What is Electronegativity?

Back

Electronegativity is the ability of an atom to attract and accept electrons.

Front

Which element has a greater Electronegativity: N or C?

Back

N (Nitrogen) has a greater Electronegativity than C (Carbon).

Front

List the following elements in order of weakest to strongest ionization energy: P, Cs, Co, Sr.

Back

Cs, Sr, Co, P.

Front

Why does Cs have a larger atomic radius than Na?

Back

Cs has a larger atomic radius than Na because it has more energy levels.

Front

What happens to an atom when it gains electrons?

Back

An atom becomes negative when it gains electrons.

Front

Define Ionization Energy.

Back

Ionization Energy is the energy required to remove an electron from a specific atom.

Front

What is the trend of Electronegativity in the periodic table?

Back

Electronegativity increases across a period and decreases down a group.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy generally decreases.

Front

What is the effect of nuclear charge on atomic size?

Back

A higher effective nuclear charge pulls electrons closer, reducing atomic size.

Front

How does the number of energy levels affect atomic radius?

Back

More energy levels result in a larger atomic radius.
