Which of these elements has the smallest atomic radius

The answer choices for this question wasn't provided. Oxygen has the smallest atomic radius. The higher the electronegativity in an element makes the atomic radius smaller.

Which term describes the describes the disorder of random molecular motion

Entropy

Does H2 have a molecular dipole moments

No. H2 does not have a permanent dipole moment.

Why are prefixes not needed in naming ionic compounds

Ions combine in only one ratio, so prefixes are not needed.

What happens to the atomic radius when an electron is gained

The negative ionic radius is larger than the neutral atomic radius

What bond is formed between two identical atoms

A molecular bond

What is the correct electron configuration for an element with 5 electrons in the 3d energy sublevel

1s22s22p63s23p64s23d5

Will two oxygen atoms form an ionic bond

Does two oxygen atoms for an ionic bond
