Chemical Bonds

Front

What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds.

Front

What are the two main types of chemical bonds?

Back

The two main types of chemical bonds are ionic bonds and covalent bonds.

Front

How is an ionic bond formed?

Back

An ionic bond is formed 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 formed when two nonmetal atoms share pairs of electrons.

Front

What is an ion?

Back

An ion is a charged particle that results when an atom gains or loses electrons.

Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

What type of bond is formed between metals?

Back

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

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the attraction between charged ions, while covalent bonds involve the sharing of electrons between nonmetals.

Front

What is the formula for calculating the total number of atoms in a compound?

Back

To calculate the total number of atoms, sum the subscripts of each element in the chemical formula.

Front

What elements typically form ionic bonds?

Back

Ionic bonds typically form between metals and nonmetals.
