H Periodic Table Review Flashcardziz 2025

Front

What is ionization energy?

Back

The energy needed to remove the outermost electron from an atom.

Front

Why does ionization energy increase as you move across a period (Left to Right)?

Back

Proton pull increases, making it harder to remove an electron.

Front

What happens to atomic size as you move to the right across the periodic table?

Back

Atoms tend to get smaller because they have more protons.

Front

What contributes to the greater atomic size of higher atomic number elements within a family of the periodic table?

Back

More shielding of the outer electrons by the inner electrons.

Front

What particle is found in the nucleus and has no charge?

Back

Neutron.

Front

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

Back

Ionization energy decreases as you move down a group.

Front

What is electron shielding?

Back

The phenomenon where inner electrons block the attraction between the nucleus and outer electrons.

Front

How does the number of protons affect the atomic radius?

Back

More protons result in a stronger nuclear charge, pulling electrons closer and reducing atomic radius.

Front

What is the relationship between atomic size and electronegativity?

Back

As atomic size increases, electronegativity generally decreases.

Front

What is the definition of electronegativity?

Back

The ability of an atom to attract electrons in a chemical bond.
