What is the nucleus of an atom?

Back

The nucleus is the central part of an atom, containing protons and neutrons.

Front

What is covalent bonding?

Back

Covalent bonding is a type of chemical bond where two atoms share valence electrons.

Front

What is ionic bonding?

Back

Ionic bonding is a type of chemical bond formed through the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net charge.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the attraction between charged ions, while covalent bonds involve the sharing of electrons.

What is a chemical reaction?

Back

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.
