∙ 15y agoThe mass number is the total number of protons and neutrons in an atom's nucleus. The number of protons is the same as the element's atomic number, so the number of neutrons is the mass number minus the atomic number. The mass number can be determined by rounding the atomic weight to the nearest whole number. Also, the mass number is given as part of an isotope's name, for instance: Carbon-14 has a mass number of 14.

∙ 12y agoAtomic number is the number of protons and electrons in a neutral atom. Atomic Mass minus atomic number is the number of neutrons in the atom. Neutrons and protons have relatively equal masses and electrons are comparatively "weightless" therefore, the sum of the masses of protons and neutrons equals the atomic mass.

∙ 11y agoAtomic number is equal to the number of protons.
Atomic mass is sum of the number of protons and neutrons.
Wiki User
∙ 11y agoThe mass number of an isotope of an element is the sum of the protons and neutrons in the atomic nucleus.
Wiki User
∙ 6y agoThe atomic weight is the mass of protons, neutrons and electrons; the mass of electrons is not significant.

Are the smaller numbers mass and greater numbers protons?
The mass number is the sum of protons and neutrons.
The mass number of an elements is equal to?
the total number of protons and neutrons in the nucleus.
An isotope is identified by its atomic mass number which is the total number of?
protons and neutrons in the nucleus of an atom. Isotopes of an element have the same number of protons but different numbers of neutrons. The number of neutrons in an atom affects its stability and often determines its nuclear properties.
How is atomic number differ from mass number?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
Is there a relationship between the number of neutrons and protons in the atom is so what type?
Atomic number = number of protons + number of neutrons Mass number = number of protons + number of neutrons
How is isotope and mass number related?
2 isotopes of the same element will have the same number of protons but a different number of neutrons. The sum of protons and neutrons is the mass number, so different isotopes will have different mass numbers.
How is the mass number related to the number of protons and neutrons and atoms has?
The mass number of an element is equal to the number of protons plus the number of neutrons.
Are the smaller numbers mass and greater numbers protons?
The mass number is the sum of protons and neutrons.
Determine the numbers of electrons protons neutrons 80 35 Br?
Number of Protons: 35 Number of Neutrons:45 Number of Electrons:35
What are the different numbers of neutrons called when two atoms have the same number of protons?
Two atoms with the same number of protons but different numbers of neutrons are called "isotopes".
What is the name given to atoms of the same element that have the same number of protons?
Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
What is the mass number of an isotopes that has 5 protons 6 neutrons and selectrons?
The atomic number is the number of protons. The atomic mass number is the the sum of the numbers of neutrons and protons combined, in this instance, 11.
What is the sum of the numbers of protons in the neutrons in the nucleus?
The mass number.
How is the nucleus related to the periodic table?
The nucleus contains the protons and neutrons. The number of protons determines the atomic number of the element and the number of protons and the number of neutrons together determine the atomic mass.
How many protons and neutrons are there in the nucleus of an atom that has an atomic number of 84 and a mass number of 210?
84 protons, the same as the atomic number, and (210 - 84) or 126 neutrons. The numbers of protons and neutrons together equals the mass number.
Isotopes have the same number of but different numbers of?
The number of protons (and electrons in a neutral atom) is identical. The number of neutrons is different for each isotope.
Is the atomic number of an atom equal to the number of protons or neutrons or electrons in the nucleus?
No, atomic number equals the number of protons.The number of neutrons is NOT specific to an element, and various atoms of the same element can have different numbers of neutrons - these are called isotopes.
