U3Rvw: PTE Trends

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 has a greater Electronegativity: N or C?

Back

Nitrogen (N) has a greater Electronegativity than Carbon (C).

Front

What is the trend for ionization energy as you move across a period in the periodic table?

Back

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

Front

How is the trend for ionization energy related to the trend for atomic radius?

Back

They are opposites; as atomic radius increases, ionization energy decreases.

Front

What is atomic radius?

Back

Atomic radius is a measure of the size of an atom, typically the distance from the nucleus to the outermost electron.

Front

What happens to atomic size as you move down a group in the periodic table?

Back

Atomic size increases as you move down a group due to the addition of energy levels.

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 (Sc).

Front

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

Back

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

Front

What is the relationship between atomic number and atomic radius?

Back

As atomic number increases, atomic radius generally decreases across a period due to increased nuclear charge.
