4.0 Chemical Bonds

Front

What type of chemical bond is formed by the attraction between metal atoms and the surrounding sea of electrons?

Back

Metallic bond

Front

Why do atoms share electrons?

Back

To have a full valence shell of electrons

Front

How do covalent bonds form?

Back

By sharing valence electrons between atoms

Front

What is the correct formula for Sodium Chloride?

Back

NaCl

Front

What is the correct formula for Calcium chloride?

Back

CaCl2

Front

Define ionic bond.

Back

A chemical bond formed through the transfer of electrons from one atom to another, resulting in the attraction between oppositely charged ions.

Front

What is a covalent bond?

Back

A chemical bond formed when two atoms share one or more pairs of electrons.

Front

What is the octet rule?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds have unequal sharing of electrons, while nonpolar covalent bonds have equal sharing.

Front

What is a chemical formula?

Back

A representation of a substance using symbols for its constituent elements and numbers to indicate the ratio of atoms.
