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 greater Electronegativity: N or C?

Back

N (Nitrogen) has a greater Electronegativity than C (Carbon).

Front

What happens to atomic size as you move across the periodic table?

Back

Atoms tend to get smaller as you move across the periodic table due to an increase in the number of protons.

Front

Why does Francium (Fr) have the lowest ionization energy in Group 1?

Back

Francium has the lowest ionization energy because its 1 valence electron is very far from the nucleus, requiring little energy to remove it.

Front

What are the vertical columns in the Periodic Table called?

Back

The vertical columns in the Periodic Table are called groups.

Front

What is the trend in 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

Define 'Group' in the context of the Periodic Table.

Back

A group is a vertical column in the Periodic Table that contains elements with similar chemical properties.

Front

What is the significance of the number of protons in an atom?

Back

The number of protons determines the atomic number and identity of the element, influencing its chemical behavior.

Front

How does the number of energy levels affect atomic size?

Back

More energy levels result in a larger atomic size due to increased distance between the nucleus and the outermost electrons.

Front

What is ionization energy?

Back

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