Atomic mass Definition & Meaning Dictionary.com

WebThe dalton or unified atomic mass unit (symbols: Da or u) is a non-SI unit of mass widely used in physics and chemistry. It is defined as 1⁄12 of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest. [1] [2] The atomic mass constant, denoted mu, is defined identically, giving mu = m(12C)/12 ... WebStep-by-step explanation. Isotopes are atoms of same element having same atomic number but different mass numbers. Now, atomic number = number of protons = number of electrons (since an atom is overall electrically neutral). So, isotopes have same number of protons and electrons. But number of neutrons in different isotopes may vary. For example. f150 5 speed automatic
