Ionic and Covalent Bonding

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 is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons, usually occurring between nonmetals.

Define a polyatomic ion.

Back

A polyatomic ion is a group of covalently bonded atoms that carry a charge, such as sulfate (SO4^2-) or ammonium (NH4+).

Front

What is the difference between ionic and covalent bonding?

Back

Ionic bonding involves the transfer of electrons from one atom to another, resulting in charged ions, while covalent bonding involves the sharing of electrons between atoms.

What is the formula for sodium chloride?

Back

The formula for sodium chloride is NaCl, which represents the ionic compound formed from sodium (Na+) and chloride (Cl-).

Front

What type of elements typically form covalent bonds?

Back

Covalent bonds typically form between nonmetals.

Front

What is a chemical bond?

Back

A chemical bond is the force that holds two atoms together in a compound, which can be ionic, covalent, or metallic.

Front

What is the significance of the octet rule in bonding?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is a molecular compound?

Back

A molecular compound is a chemical compound whose simplest units are molecules, formed by covalent bonds between nonmetals.

What is the formula for water?

Back

The formula for water is H2O, which consists of two hydrogen atoms covalently bonded to one oxygen atom.
