PERIODIC TRENDS

Front

Why does atomic radius increase as you move down a group? Options: you add more and more neutrons, you add more and more protons, you add more and more shells (energy levels), you add more atomic mass

Back

you add more and more shells (energy levels)

Front

Atom with the largest atomic radius in Group 18: Ar, He, Kr, Rn

Back

Rn

Front

As you move across the periodic table from left to right, the atomic radius decreases. Why?

Back

the number of protons increases, so attraction to electrons increases

Front

Atom with the largest atomic radius in Period 4 (row 4)

Back

K

Front

Why does Francium (Fr) have the lowest ionization energy in Group 1? Options: it has the smallest number of valence electrons, it has the greatest atomic mass, it has the greatest number of protons, so it attracts its electrons the strongest, its 1 valence electron is very far from the nucleus, so little energy is needed to remove it

Back

its 1 valence electron is very far from the nucleus, so little energy is needed to remove it

Front

Element with the smallest ionization energy in Period 6: Rn, Cs, Os, Tm

Back

Cs

Front

Why do atoms tend to get smaller as you move across the periodic table?

Back

the atoms have more protons.

Front

The energy required to remove electrons is the definition of:
