Types of Bonds

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where pairs of electrons are shared between two nonmetal atoms.

Front

What elements generally form covalent bonds?

Back

Covalent bonds are generally formed between two or more nonmetals.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a nonmetal.

Front

What happens to a metal atom when it forms an ionic bond?

Back

When forming an ionic bond, a metal atom loses electrons to form a cation.

Front

What happens to a nonmetal atom when it forms an ionic bond?

Back

When forming an ionic bond, a nonmetal atom gains electrons to form an anion.

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

How does electronegativity affect bond type?

Back

If the electronegativity difference between two atoms is large, an ionic bond is likely to form; if it is small, a covalent bond is likely to form.

Front

What type of bond is formed between Sr and S?

Back

An ionic bond is formed between Sr (Strontium) and S (Sulfur).

Front

What type of bond is formed between Se and Cl?

Back

A covalent bond is formed between Se (Selenium) and Cl (Chlorine).

Front

What is a cation?

Back

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