Periodic Trends Assessment

Front

What happens to ionization energy as you move down a group in the periodic table?

Back

Ionization energy tends to decrease because the atoms have more energy levels, making the outer electrons further away from the nucleus, resulting in less attraction.

Front

Which element has a greater electronegativity, aluminum (Al) or sulfur (S)?

Back

Sulfur (S) has a greater electronegativity than aluminum (Al).

Front

What happens to ionization energy as you move across a period in the periodic table?

Back

Ionization energy tends to increase because the atoms have more protons in the nucleus, creating a stronger attraction to the electrons.

Front

Which element has the largest electronegativity?

Back

Fluorine (F) has the largest electronegativity.

Front

Which element has a greater atomic radius, sulfur (S) or tellurium (Te)?

Back

Tellurium (Te) has a greater atomic radius than sulfur (S).

Front

Define ionization energy.

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

What is electronegativity?

Back

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

Front

Explain why ionization energy decreases down a group.

Back

Ionization energy decreases down a group due to increased distance between the nucleus and the outermost electrons, as well as increased electron shielding.

Front

Explain why electronegativity increases across a period.

Back

Electronegativity increases across a period due to the increase in nuclear charge, which attracts bonding electrons more strongly.

Front

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

Back

The atomic radius increases as you move down a group due to the addition of energy levels.
