What is the total number of protons and neutron's in an atom called?
mass number = protons + nuetrons
What is the total mass of the protons and neutrons in an atom called?
The total mass of the protons and neutrons in an atom is called the atomic mass or mass number. It is often represented by the symbol A.
What is the number of protons and neutrons called?
The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.
An atoms what number is the sum of protons and neutrons?
The sum of protons and neutrons in an atom is called mass number.
What particle determines the mass along with the protons of an atom?
Neutrons are the particles that contribute to the mass of an atom, along with protons. Neutrons have a similar mass to protons, but they do not have a charge. The number of protons and neutrons in an atom's nucleus determines its atomic mass.
The number of protons and neutrons is called?
The atomic mass
What particles are added together to determine atomic mass?
The atomic mass of an atom is determined by the sum of the number of protons and neutrons in its nucleus. Protons have a positive charge, and neutrons have no charge. The total number of protons and neutrons in an atom's nucleus is called its mass number.
The combined number of protons and neutrons?
The combined number of protons and neutrons is known as the mass number of an atom. It can be used to calculate the atomic mass by adding the total number of protons and neutrons in the nucleus of an atom.
What they do mass number?
Mass number is about the neutrons and protons. The total of neutrons and protons.
What is the sum of the protons and the neutrons in a nucleus called?
Mass number
What is the total number protons and neutrons in an atom called?
mass number = protons + nuetrons
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
