If it has 2 protons, it has to be Helium. Helium atom has 2 electrons also, so if it has 3 electrons, it would be He^-

What element has 2 electrons 3 protons and 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 electrons and protons lithium have?
The element lithium has 3 protons and 3 electrons.

How many protons in lithiun?
Lithium is element 3 on the periodic table and has 3 electrons and 3 protons
What element has 3 protons 2 neutron and 2 electrons?
The type of a element is determined by the number of protons it carries. The element which have to protons is helium. An instance of the element with more electrons than protons, which makes it negatively charged, is called a anion or a negative ion. However, helium is one of, what are called, inert gases. The number of electrons in an inert gas is at the most stable number. It is quite hard to add or extract electrons from an inert gas. So without sounding absolute, He(-) is quite hard to come by.
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 3 protons and 3 electrons?
The only element with three protons is lithium.The isotope lithium-6, has 3 neutrons and is the rarer of the two stable isotopes of lithium.Most lithium is isotope lithium-7, containing 3 protons, 3 electrons, and 4 neutrons. It makes up about 92.5 percent of the lithium found on Earth.
Number of protons and electrons in lithium?
Lithium has three protons and three electrons. The number of electrons always equals the number of protons. Lithium has two isotopes, one with three neutrons and one with four neutrons.
What has 2 electrons and 2 protons?
The atomic number of an element tells us that atom's number of protons. If the atom is neutral, its number of protons is going to equal its number of electrons. Thus, we need only find the element with the atomic number of 2, which is helium.
What is included in the atomic information for an element?
All atoms have either neutrons protons and electrons or all 3 or 2
What element is (Kr)5s24d105p3?
36 + 2 + 10 + 3 = 51 electrons = 51 protons = Antimony (Sb)
How many protons and electrons are in Li plus 1?
In Li plus 1, the element is lithium (Li) which has 3 protons. Since it has a +1 charge, it means it has lost one electron, so it has 2 electrons.
