What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

All atoms of an element with atomic number 38 and mass number 88 contain?
All atoms of the specified data contain 38 protons, 38 electrons (assuming they are not ions), and 50 neutrons. They are atoms of the element Strontium.
What statement is true about atoms protons neutrons and electrons?
Several come to mind. They are both found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. They are nearly the same size, though neutrons are a bit larger. The sum of the protons and neutrons in an isotope of an element is its mass number.
What do you add together to get an atoms mass?
The protons and the neutrons, because those are the only particles in the atom that contain quarks.
What is an atoms mass number?
neutrons + protons = mass number
The particles that make up a sample of matter all have what?
Matter is formed from atoms. Atoms contain protons, neutrons and electrons. Protons and neutrons contain quarks and gluons.
What Make up nearly all of an atoms mass?
The sum of all protons and neutrons - Apex Learning
An atom of an element has 54 protons some of the elements atoms have 77 neutrons while other atoms have 79 neutrons what are the atomic numbers and mass numbers of the two types of atoms of this el?
The atomic number for an element with 54 protons is 54. For the atoms with 77 neutrons, the mass number would be 54 (protons) + 77 (neutrons) = 131. For the atoms with 79 neutrons, the mass number would be 54 (protons) + 79 (neutrons) = 133.
An atoms mass number equals the combination of what two things?
The mass number of an element is equal to the sum of the elements neutrons and protons.
An atoms what number is the sum of protons and neutrons?
The sum of protons and neutrons in an atom is called mass number.
Is an atoms atomic mass is the total mass of its protons an neutrons?
yes
What atomic particle that determines a specific isotope?
Atoms are electrically neutral. The number electrons and number of protons in neutral atoms are same. The number of neutrons in some atoms are same as the number of protons. Example: Calcium atom contains 20 protons and 20 neutrons. But some atoms contain same number of protons but different number of neutrons. For example carbon atoms exist in three forms - all contain 6 protons but some contain 6 neutrons, some 7 neutrons and others with 8 neutrons. These type of atoms are known as isotopes Definition of isotope: Atoms with same number of protons but different number of neutrons It shows that the different number of neutrons determines the existence of isotopes.
