Periodic Trends

Front

What is electronegativity (EN)?

Back

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

Front

Which element has a higher electronegativity: Nitrogen (N) or Carbon (C)?

Back

Nitrogen (N) has a higher electronegativity than Carbon (C).

Front

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

Back

Atomic size decreases as you move from left to right across a period due to increased nuclear charge.

Front

What is the trend in electronegativity as you move down a group in the periodic table?

Back

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

Front

Which element has a higher electronegativity: Chlorine (Cl) or Aluminum (Al)?

Back

Chlorine (Cl) has a higher electronegativity than Aluminum (Al).

Front

What is ionization energy?

Back

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

Front

How does ionization energy change as you move across a period?

Back

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

Front

Which element has a lower ionization energy: Calcium (Ca) or Scandium (Sc)?

Back

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

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy generally decreases.

Front

What is the trend in atomic radius as you move down a group in the periodic table?

Back

Atomic radius increases as you move down a group due to the addition of electron shells.
