14.Identify the reason why atoms decrease in size(atomic radius)across a period on the Periodic Table. a. Gravity pulls the electrons in towards the nucleus.
b. Increase in energy levels increases the attraction and thus pulls electron cloud in.
c. Increasing strong positive nuclear charge from the nucleus pulls in the negative electron clouds and increases with the increase in protons and electrons.
d. Electrons lose energy and collapse with an increasing number of electrons and protons.
