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.

∙ 11y agoMaybe lithium. Lithium's atomic number is 3 so the number of protons will be 3. It will lose an electron to attain noble gas configuration. So the no of electrons is 2. The Atomic Mass of lithium is 7 so the number of neutrons should be atomic mass minus the number of protons i.e 7-3=4. According to me it cannot have 2 neutrons.

∙ 7y agoIf 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^-

An example of an atom that has no charge is one that has A 2 protons 2 electrons and 1 neutron B 1 proton 2 electrons and 3 neutrons C 3 protons 1 electron and 3 neutrons?
2 protons, 2 electrons, and 1 neutron
What element has only 1 neutron?
The isotope helium-3 has only one neutron. It has 1 neutron, 2 protons and 2 electrons. You can get an atom's number of neutrons by subtracting its atomic number from its mass (nucleon) number.
What element has 4 protons and 2 electrons?
Beryllium (Be) has 4 protons and 2 valence electrons.
What element has 2 protons 1 neutron and 2 electrons?
Helium has 2 protons, 2 neutrons and 2 electrons. The symbol for helium is He and the atomic number is 2.
What element has 2 valence electrons and 4 protons?
Beryllium (Be) has 4 protons and 2 valence electrons.
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
