Periodic Trends Practice

Front

What is the atomic radius trend in Group 18 elements?

Back

The atomic radius increases down the group as additional electron shells are added.

Front

Which element has the largest atomic radius in Group 18?

Back

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

Front

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

Back

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

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in the gas phase.

Front

Which element has the highest ionization energy among the following: Li, Na, K, Ni?

Back

Nickel (Ni) has the highest ionization energy among these elements.

Front

What is the trend of ionization energy across a period?

Back

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

Front

What is the trend of ionization energy down a group?

Back

Ionization energy generally decreases down a group.

Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

How does electronegativity change across a period?

Back

Electronegativity increases from left to right across a period.

Front

How does electronegativity change down a group?

Back

Electronegativity decreases from top to bottom down a group.
