UNIT 3: P-Table & Periodic Trends REVIEW

Front

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

Back

Atoms tend to get smaller due to an increase in protons, which increases the coulombic attraction between the nucleus and electrons.

Front

Which group of elements is known as the alkaline earth metals?

Back

Group 2 of the periodic table.

Front

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

Back

Ionization energy increases.

Front

Which element is the most reactive among Li, Be, C, and Ne?

Back

Lithium (Li) is the most reactive.

Front

What is the reason for the increase in ionization energy across a period?

Back

The increase in nuclear charge due to more protons, which attracts electrons more strongly.

Front

What is the trend in atomic radius as you move down a group in the periodic table?

Back

Atomic radius increases as you move down a group due to the addition of energy levels.

Front

Which element has a larger atomic radius: Strontium or Zinc?

Back

Strontium has a larger atomic radius than Zinc.

Front

What are the alkali metals?

Back

Group 1 elements in the periodic table, known for being highly reactive.

Front

What is the significance of the periodic law?

Back

The properties of elements are periodic functions of their atomic numbers.

Front

What is the trend in electronegativity as you move across a period?

Back

Electronegativity generally increases from left to right.
