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.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

What is the ionic formula for Calcium and Phosphate?

Back

Ca₃(PO₄)₂

Front

Which elements are most likely to form ionic bonds?

Back

Ionic bonds typically form between metals and nonmetals, such as Cesium (Cs) and Oxygen (O).

Front

What is a polyatomic ion?

Back

A polyatomic ion is a group of covalently bonded atoms that carry a charge, such as sulfate (SO₄²⁻) or phosphate (PO₄³⁻).

Front

What is the difference between ionic and covalent bonds?

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 type of elements typically form covalent bonds?

Back

Covalent bonds typically form between nonmetals.

Front

What is the significance of the octet rule in bonding?

Back

The octet rule states that 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 an example of an ionic compound?

Back

An example of an ionic compound is sodium chloride (NaCl), formed from sodium (Na) and chlorine (Cl).
