Covalent Bonding Test Review

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.

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 is a covalent compound?

Back

A covalent compound is a chemical compound formed by the sharing of electrons between nonmetal atoms.

Front

What is the general formula for a covalent compound formed between two nonmetals?

Back

The general formula is represented by the symbols of the elements involved, with subscripts indicating the number of atoms.

Front

What is the significance of valence electrons in covalent bonding?

Back

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

Front

How do you determine the molecular formula of a covalent compound?

Back

The molecular formula is determined by counting the number of each type of atom present in the molecule.

Front

What is the formula for diphosphorus trioxide?

Back

The formula for diphosphorus trioxide is P2O3.

Front

Why are covalent compounds poor conductors of electricity?

Back

Covalent compounds do not have free-moving charged particles, which are necessary for conducting electricity.

Front

What type of bond is formed between a metal and a nonmetal?

Back

An ionic bond is formed between a metal and a nonmetal.

Front

What is the characteristic of ionic compounds in terms of electron transfer?

Back

Ionic compounds are formed when one or more valence electrons are transferred from a metal atom to a nonmetal atom.
