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

What ion has 52 protons 76 neutrons and 54 electrons?
The ion with 52 protons, 76 neutrons, and 54 electrons is the ion of element tellurium (Te) with a charge of +2. The number of protons determines the element, the number of neutrons can vary in isotopes, and the number of electrons determines the charge of the ion.
What is the number of protons neutrons and electrons for Helium?
protrons=2 electrons=2 neutrons=2
What element has 19 protons 35 electrons 2 neutrons and 201 particles in the nucleus?
No element could possibly fit this description. There are WAY too many electrons and no where near 201 particles in the nucleus.
What element has 29 protons and 35 neutrons and 27 electrons?
Copper has an atomic number of 29 - so it has 29 protons-- when it has only 27 electrons so it is Cu2+ . The isotope is copper-64
How many protons neutrons and electrons in 40Ca plus 2?
I don't want to do your homework for you. Here's how you figure it out: Protons = atomic number Neutrons = atomic mass - atomic number Electrons = atomic number + ionization

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 electrons and neutrons in the element kalsium?
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.
What element has as many electrons as it has neutrons?
There are particular isotopes that have similar number of electrons and neutrons. Some of these isotopes include hydrogen-2, helium-4, carbon-12 and nitrogen-14.
