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 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 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)
What element has 12 protons 14 neutrons 10 electrons?
Magnesium2+ because it donated 2 electrons
If the atomic number of an element is five how many protons does the element have?
Neutrons do not affect the neutrality (or charge) of an atom; protons and electrons do. In order to be neutral, the number of protons must be the same as the number of electrons.
Which element has 19 protons 35 electrons 2 neutrons and 201 particles in the nucleus?
This element doesn't exist.
