Periodic Trends P6

Front

What is ionization energy?

Back

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

Front

Which element has a lower ionization energy than Scandium (Sc)?

Back

Potassium (K) has a lower ionization energy than Scandium.

Front

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

Back

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

Front

What is electronegativity?

Back

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

Front

Which elements have similar properties in the periodic table?

Back

Elements in the same group (column) of the periodic table have similar properties.

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 due to the addition of electron shells.

Front

Which element has the largest atomic radius in Group 18?

Back

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

Front

How does the number of protons affect atomic size?

Back

An increase in the number of protons pulls the electrons closer to the nucleus, resulting in a smaller atomic size.

Front

What is the relationship between electronegativity and ionization energy?

Back

Elements with high electronegativity typically have high ionization energy, as they hold onto their electrons tightly.

Front

What is the general trend of ionization energy across a period?

Back

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