PERIODIC TRENDS

Front

What is the atomic radius?

Back

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

Front

Which element has the largest atomic radius in Period 4?

Back

Potassium (K) has the largest atomic radius in Period 4.

Front

What happens to atomic radius as you move across a period from left to right?

Back

The atomic radius decreases due to an increase in the number of protons, which increases the attraction to electrons.

Front

What are Transition Metals?

Back

Transition Metals are the elements found in Group B of the periodic table, characterized by their ability to form variable oxidation states.

Front

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

Back

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

Front

What is the trend of electronegativity across a period?

Back

Electronegativity generally increases as you move from left to right across a period.

Front

What is the trend of atomic radius down a group?

Back

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

Front

Which element has the largest atomic radius in Group 18?

Back

Radon (Rn) has the largest atomic radius in Group 18.

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 the trend of ionization energy across a period?

Back

Ionization energy generally increases as you move from left to right across a period.
