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. Number of protons = number of electrons = atomic number. Number of neutrons = mass number - atomic number. Key fact. Remember that Protons are Positive, and Neutrons are Neutral. Question. Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom's nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral). Like protons, neutrons are bound into the atom's nucleus as a result of the strong nuclear force. Andrew Zimmerman Jones. Updated on January 16, 2018. A proton is a positively charged particle that resides within the atomic nucleus. The number of protons in the atomic nucleus is what determines the atomic number of an element, as outlined in the periodic table of the elements . 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. AXkeo.
