Chem '24-'25 Semester 1 Review

Front

As you move down the periodic table, what happens to the size of atoms?

Back

Atoms get bigger because they have more energy levels.

Front

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

Back

Ionization energy decreases.

Front

What is the trend of electronegativity down a group in the periodic table?

Back

Electronegativity decreases.

Front

What is the relationship between frequency and wavelength in the visible light spectrum?

Back

As frequency increases, wavelength decreases.

Front

In the visible light spectrum, which color has the highest frequency?

Back

Violet light has the highest frequency.

Front

What is the definition of ionization energy?

Back

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

Front

What is the definition of electronegativity?

Back

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

Front

What happens to atomic radius as you move from left to right across a period?

Back

Atomic radius decreases due to increased nuclear charge.

Front

What is the trend of metallic character as you move down a group in the periodic table?

Back

Metallic character increases.

Front

What is the significance of the octet rule in chemistry?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.
