Ionic and covalent bonds

Front

What are ionic bonds?

Back

Ionic bonds are chemical bonds formed between metals and nonmetals, where electrons are transferred from one atom to another.

Front

What determines the number of valence electrons in an element?

Back

The group number of the element on the periodic table helps determine the number of valence electrons.

Front

What types of atoms are involved in covalent bonds?

Back

Covalent bonds are formed between two nonmetals.

Front

What is the result of an ionic bond?

Back

The result of an ionic bond is the formation of charged ions, which are held together by electrostatic forces.

Front

What is a molecular compound?

Back

A molecular compound is a chemical compound formed by covalent bonds, consisting of molecules made up of nonmetals.

Front

How do ionic and covalent bonds differ in terms of electron transfer?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is an example of a molecular compound?

Back

Water (H2O) is an example of a molecular compound.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are important because they determine how an atom can bond with other atoms.

Front

What happens to the electrons in an ionic bond?

Back

In an ionic bond, one atom loses electrons and becomes a positively charged ion, while the other atom gains those electrons and becomes a negatively charged ion.

Front

What is the general property of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points and are often soluble in water.
