WebOct 22, 1995 · The number of protons always equals the number of electrons in an atom, and that number is equal to the atomic number. For instance, carbon has an atomic number of six and therefore has six protons and six electrons. Atomic Mass. The weight of an atom is determined by the number of neutrons and protons that are present in the nucleus. WebMar 22, 2024 · Because atoms are electrically neutral, the number of positively charged protons must be equal to the number of negatively charged electrons. Since neutrons do not affect the charge, the number of neutrons is not dependent on the number of protons and will vary even among atoms of the same element. Atomic Number

This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67 × 10 -27 kilograms. Together with neutrons, they make up virtually all of the mass of an atom. blake shelton louisville ky concert
