The sum of the number of the protons and neutrons in the nucleus of an atom is called as atomic mass.
What is the total number of protons and neutron's in an atom called?
mass number = protons + nuetrons
What is the sum of the number of protons and the number nuetrons in an atom?
mass number
What is the sum number of protons and nuetrons in the nucleas of a atom?
The Mass Number.
The mass number of an element is equal to what of an element?
The sum of the number of protons and the number of nuetrons.
What is atomic number and atomic mass or weight?
Atomic number is the number of protons in an atom and atomic mass is the sum of the number of protons and neutrons.
The sum of Which two things is the atomic number in an element?
It is not the sum of two things, but only the number of protons found in the nucleus of the atom. The atomic mass is the total number of neutrons and protons in the nucleus.
The number of protons and nuetrons in the nucleus of an atom?
The number of protons in the nucleus determines the element's identity, while the sum of protons and neutrons gives the atom's mass number. The nucleus contains nearly all of an atom's mass and is surrounded by a cloud of electrons.
The number of protons in an atom is called the atomic mass of the element?
The mass number is the sum of protons and neutrons in the atomic nucleus. The number of protons is equal to the atomic number.
What is the relationship between mass number and atomic numbers?
The mass number is the sum of protons and neutrons in an atom's nucleus, while the atomic number is the number of protons in the nucleus. The atomic number uniquely identifies an element, while the mass number helps determine the atom's mass.
What number is the atomic mass equal to?
The atomic mass of an element is equal to the sum of the number of protons and neutrons in its nucleus. It is not directly related to the atomic number, which represents the number of protons in an atom.
Which term describes the sum of the number of protons and neutrons in an atom?
when you could check in most of atoms that we have you will see that the sum of protons and electrons equals to or is called the atomic weight or atomic mass...that is if you add protons to electrons you have your atomic mass.
