Front

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

Back

Calcium (Ca) has a lower ionization energy than Scandium.

Front

What is Atomic Radius?

Back

Atomic radius is the relative size of the atom's electron cloud.

Front

Front

What are the two variables that affect Coulombic Attraction?

Back

Distance and number of protons.

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 decreases.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with others.

Front

How does electronegativity change across a period?

Back

Electronegativity increases across a period from left to right.

Front

What is the definition of electronegativity?

Back

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