The sum of the numberof protons and nuetrons in the nucleus of an atom?
The sum of the number of the protons and neutrons in the nucleus of an atom is called as atomic mass.
The mass number is used to calculate the number of?
protons and neutrons in an atom. It is the sum of protons and neutrons in the nucleus of an atom.
The mass number is used to calculate the number of what?
The number of protons and neutrons in the nucleus
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
What is the sum of protons and neutrons in an atom?
Mass number!:)
Mass number - atomic number?
The mass number represents the total number of protons and neutrons in the nucleus of an atom. The atomic number specifies the number of protons in the nucleus. The difference between the mass number and atomic number gives the number of neutrons in the nucleus.
What is the atomic mass of a atom?
The atomic mass of an atom is the total mass of protons, neutrons, and electrons in the atom, measured in atomic mass units (amu). It is approximately equal to the sum of the number of protons and neutrons in the atom's nucleus.
The mass number represents the number of?
The mass number is the sum of the neutrons and protons which exist in the atomic nucleus of an isotope.
How is the mass number of a atom indicated?
The mass number is the sum of protons and neutrons in the nucleus of an atom.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
The sum of protons and neutrons in the nucleus of an atom is the?
Atomic Mass. This can vary depending upon the number of neutrons in the nucleus. Whereupon it is known as an ISOTOPE. Do NOT confuse Atomic Mass , with Atomic Number(Z). The Atomic Number is an elements position in the Periodic Table, AND the number of PROTONS in the nucleus.
Define the term mass number?
Mass number is a value approximate to the number of protons (Atomic Number) plus the number of neutrons within an atom of the element considered. I say approximate as mass number takes into account the mass of the nucleus and not the actual number of protons and neutrons in the nucleus.
