Periodic Trends Test

Front

When an atom loses an electron, the size will

Back

be smaller

Front

When an atom gains an electron, the size will:
a) increase
b) decrease
c) have no change
d) smaller

Back

increase

Front

As you move across the periodic table from left to right, the atomic radius decreases. This is because -

Back

the number of protons increases, so attraction to electrons increases

Front

As you move down the periodic table, why do atoms get bigger?

Back

The atoms have more energy levels.

Front

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

Back

Rn

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

Which of the following will have a higher electronegativity than arsenic (As)? Options: Carbon (C), Neon (Ne), Antimony (Sb), Germanium (Ge)

Back

Carbon (C)

Front
