Answer

Explanation:

Step1: Bohr model concept

Bohr's model is called a planetary model because electrons orbit the nucleus like planets orbit the sun.

Step2: Electron - energy relationship

Electrons in the same atom differ in their energy levels and distances from the nucleus.

Step3: Electron capacity of level

The fourth energy level can hold 32 electrons. The formula to calculate the number of electrons in an energy level is (2n^{2}), where (n = 4), so (2\times4^{2}=2\times16 = 32).

Step4: Electron energy change

An electron must absorb energy to jump from a lower energy level to a higher one and release energy to fall back.

Step5: Electron energy release

For an electron to fall from the third energy level to the second energy level, it must release energy.

Answer:

  1. Because electrons orbit the nucleus like planets orbit the sun.
  2. They differ in energy levels and distances from the nucleus.
  3. 32 electrons.
  4. It must absorb energy to jump from the second to the third energy level.
  5. Release energy.
