Makovka662 [10]

d. The farther an electron is from the nucleus, the greater its energy.

Explanation:

The energy of an electron relates with the distance from the nucleus in that the farther an electron is from the nucleus, the greater its energy.

The nucleus of an atom is where the protons and neutrons are located.

Electrons orbits round the nucleus in certain permissible energy levels.

  • According to quantum mechanics and the Bohr's model of the atom, the energy levels of orbital electron is quantized.
  • The ground state is the state with the lowest energy and close to the nucleus.
  • The outer most electrons are located in the highest energy levels
  • Therefore, the farther an electrons is from the nucleus, the greater its energy
