The number of protons in a nucleus of an atom is called the "proton number", strangely enough. If you are a physicist, you will most likely prefer this term. Chemists however, would rather call it "atomic number".

The sum of protons and neutrons in an atom is called the mass number.
Wiki User
∙ 16y agoThe number of protons is the atomic number, and the number of protons and neutrons is the mass number (or Atomic Mass number or nucleon number).

How do you obtain the mass number of an atom?
The mass number of an atom is the total number of protons and neutrons in its nucleus. It can be obtained by adding together the number of protons and neutrons in the atom's nucleus. The mass number is typically written as a superscript to the left of an element's symbol.
If uranium has an atomic number of 92 how many protons and neutrons are found in the uranium 238 atom?
In a uranium-238 atom, the number in the isotope name stands for the total number of protons and neutrons in the nucleus. So in this case, uranium-238 has 92 protons (atomic number) and 146 neutrons (238 - 92).
How many particles are in the nucleus for oxygen?

How many protons does potassium 39 have?
The mass number, the number that follows the hyphen at the end of an element name, is the sum of the atomic number of the element and the number of neutrons in each atom of the isotope specified by mass number. The atomic number of potassium is 19; therefore, potassium-39 contains (39 - 19) or 20 neutrons.
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 has to be true about the protons and the electrons on an atom that is neutrral?
In any atom,there are protons, neutrons and electrons. As the name would suggest, neutrons carry no charge. Protons carry a positive charge and electrons carry a negative charge. So in an atom that has no charge there has to be an equal number of protons and electrons.
How many protons neutrons and electrons are there in sulfur?
There are 16 protons, 16 neutrons and 16 electrons in a Sulfur atom. *note it's atomic number- this is the number of protons in an atom of an element. There must be the same number of electrons to balance the charge. The atomic weight minus the number of protons gives you the number of neutrons
What is the name of the location of where the neutrons and protons are in an atom?
They are found in the atom's nucleus.
How do the numbers of protons, number of neutrons, and the mass number related?
mass no. = no. of protons + no. of neutrons
What will be the element name of an atom with 9 potons and 10 neutrons?
The element with 9 protons and 10 neutrons is fluorine-19 (F-19).

What is the name for the atom containing the protons and neutrons?
All atoms contain protons and neutrons (with the only exception of the 1H atom, which has only a single proton).
What is the name of the particle that nucleus of an atom?
Neutrons are protons are present in the nucleus of an atom.
What is the name for the centre of the atom containing the protons and neutrons?
That would be the nucleus of the atom
What is the name of an atom that has 3 protons 4 neutrons?
This is an easy problem to solve if you have a Periodic Table of Elements.# protons + # neutrons = atomic number3 + 4 = 7The element with the atomic number 7 is Nitrogen.
