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!:)
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 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.
Is mass located in an atom's nucleus or in its protons?
The mass of an atom is concentrated in the nucleus, which is made up of protons and neutrons.
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.
Why atomic mass is different from the mass numbers?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
What is the atomic mass of a atom?
The atomic mass of an atom is the total mass of protons, neutrons, and electrons in the atom, measured in atomic mass units (amu). It is approximately equal to the sum of the number of protons and neutrons in the atom's nucleus.
If the atomic mass of an atom is 48 and the atom contains 20 protons how many neutrons does the atom contain?
If the atomic mass of the atom is 48 and it contains 20 protons, then the atom contains 28 neutrons. This can be calculated by subtracting the number of protons from the atomic mass, since the atomic mass includes both 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.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
