Ionic Bonding & Compounds

Front

What is ionic bonding?

Back

Ionic bonding is the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions) that occurs when electrons are transferred from one atom to another.

What is the chemical formula for the compound formed by copper (II) and phosphate?

Back

Cu₃(PO₄)₂

Front

In the chemical formula for an ionic compound, which ion is written first?

Back

The positive ion (cation) is written first.

Front

How can ionic compounds conduct electricity?

Back

Ionic compounds can conduct electricity when dissolved in water, as the ions are free to move.

Front

What happens to nonmetals like chlorine when they form ionic bonds?

Back

Nonmetals like chlorine typically gain electrons when they form ionic bonds.

Front

What is a cation?

Back

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

Front

What is an anion?

Back

An anion is a negatively charged ion that is formed when an atom gains one or more electrons.

Front

What is the significance of subscripts in a chemical formula?

Back

Subscripts indicate the number of atoms of each element in a compound.

Front

What is the formula for the compound formed by manganese (IV) and sulfur?

Back

MnS₂

Front

What is the role of electronegativity in ionic bonding?

Back

Electronegativity is the tendency of an atom to attract electrons; in ionic bonding, a significant difference in electronegativity between two atoms leads to electron transfer.
