Which element is smaller?
Al
Cl
Which element is smaller?
Be
Ca
Why does atomic size increase down a group?
the atom is adding energy levels
the atom is adding protons and electrons so more attraction
the atom is losing energy levels
Why does atomic size decrease across a period?
the atom is adding protons and electrons so less attraction and a new energy level is added
the atom is adding protons and electrons so more attraction but no new energy level is added
the atom is losing energy levels and has more attraction
What happens to shielding as you move across a period?
increases
decreases
stays constant

the ability to lose electrons
Which element is the most electronegative?
N
O
F
