Conner Proctor · Answer 1

Option C is the correct. Valence electrons have a higher energy level than those in other filled shells

Explanation:

Electrons must lose energy to move from the first to the second shell. FALSE

The electrons always win energy to move from the first to the second shell.

All the electrons in an atom have similar energy levels FALSE.

They are not neccesary similar. In hydrogen these are the level energy - 13.6 eV, - 3.4 eV, - 1.51 eV, - 85 eV and - 54 eV

Electrons do not have potential energy, just kinetic energy. FALSE

They have both.

Valencia electrons are the last electrons in the last layer. They have as much energy as possible and are responsible for forming bonds with other elements.
