Periodic Trends Review

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Which element in Period 3 has the lowest electronegativity?

Back

Argon (Ar) has the lowest electronegativity in Period 3.

Front

What happens to electronegativity as you move across a period from left to right?

Back

Electronegativity generally increases as you move from left to right across a period.

Front

What is ionization energy?

Back

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

Front

How does ionization energy change as you move down a group in the periodic table?

Back

Ionization energy decreases as you move down a group.

Front

What is the trend of atomic radius as you move across a period?

Back

Atomic radius decreases as you move from left to right across a period.

Front

Which type of elements typically have the largest atomic radius?

Back

Metals typically have the largest atomic radius.

Front

What is the relationship between ionization energy and electronegativity?

Back

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

Front

What is the trend of electronegativity as you move down a group?

Back

Electronegativity decreases as you move down a group.

Front

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

Back

Noble gases have very low electronegativity because they have a full valence shell.
