Periodic Trends Practice

Front

What is ionization energy?

Back

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

Front

Which element has a lower ionization energy than Scandium (Sc)?

Back

Calcium (Ca) has a lower ionization energy than Scandium.

Front

What is electronegativity?

Back

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

Front

Which element has the lowest electronegativity in Period 3?

Back

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

Front

Which element has a higher electronegativity than arsenic (As)?

Back

Carbon (C) has a higher electronegativity than arsenic.

Front

What happens to atomic size as you move across a period in the periodic table?

Back

Atoms tend to get smaller as you move across a period due to an increase in the number of protons.

Front

What is the trend of ionization energy across a period?

Back

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

Front

What is the trend of electronegativity down a group?

Back

Electronegativity generally decreases as you move down a group in the periodic table.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius decreases, ionization energy increases because the electrons are held more tightly by the nucleus.

Front

What is the significance of the periodic table in understanding element properties?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.
