The Real Periodic Table

Front

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

Back

Atomic radius increases because the valence electrons are further from the nucleus.

Front

What is the electron affinity of Neon (Ne)?

Back

The electron affinity of Neon is zero.

Front

Why does electron affinity decrease moving from top to bottom on the periodic table?

Back

Electron affinity decreases because the valence electrons are further from the nucleus.

Front

What trend occurs in ionization energy as you move from left to right across the periodic table?

Back

Ionization energy increases because effective nuclear charge increases.

Front

Which orbitals do groups 1 and 2 on the periodic table represent in terms of electron configuration?

Back

Groups 1 and 2 represent the s orbitals.

Front

Define effective nuclear charge.

Back

Effective nuclear charge is the net positive charge experienced by an electron in a multi-electron atom, accounting for shielding by other electrons.

Front

What is the trend of atomic radius across a period?

Back

Atomic radius decreases from left to right across a period due to increasing effective nuclear charge.

Front

Explain the concept of ionization energy.

Back

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

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy generally decreases because the outer electrons are further from the nucleus.

Front

What is the significance of the periodic law?

Back

The periodic law states that the properties of elements are a periodic function of their atomic numbers.
