Periodic Table & Trends

Front

What is Electronegativity?

Back

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

Front

Which element has a higher electronegativity: Nitrogen (N) or Carbon (C)?

Back

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

Front

What is the most likely element to have similar properties to Sodium (Na)?

Back

Francium (Fr) is most likely to have similar properties to Sodium (Na) because they are both in Group 1 of the periodic table.

Front

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

Back

Atomic radius increases as you move down a group because you add more shells (energy levels).

Front

Which element is located in period 4 of the periodic table?

Back

Iron (Fe) is located in period 4.

Front

What trend occurs in atomic size as you move across a period from left to right?

Back

Atoms tend to get smaller as you move across a period because the atoms have more protons.

Front

Define 'period' in the context of the periodic table.

Back

A period is a horizontal row in the periodic table, indicating elements with the same number of electron shells.

Front

What is a group in the periodic table?

Back

A group is a vertical column in the periodic table, indicating elements with similar chemical properties.

Front

How does the number of protons affect an element's properties?

Back

The number of protons determines the element's identity and influences its chemical properties.

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.
