Chemical Bonding

Front

What is a metal?

Back

A metal is a category of elements that typically lose electrons to form positive ions and have high electrical and thermal conductivity.

Front

What is a nonmetal?

Back

A nonmetal is a category of elements that typically gain electrons to form negative ions and have low electrical and thermal conductivity.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals, often used as semiconductors.

Front

What are noble gases?

Back

Noble gases are a group of elements that are chemically inert due to having a full valence shell of electrons.

Front

What happens to an atom when it loses electrons?

Back

When an atom loses electrons, it becomes a positively charged ion.

Front

What happens to an atom when it gains electrons?

Back

When an atom gains electrons, it becomes a negatively charged ion.

Front

What type of bond is formed between metals and nonmetals?

Back

An ionic bond is formed between metals and nonmetals.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when one atom transfers electrons to another atom, resulting in the attraction between oppositely charged ions.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond that occurs when two atoms share one or more pairs of electrons.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move.
