Web7 jan. 2024 · The atomic number of an element is the number of protons an atom of that element contains. Because both protons and neutrons are found in the atomic nucleus, they are collectively known as nucleons. Protons, like neutrons, are hadrons, composed of three quarks (2 up quarks and 1 down quark). Word Origin The word "proton" is Greek for "first."
An ion is defined as an atom or molecule that has gained or lost one or more of its valence electrons, giving it a net positive or negative electrical charge. In other words, there is an imbalance in the number of protons (positively charged particles) and electrons (negatively charged particles) in a … Meer weergeven The term "ion" was introduced by English chemist and physicist Michael Faraday in 1834 to describe the chemical species that travels from one electrode to another in aqueous … Meer weergeven Ions can be grouped into two broad categories: cations and anions.
