Front

What is the element with the lowest electronegativity in Period 3?

Back

Sodium (Na)

Front

Define electronegativity.

Back

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

Front

Why do atoms get larger as you move down the periodic table?

Back

Atoms get larger because they have more energy levels.

Front

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

Back

Calcium (Ca)

Front

What is ionization energy?

Back

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

Front

How does electronegativity change across a period in the periodic table?

Back

Electronegativity generally increases across a period from left to right.

Front

How does ionization energy change down a group in the periodic table?

Back

Ionization energy generally decreases as you move down a group.

Front

What is the trend of atomic radius as you move across a period?

Back

The atomic radius generally decreases as you move from left to right across a period.

Front

What is the relationship between electronegativity and ionization energy?

Back

Elements with high electronegativity typically have high ionization energy.

Front

What is the most electronegative element?

Back

Fluorine (F) is the most electronegative element.
