Periodic Trends

Front

What is electronegativity?

Back

Electronegativity is a measure of how well an atom can attract and hold onto electrons.

Front

Which element in Period 3 has the lowest electronegativity?

Back

The element with the lowest electronegativity in Period 3 is Argon (Ar).

Front

What electron configuration represents the most chemically stable atom?

Back

The most chemically stable electron configuration is [Ne] 3s² 3p⁶.

Front

Which is larger: P or P⁻³?

Back

P⁻³ is larger than P.

Front

What is the minimum energy required to remove an electron from the ground state of an atom called?

Back

This is called ionization energy.

Front

What trend in electronegativity is observed across a period in the periodic table?

Back

Electronegativity generally increases across a period from left to right.

Front

What trend in electronegativity is observed down a group in the periodic table?

Back

Electronegativity generally decreases down a group in the periodic table.

Front

How does atomic radius affect electronegativity?

Back

As atomic radius increases, electronegativity typically decreases because the distance between the nucleus and the valence electrons increases.

Front

What is the relationship between ionization energy and electronegativity?

Back

Generally, elements with high electronegativity also have high ionization energy.

Front

What is the significance of noble gases in terms of electronegativity?

Back

Noble gases have very low electronegativity values because they have a full valence shell and do not readily attract electrons.
