You think probably at 8 neutrons; in this case the extremely unstable isotope is 10He.
Atomic Mass: 10,0524; Halflife: 2,7.10-21 seconds
What else can I help you with?
An element has 2 protons 2 electrons and 2 neutrons what is the element?
helium
What element has 2 electrons (neutral atom )?
Helium has 2 protons, 2 neutrons, and 2 electrons.
Is 2 protons 2 neutrons and 2 electrons normal?
It is normal for the isotope of the element helium. 2He4 isotope has 2 protons, 2 neutrons and 2 electrons.
What element has 2 electrons 3 protons 4 Neutrons?
There is no such element: an element is neutral, so it has equal numbers of protons and electrons.Impossible:2 protons 4 neutrons and 3 electrons is the IMpossible He-1 isotope with mass number 6 (=2p+4n). Helium does not accept electrons because it is noble.Possible:2 protons 4 neutrons and 2 electrons is (elemental) Helium, isotope with mass number 6 (=2p+4n)3 protons 4 neutrons and 3 electrons is (elemental) Lithium
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)

1) it's spelt Calcium and 2) 20 protons, 20 electrons, 20 neutrons
What element has 12 protons 14 neutrons 10 electrons?
Magnesium2+ because it donated 2 electrons
How many protons neutrons and electrons 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.
How may electrons neutrons protons are foundin the helium atom?
2 protons 2 electrons 2 neutrons 2 protons 2 electrons 2 neutrons don't know
How many protons nuetrons and electrons does a helium at have?
A helium atom has 2 protons, 2 neutrons, and 2 electrons.
