit closest to the nucleus is called the K orbit and can accommodate a maximum of 2 electrons.
2. The second orbits is called the L orbit and can accommodate a maximum of 8 electrons.
3. The third orbits is called M orbit and can accommodate a maximum of 18 electrons.   
4. The fourth is the outermost orbit called N orbit and can accommodate a maximum of 32 electrons.
 
The electrons are arranged in the order in these orbits. The electrons fill the next orbit only after filling the previous one.
.
