Periodic Table Review

Front

What are transition metals?

Back

Transition metals are elements found in groups 3-12 of the periodic table, known for their ability to form variable oxidation states and colored compounds. Examples include Gold, Copper, Zinc, and Silver.

Front

What does the atomic number represent?

Back

The atomic number represents the number of protons in the nucleus of an atom, which also equals the number of electrons in a neutral atom.

Front

What is the atomic mass of Iodine?

Back

The atomic mass of Iodine is approximately 126.90.

Front

What is a valence electron?

Back

A valence electron is an electron located in the outermost shell of an atom, which can participate in chemical bonding.

Front

Which family of elements is the most reactive?

Back

The Alkali Metals family is the most reactive group of elements in the periodic table.

Front

What are the properties of metals?

Back

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

Front

What are nonmetals?

Back

Nonmetals are elements that lack the characteristics of metals; they are usually poor conductors of heat and electricity and can be gases or brittle solids at room temperature.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals; they are semiconductors and are found along the zig-zag line on the periodic table.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties, allowing for the prediction of element behavior.

Front

What are noble gases?

Back

Noble gases are a group of elements in group 18 of the periodic table that are colorless, odorless, and inert due to having a full valence shell.
