What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms 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

What happens to electrons in ionic bonding?

Back

In ionic bonding, electrons are transferred from one atom to another.

Front

What happens to electrons in covalent bonding?

Back

In covalent bonding, electrons are shared between atoms.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

How do metals in groups 1-3 typically achieve a full outer shell?

Back

Metals in groups 1-3 typically lose electrons to achieve a full outer shell.

Front

What is the charge of an ion formed by losing electrons?

Back

The charge of an ion formed by losing electrons is positive.

Front

What is the charge of an ion formed by gaining electrons?

Back

The charge of an ion formed by gaining electrons is negative.

Front

What is an example of an ionic bond?

Back

An example of an ionic bond is the bond between sodium (Na) and chlorine (Cl) to form sodium chloride (NaCl).

Front

What is an example of a covalent bond?

Back

An example of a covalent bond is the bond between two hydrogen atoms to form H2.
