An element is a type of matter composed of atoms that all have exactly the same positive charge on their nuclei. Elements make up every material substance.
2 or more elements held together by chemical bonds.
A stable particle with positive charge equal to the negative charge of an electron. Protons are found in the nucleus of an atom.
The electron is a subatomic particle that carries a negative electric charge. It spins around the nucleus of an atom
The neutron is a subatomic particle with no net electric charge and a mass slightly larger than that of a proton. They are usually found in atomic nuclei.
Equals to the number of protons in the nucleus or electrons in the neutral state of an atom of an element
