Front

What is the dot diagram representation of oxygen?

Back

O (Oxygen) has 6 valence electrons represented as: ••O••

Front

What is the electron configuration of oxygen?

Back

1s² 2s² 2p⁴

Front

Which element is represented by the orbital diagram for nitrogen?

Nitrogen (N) has 7 electrons: 1s² 2s² 2p³

Front

Define atomic radius.

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is electronegativity?

Back

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

Front

Explain the shielding effect.

Back

The shielding effect occurs when inner shell electrons block the attraction between the nucleus and the outer shell electrons.

Front

What is ionization energy?

Back

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

Front

Describe the trend of atomic radius in the periodic table.

Back

Atomic radius decreases across a period and increases down a group.
