Electrons on Bohr model of atoms

1. Electrons are placed on Energy Levels from the one closest to the nucleus (1st energy level) outwards.

2. Each level can hold a certain amount of electrons

3. Once the maximum number of electrons the Energy level can hold is filled, the other electrons are sent to the next Energy level until all are placed in orbitals.

4. Electrons on outermost Energy Level are called VALENCE ELECTRONS.

​5. The maximum number of electrons on valence shell is 8 for any atom

​Examples

Since 13 protons it has 13 electrons

1st shell=2

​2nd shell=8

​3rd shell=3

Since 19 protons it has 13 electrons

1st shell=2

​2nd shell=8

​3rd shell=8

​4th shell= 1

​Since 4 protons it has 4 electrons

1st shell=2

​2nd shell=2

Multiple Choice
