PERIODIC TRENDS

Front

What is the trend in ionization energy as you move down Group 1 of the periodic table?

Back

Ionization energy decreases as you move down Group 1 because the valence electron is further from the nucleus, making it easier to remove.

Front

Which element has the largest atomic radius in Period 4?

Back

Potassium (K) has the largest atomic radius in Period 4.

Front

Define 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 greater electronegativity: Nitrogen (N) or Carbon (C)?

Back

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

Front

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

Back

The atomic radius decreases as you move from left to right across a period due to increasing nuclear charge.

Front

What is the relationship between atomic number and ionization energy?

Back

As atomic number increases, ionization energy generally increases due to increased nuclear charge.

Front

Explain why Francium (Fr) has the lowest ionization energy in Group 1.

Back

Francium has the lowest ionization energy because its single valence electron is far from the nucleus, requiring less energy to remove.

Front

What is electronegativity?

Back

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

Front

How does the number of energy levels affect atomic radius?

Back

As the number of energy levels increases, the atomic radius increases because the outermost electrons are further from the nucleus.

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 due to increased distance between the nucleus and bonding electrons.
