How is mass determined in a atom
WebCorrect option is D) The mass number of an atom is the total number of protons and neutrons in an atomic nucleus. The mass number is written either after the element name or as a superscript to the left of an element's symbol. For e.g. for carbon 14, an isotope of carbon, it is written as carbon-12 or 12C. Webmass number: The sum of the number of protons and the number of neutrons in an atom. atomic number: The number of protons in an atom. atomic mass: The average mass of an atom, taking into account all its naturally occurring isotopes. Atomic Number Neutral atoms of an element contain an equal number of protons and electrons.
