Chemistry Fall Semester Review Part 2

Front

What is the atomic radius trend in Group 18 elements?

Back

The atomic radius increases down the group due to the addition of electron shells.

Front

What is the difference between a group and a period in the periodic table?

Back

A group is a vertical column of elements with similar properties, while a period is a horizontal row of elements.

Front

What are Alkali Metals?

Back

Alkali Metals are soft, silvery elements in Group 1 of the periodic table that are very reactive, especially with water.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals and are found along the 'stair step' line on the periodic table.

Front

Which element has the greater electronegativity: H or F?

Back

Fluorine (F) has a greater electronegativity than Hydrogen (H).

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.

Front

What is the significance of the 'stair step' line in the periodic table?

Back

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

Front

What are the properties of noble gases?

Back

Noble gases are colorless, odorless, and inert gases that do not readily react with other elements.

Front

What is the general trend of atomic radius across a period?

Back

The atomic radius decreases across a period from left to right due to increasing nuclear charge.

Front

What are the characteristics of Transition Metals?

Back

Transition Metals are known for their ability to form various oxidation states and colored compounds.
