Atomic number
Identify the following statements as true or false. If false correct the existing statement.
a) An increase in atomic number means an increase in both protons and electrons.
b) Adding additional protons to an atom results in an increase in atomic size.
c) Additional layers of electrons tend to make the atom larger.
d) Electrons in the same shell are unable to shield each other from nuclear charge.
Order the following elements in descending order (largest to smallest) according to size and explain your
reasoning – Cs, Na, Mg, P, S, CI
