Front

What is ionization energy?

Back

Ionization energy is the amount of energy required to remove an electron from an atom.

Front

Which atom has the largest atomic radius?

Back

Francium has the largest atomic radius.

Front

Who designed and wrote the first periodic table?

Back

Dmitri Mendeleev designed and wrote the first periodic table.

Front

Which element has the largest electronegativity in the halogens?

Back

Fluorine (F) has the largest electronegativity in the halogens.

Front

Which atom has the largest atomic radius in Group 18?

Front

What trend does ionization energy follow in the periodic table?

Back

Ionization energy generally increases across a period and decreases down a group.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy generally decreases.

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 generally increases across a period from left to right.

Front

How does electronegativity change down a group?

Back

Electronegativity generally decreases down a group.
