Front

As you move down the periodic table, atoms get bigger because ____________.

Back

The atoms have more energy levels.

Front

The tendency of an atom to attract electrons and acquire a negative charge is called ____________.

Back

electronegativity.

Front

Electronegativity is defined as ____________.

Back

how good an atom is at attracting electrons.

Front

Our modern Periodic Table is organized by increasing ____________.

Back

atomic number.

Front

The element with the largest electronegativity in the halogens is ____________.

Back

F (Fluorine).

Front

What is the atomic number of an element?

Back

The number of protons in the nucleus of an atom.

Front

What is the trend in atomic size as you move across a period from left to right?

Back

Atomic size decreases due to increased nuclear charge.

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom.

Front

What is the trend in ionization energy as you move down a group in the periodic table?

Back

Ionization energy decreases due to increased distance from the nucleus.

Front

What is the relationship between electronegativity and ionization energy?

Back

Elements with high electronegativity typically have high ionization energy.
