Periodic Trends Review

Front

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

Back

Rn

Front

As you move down a group, atomic radius increases because - 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

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?

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

The energy required to remove electrons is the definition of:

Electronegativity is...

Back

the ability of an atom to attract/ accept electrons

Front

Of the halogens, which has the smallest radius? Options: F, Br, He, At
