What particles make up the mass of an atom?
The number of protons
What do you add to protons to equal mass number?
The mass number = protons + neutrons
What they do mass number?
Mass number is about the neutrons and protons. The total of neutrons and protons.
What are counted in an an atom to determine mass number?
Atomic Mass: protons AND neutrons atomic number: just protons
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
What is the sum of protons and neutrons in an atom?
Mass number!:)
Sum of protons and neutons?
The sum of protons and neutrons in an atom is referred to as the atomic mass. It is also known as the mass number of an atom and is an important parameter in determining the overall stability and properties of an element. To calculate the atomic mass, you can simply add the number of protons and neutrons present in the nucleus of the atom.
What is the total number of protons and neutron's in an atom called?
mass number = protons + nuetrons
The mass number of an element is equal to the total number of?
protons and neutrons in the nucleus of an atom. It is represented by a whole number and is used to identify different isotopes of an element.
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.
Is the number of protons the mass?
Not necessarily. An estimated form of atomic mass is protons + neutrons.
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
