There will be two protons in a helium atom. Here we have to learn an important detail regarding the atomic number.
Atomic number gives the number of protons in an atom. This number primarily decides the name of the atom. Thus, if atomic number is one then it will be named as hydrogen. If the number is found to be two, then that will be named as only Helium. There by a learner must concentrate on this atomic number to know about the atom. If 82 is the atomic number then he has to identify the atom to be lead. Same manner if atomic number is 92 then that atom has to be Uranium.
What will be the number allotted for, say, sodium atom? 11 is that number as there are 11 protons in it. The familiar and costly metal is gold. How many protons will be there in a gold atom? The learner must know about this detail. That number meant for gold is 79 as there are 79 protons in it. If that number is increased by one ie if it goes to 80 then that element will be identified as Mercury. Hence there will be a chance to change mercury into gold by simply taking only one proton from the nucleus of mercury atom.
Just two protons. The number of protons in the nucleus decides the name of the atom. Hence the number of protons is known as Atomic Number. If atomic number is 79, then it is gold atom. If it is 47, then it is silver. If it has 29 protons, then it is copper. 92 is for Uranium. The first with only one proton is Hydrogen.
A helium atom contains 2 protons, as well as 2 neutrons and electrons.
- Name: Helium
- Symbol: He
- Atomic number: 2 (read below what an atomic number is)
- Atomic weight: 4.002602
The atomic number corresponds to the number of protons in the nucleus of an atom of that element. It also corresponds to the number of electrons in the neutral atom.
Helium contains two protons in all of its naturally or artificially occurring states.
There are two protons in a helium atom, and normally two neutrons (4He), although it also exists in nature with just one neutron (3He).

How many positive protons does helium have in its nucleus?
Helium has 2 positive protons in its nucleus.
How many protons and electrons does the element Helium have?
One atom of helium contains 2 protons and 2 electrons. The most abundant isotope of helium, helium-4, has 2 neutrons. The other, rare isotope of helium, helium-3, has 1 neutron. (Source: Wikipedia)
How many protons and nuetrons are in helium?
The normal helium atom has two protons and two neutrons in the nucleus, and two electrons in the "shell".
How many protons nuetrons and electrons does a helium at have?
A helium atom has 2 protons, 2 neutrons, and 2 electrons.
How many protons and neutrons are in the nucleus of a helium-4 atom if it has twice as many protons as a hydrogen atom?
A hydrogen atom has 1 proton in its nucleus. Since the helium-4 atom has twice as many protons as hydrogen, it has 2 protons. Helium-4 also has 2 neutrons, hence the name "4" representing the total number of protons and neutrons.
