Periodic Trends Flashcard

Front

What is the atomic radius?

Back

The atomic radius is the distance from the center of the nucleus to the outermost electron.

Front

Which element has a larger atomic radius than Zinc (Zn)?

Back

Strontium has a larger atomic radius than Zinc (Zn).

Front

How does electronegativity change across a period?

Back

Electronegativity increases from left to right within a period.

Front

How does electronegativity change down a group?

Back

Electronegativity decreases from top to bottom within a group.

Front

Which element has a greater electronegativity: Nitrogen (N) or Carbon (C)?

Back

Nitrogen (N) has a greater electronegativity than Carbon (C).

Front

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

Back

Atoms get larger because they have more energy levels.

Front

What is the trend of atomic radius in the periodic table?

Back

Atomic radius generally increases down a group and decreases across a period.

Front

Define electronegativity.

Back

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

Front

What is the relationship between atomic number and atomic radius?

Back

As atomic number increases, atomic radius generally decreases across a period due to increased nuclear charge.

Front

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

Back

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