Chemistry Periodic Table Trends

Front

What is the periodic trend for ionization energy across a period?

Back

Ionization energy increases across a period due to increasing nuclear charge.

Front

Which element has the highest electronegativity?

Back

Fluorine (F) has the highest electronegativity.

Front

What is the definition of electronegativity?

Back

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

Front

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

Back

True, anions are larger because they gain electrons.

Front

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

Back

Atomic radius increases down a group due to the addition of electron shells.

Front

Which element has the lowest electronegativity?

Back

Cesium (Cs) has the lowest electronegativity.

Front

What happens to ionization energy as you move down a group?

Back

Ionization energy decreases down a group due to increased distance from the nucleus.

Front

What is the relationship between ionization energy and electronegativity?

Back

Generally, elements with high ionization energy also have high electronegativity.

Front

What is a cation?

Back

A cation is a positively charged ion formed by the loss of one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion formed by the gain of one or more electrons.
