Chemistry Periodic Table Trends

Front

True or False: Anions are larger than their parent atoms.

Back

True. Anions have more electrons compared to their parent atoms, causing their electron cloud to expand to minimize electron repulsions.

Front

What is the periodic trend for electronegativity across a period?

Back

Electronegativity increases across a period.

Front

What is the periodic trend for atomic radius across a period?

Back

Atomic radius decreases across a period.

Front

Which has the largest radius: I or I^-1?

Back

I^-1 has the largest radius.

Front

Which elements in the periodic table have the highest first ionization energies?

Back

Noble gas elements have the highest first ionization energies.

Front

Define electronegativity.

Back

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

Front

What is the trend for ionization energy down a group in the periodic table?

Back

Ionization energy decreases down a group.

Front

What is the trend for atomic radius down a group in the periodic table?

Back

Atomic radius increases down a group.

Front

What is the relationship between atomic size and metallic character?

Back

As atomic size increases, metallic character increases.

Front

What is the trend for electron affinity across a period?

Back

Electron affinity generally increases across a period.
