PERIODIC TRENDS

Front

What happens to the atomic radius as you move across the periodic table from left to right?

Back

The atomic radius decreases because the number of protons increases, leading to a stronger attraction to the electrons.

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 do families in the periodic table have in common?

Back

Families in the periodic table have similar properties.

Front

Which element has the smallest ionization energy in Period 6?

Back

Cesium (Cs) has the smallest ionization energy in Period 6.

Front

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

Back

Nitrogen (N) has greater electronegativity than Carbon (C).

Front

Define ionization energy.

Back

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

Front

What is electronegativity?

Back

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

Front

How does atomic radius change down a group in the periodic table?

Back

The atomic radius increases down a group due to the addition of energy levels.

Front

What is the trend of ionization energy as you move down a group?

Back

Ionization energy decreases as you move down a group because the outer electrons are further from the nucleus.

Front

What is the relationship between atomic number and the number of protons in an atom?

Back

The atomic number of an element is equal to the number of protons in its nucleus.
