Periodic Table

Front

What are halogens?

Back

Halogens are elements found in Group 17 (VIIA) of the periodic table, known for having seven valence electrons and being highly reactive.

Front

What property do all halogens share?

Back

Each halogen has seven valence electrons.

Front

What is a metalloid?

Back

Metalloids are elements that have properties of both metals and nonmetals, often being semiconductors of electricity.

Front

Which elements are considered metalloids?

Back

Common metalloids include boron, silicon, germanium, arsenic, antimony, and tellurium.

Front

What is the reactivity of alkali metals?

Back

Alkali metals are very reactive, especially with water, and they tend to lose one electron to form positive ions.

Front

What defines a nonmetal?

Back

Nonmetals are elements that typically do not conduct electricity, are brittle in solid form, and have high ionization energies.

Front

What is the position of noble gases in the periodic table?

Back

Noble gases are found in Group 18 (VIIIA) of the periodic table and are known for being inert and not readily forming bonds.

Front

What is an anion?

Back

An anion is a negatively charged ion that forms when an atom gains one or more electrons.

Front

What is a cation?

Back

A cation is a positively charged ion that forms when an atom loses one or more electrons.

Front

What is the significance of valence electrons?

Back

Valence electrons determine how an element will react chemically and how it will bond with other elements.
