In a neutral atom, the number of protons and electrons are equal. In a positively charged ion, also called a cation, the number of protons is greater than the number of electrons.

Learn how to count protons and electrons in ions, and see examples that walk through sample problems step-by-step for you to improve your chemistry knowledge and skills.

Learn if electrons are negatively charged particles. See the negative charge definition and the difference between positively and negatively charged particles.

A molecule with more protons than electrons will also have a positive charge. Do protons have a charge of negative 1? Protons are positively charged subatomic particles.

What is a proton? Find out the proton definition, along with the mass of a proton and a proton's charge. Also, learn where we can find protons in...

Gaining electrons or losing electrons creates an ion. If an atom gains an electron, it has more electrons than protons, creating an overall negatively charged atom of an element.

Atomic mass is the total mass of particles of matter in an atom, i.e., the masses of protons, neutrons, and electrons in an atom added together.

Number of electrons in a cation = Atomic number of the corresponding atom - Number of Charges The following two examples will show how to count protons and electrons in atoms and ions.

Aluminum has 13 protons, 13 electrons, and 14 neutrons. To determine this, look first at the atomic number for aluminum, which is 13. This gives the...

Protons, electrons, and neutrons are the three subatomic particles present in atoms and are each defined by their charge, mass, and location. Protons have a positive charge of +1 and an …
