Front

What happens to the volume of a gas when it is cooled?

Back

The volume will decrease.

Front

Which atom has the largest atomic radius?

Back

Francium.

Front

What is an orbital box diagram?

Back

A visual representation of the electron configuration of an atom, showing the distribution of electrons in orbitals.

Front

Why do atoms get larger as you move down the periodic table?

Back

Because the atoms have more energy levels.

Front

What happens to the electronegativity of elements in group 16 as you move down the group?

Back

The electronegativity decreases.

Front

Define atomic radius.

Back

The distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is electronegativity?

Back

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

Front

Explain the trend of atomic radius across a period in the periodic table.

Back

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

Front

What is the significance of the principal quantum number?

Back

It indicates the energy level and size of an electron shell.

Front

Describe the relationship between energy levels and electron configuration.

Back

Higher energy levels can hold more electrons and are further from the nucleus.
