Why atomic masses aren

The atomic mass (ma or m) is the mass of an atom. Although the SI unit of mass is the kilogram (symbol: kg), atomic mass is often expressed in the non-SI unit dalton (symbol: Da) – equivalently, unified atomic mass unit (u). 1 Da is defined as 1⁄12 of the mass of a free carbon-12 atom at rest in its ground state. The protons and neutrons of the nucleus account for nearly all of the total mass of at… WebCorrect option is A) Atom is made of particles called electrons, neutrons, and protons. Electrons have negligible mass and hence do not contribute much to the mass of an atom. Protons and neutrons contribute to the mass of an atom and are present in a small region called the nucleus. Hence option A is correct. how to reset in squad
