10. ELECTRON WKSHT
TAKE 2 MINUTES TO READ THE 8 FACTS GIVEN ON THE WORKSHEET

11. ELECTRON WKSHT (1)
Each electron has its own distinct amount of energy.
The electrons reside in the electron cloud.
The electron cloud is divided into energy levels (also known as shells). The lowest energy level is closest to the nucleus.

12. ELECTRON WKSHT (2)
Electrons are naturally in ground state (lowest energy state).
When a specific amount of energy is absorbed (gain), the electron moves to a higher energy state (excited state). Example – jumps from 2nd energy level to 3rd energy level.
The excited state is temporary. After a specific amount of energy is released (emitted), the electrons return to a lower energy state.

13. ELECTRON WKSHT (3)
Bright line spectrum is emitted when the electrons release energy and return to a lower energy state. In other words, light is emitted when electrons return from a higher energy state to a lower energy state.

14. ELECTRON WKSHT (4)
Electron Configuration represents the distribution of all electrons for an element.
The electron configuration shown on the periodic table is at ground state.
Adding the number shown in the electron configuration will give the number of electrons for an element. Example: = 11 electrons
