How many protons and neutrons and electrons does helium-have?
Protons: 2 neutrons: 2 electrons: 2 Helium-3: 2 protons, 1 neutron, 2 electrons Helium-4: 2 protons, 2 neutrons, 2 electrons
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".

2 protons, 2 electrons and 2 neutrons
How many protons neutrons and electrons does the inert gas helium have?
Helium has 2 protons, 2 neutrons, and 2 electrons.
How many protons and electrons does a He have?
Helium has 2 protons and electrons and 1 or 2 neutrons, depending on the isotope.
How many protons electrons and newtrons are in helium?
There are 2 electrons 2 protons and the amount of neutrons depends on the isotope
How many electronsprotonsand neutrons does helium have?
Helium has two protons, and, in its neutral state, two electrons. It can have either one or two neutrons.
How many protons and neutrons electrons in helium?
Helium has two protons, since its atomic number is two. It is an inert element so it also has two electrons. The number of neutrons depends entirely on the isotope. The most common and stable isotope of Helium has 2 neutrons.
How many electrons protons neutrons are in helium?
Helium has two protons, since its atomic number is two. It is an inert element so it also has two electrons. The number of neutrons depends entirely on the isotope. The most common and stable isotope of Helium has 2 neutrons.
