Periodic Table and Trends Review

Front

Where are the metalloids found on the periodic table?

Back

Metalloids are found along the stair step line that runs diagonally between metals and nonmetals.

Front

Which element has a smaller atomic radius: potassium (K) or bromine (Br)?

Back

Bromine (Br) has a smaller atomic radius than potassium (K).

Front

What is electronegativity?

Back

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

Front

Which element has a higher electronegativity than arsenic (As)?

Back

Carbon (C) has a higher electronegativity than arsenic (As).

Front

What are nonmetals?

Back

Nonmetals are elements that are typically poor conductors of heat and electricity, have a dull luster, and are brittle when solid.

Front

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

Back

Atomic size increases as you move down the periodic table due to the addition of energy levels.

Front

What is the trend in electronegativity across a period?

Back

Electronegativity generally increases from left to right across a period.

Front

What is the trend in atomic radius down a group?

Back

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

Front

What are the characteristics of metals?

Back

Metals are typically shiny, good conductors of heat and electricity, and malleable.

Front

What is the significance of the stair step line on the periodic table?

Back

The stair step line separates metals from nonmetals and indicates the location of metalloids.
