What particles make up the mass of an atom?
The number of protons
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
What is atomic mass number minus protons?
atomic mass number - protons = number or neutrons
Atomic mass is determined by the number of protons plus the number of?
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
What contributes to an atom's atomic number and to its mass number?
An atom's atomic number is determined by the number of protons in its nucleus, which are positively charged. The mass number is the sum of the protons and neutrons in the nucleus, as neutrons contribute to the atom's mass but not its charge.
What is the sum of protons and neutrons in an atom?
Mass number!:)
What is the mass number of 10 protons and 10 neutrons?
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
What particles make up the mass of an atom?
The number of protons
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
What is atomic mass number minus protons?
atomic mass number - protons = number or neutrons
What equals the number of neutrons plus the number of protons in an atom?
The sum of the number of protons and neutrons in an atom is known as the atomic mass. It is equivalent to the mass number of the atom, which represents the total number of protons and neutrons in the nucleus.
Which subatomic particles makes up most of the mass off the atom?
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
What is the total number of protons and neutron's in an atom called?
mass number = protons + nuetrons
What is the mass number of a sulfur atom with 17 neutrons?
S with 17 neutrons and 16 protons has a mass number of 33 amu
Atomic mass is determined by the number of protons plus the number of?
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
The mass number is used to calculate the number of what?
The number of protons and neutrons in the nucleus
