Elements and Ions - Short Version

Front

What are nonmetals?

Back

Nonmetals are elements that lack the characteristics of metals. They are typically poor conductors of heat and electricity and have higher electronegativities. Examples include hydrogen (H) and helium (He).

What is a halogen?

Back

Halogens are a group of nonmetals found in Group 17 of the periodic table. They are known for their reactivity and include elements like bromine (Br).

Back

Bromine (Br) is a halogen.

Front

What charge do elements in group 16 form when they become ions?

Back

Elements in group 16, such as oxygen (O) and sulfur (S), typically form ions with a charge of 2-.

Front

What is an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net electrical charge.

What is the difference between metals and nonmetals?

Back

Metals are typically shiny, malleable, and good conductors of heat and electricity, while nonmetals are dull, brittle, and poor conductors.
