The atomic number or proton number is defined as the total number of protons in the nucleus and is given the symbol Z. The number of electrons in an electrically-neutral atom is the same as the atomic number. The total electrical charge of the nucleus is therefore +Ze. Source: chemwiki.ucdavis.edu.
A proton is one of the three particles that make up an atom. The other two particles are neutrons and electrons. Protons have a positive charge and are located inside the nucleus along with
A proton is a subatomic particle with a positive charge. It resides in the atomic nucleus. Atoms consist of smaller particles called protons, neutrons, and electrons. Here is the definition of a proton, its electric charge, where it's found in the atom, and a collection of proton facts.
In chemistry, the number of protons in the nucleus of an atom is known as the atomic number, which determines the chemical element to which the atom belongs. For example, the atomic number of chlorine is 17; this means that each chlorine atom has 17 protons and that all atoms with 17 protons are chlorine atoms.
A proton is one of the three main subatomic particles that make up an atom. The other two being neutron and electron. The common symbol for a proton is p or p +. The nucleus of a hydrogen atom or H + ion is an example of a proton. The word 'proton' came from the Greek word meaning 'first'.
