Is the mass number equal to the number of protons and electrons?

No, it isn't. The mass of an electron is significantly smaller than that of a proton.
The mass of 1,800 electrons is about the same as the mass of one single proton.
The antiparticle of the electron, the positron, has the same mass as the electron.
the mass of the electron is not the same to the mass of the proton

∙ 13y agoProtons and neutrons equal Atomic Mass.
Although an atom has the same amount of protons as electrons, saying that electrons + neutrons = atomic mass would be incorrect as the mass of an electron is, in comparison, very small.
Wiki User
∙ 13y agoNo. Far off. A proton is 1,836 times heavier than an electron
Wiki User
∙ 7y agoNo, but protons have more mass, more than 1800 times the mass, than electrons.
Wiki User
∙ 15y agoit is the sum of the number of neutrons and protons Mass number is the sum of number of neutrons and protons while atomic number is equal to number of protons or electrons..

∙ 12y agoNo, an electron is about 1,836 times smaller than a proton

∙ 13y agoYes, unless it is an ion.

How many protons electrons and neutrons are in Ag?
The number of protons in a atom is equal to the atomic number, therefor Ag has 47 protons. The number of protons and neutrons in an atom is equal to the atomic mass, therefor (108-47= 61) Ag has 61 neutrons. The number of electrons is equal to the number of protons therefor Ag has 47 electrons.
What equals the number of neutrons plus the number of protons in an atom?
The mass number is a whole number that is equal to the sum of protons and neutrons in an atom. Mass number is represented by the letter (A) orA= Z + N (Z) represent the atomic number or the number of protons in the nucleus.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
How do you calculate the number of protons neutrons and electrons of an atom?
The charge of an ion can be calculated by adding up the protons and subtracting the electrons. When oxygen with 8 protons has 8 electrons it is neutral, when it has 7 electrons it is positively charged.
How do you find the number of neutrons protons and electrons in an atom if the atom is neutral?
The number of electrons in an atom is always equal to the number of protons in that same atom. Since the atomic mass of a periodic element equals the weight of the atoms protons AND its neutrons, the following equation can be used to calculate the number of any given particle in an atom: number of neutrons = atomic mass - atomic number
What is The atomic mass of an element is equal to?
The number of protons, electrons, and neutrons:P
What is the atomic mass the same as?
The Atomic Mass is equal to the number of protons and electrons that an element has.
How can the number of proton neutron and electron be calculated to get atomic number and atomic mass?
atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number
What identify the number of protons neutrons and electrons in the atom.?
The number of protons and electrons is equal to the atomic number in a neutral atom.The number of protons is the mass number minus number of protons.
Does the mass number equal the same number of electrons?
The atomic mass number does not equal the number of electrons in the element. The atomic number, on the other hand, does usually equal the number of electrons in the element, With the exception of ions.
How many protons electrons and neutrons are in Ag?
The number of protons in a atom is equal to the atomic number, therefor Ag has 47 protons. The number of protons and neutrons in an atom is equal to the atomic mass, therefor (108-47= 61) Ag has 61 neutrons. The number of electrons is equal to the number of protons therefor Ag has 47 electrons.
What do atomic number and atomic mass mean?
The atomic number is equal to either the number of electrons or the protons of a particular atom. The atomic mass in a.m.u. is equal to the sum of protons and neutrons in an atom.
The atomic mass of an atom is equal to the sum of numbers of what?
protons + electrons= atomic mass NUMBER, not the atomic mass.
What equals the number of neutrons plus the number of protons in an atom?
The mass number is a whole number that is equal to the sum of protons and neutrons in an atom. Mass number is represented by the letter (A) orA= Z + N (Z) represent the atomic number or the number of protons in the nucleus.
Which term describes the sum of the number of protons and neutrons in an atom?
when you could check in most of atoms that we have you will see that the sum of protons and electrons equals to or is called the atomic weight or atomic mass...that is if you add protons to electrons you have your atomic mass.
If an atom 26 protons 26 electrons and 30 neutrons what is it's mass number?
It's Atomic Mass is 56 (and some change) because the majority of the mass comes from the protons and neutrons which equal about 1 amu (atomic mass unit) while the electrons equal a fraction of a percent so just add up the protons and electrons to get the atomic mass henceforth the mass number
How do the numbers of protons, number of neutrons, and the mass number related?
mass no. = no. of protons + no. of neutrons
