Periodic Properties

Front

What causes the atomic radius to increase down a group in the periodic table?

Back

The increase in atomic radius down a group is due to the addition of more energy levels (rings) around the nucleus.

Front

What is a vertical column on the periodic table called?

Back

A vertical column on the periodic table is called a Group.

Front

What happens to ionization energy as you move across a row on the periodic table?

Back

Ionization energy increases as you move across a row on the periodic table.

Front

Why does ionization energy decrease down a group?

Back

Ionization energy decreases down a group due to the addition of more energy levels (rings), which makes it easier to remove an electron.

Front

Which element has the largest atomic radius: Cs, K, Na, or H?

Back

Cs (Cesium) has the largest atomic radius.

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 ionization energy?

Back

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

Front

How does the atomic radius change across a period?

Back

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

Front

What is the trend of electronegativity in the periodic table?

Back

Electronegativity increases across a period and decreases down a group.

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.
