What else can I help you with?
What particles make up the mass of an atom?
The number of protons
What they do mass number?
Mass number is about the neutrons and protons. The total of neutrons and protons.
What do you add to protons to equal mass number?
The mass number = protons + neutrons
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 total number of protons and neutron's in an atom called?
mass number = protons + nuetrons
Which subatomic particles are closest in mass?
Protons and nuetrons Dom says: Protons and Neutrons.
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 the mass of an atom with 13 protons and 14 neutrons?
The mass of an atom is primarily determined by the sum of its protons and neutrons. To find the mass of an atom with 13 protons and 14 neutrons, add the total number of protons and neutrons together: 13 protons + 14 neutrons = 27. The approximate mass of this atom would be 27 atomic mass units (amu).
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
What Make up nearly all of an atoms mass?
The sum of all protons and neutrons - Apex Learning
