Question

Circle the appropriate word to complete each of the following statements. Electrons and protons (attract/repel) each other. As an electron gets closer to the nucleus, the (attraction/repulsion) to the nucleus gets (stronger/weaker). For an electron to move from an energy level close to the nucleus to an energy level far from the nucleus, it would need to (gain/lose) energy. For an electron to move from an energy level far from the nucleus to an energy level close to the nucleus, it would need to (gain/lose) energy.

Explanation / Answer

a) electron- -ve charge , proton -+ve charge ,hence, attract

b) attraction,stronger as nucleus has proton + neutrons ,so net +ve charge

c) lose as Kinetic energy will decrease

d) gain as Kinetic energy will increase
