The atomic number of helium is 2, so there are 2 protons and 2 electrons. In He-4 isotope, there are 2 neutrons.
Helium has an atomic mass of 4.- Number of Protons/Electrons: 2- Number of Neutrons: 2Lithium has an atomic mass of 7.- Number of Protons/Electrons: 3- Number of Neutrons: 4Helium has TWO less neutrons than Lithium.
Helium has 2 protons, 2 neutrons and 2 electrons. The symbol for helium is He and the atomic number is 2.
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
Number of Protons: 35 Number of Neutrons:45 Number of Electrons:35
Protons- 30 Electrons- 30 Neutrons- 35 Zn-65 means the atomic number plus the number of neutrons equals 65. Zinc always has 30 protons; therefore, it's atomic number is 30 and it has 30 protons and electrons. The remaining number is the neutrons: 65-30= 35
Helium-6 has two protons and electrons and four neutrons.
Helium has 2 protons and 2 electrons. He-3 and He-4 isotopes have 1 and 2 neutrons.
Protons: 2 neutrons: 2 electrons: 2 Helium-3: 2 protons, 1 neutron, 2 electrons Helium-4: 2 protons, 2 neutrons, 2 electrons
The number of protons in an element is always the same as the atomic number, which is 2 in the case of helium. (The atomic number is assigned based on the number of protons in an element.) In a neutral atom (one with no charge), the number of electrons equals the number of protons, so it will be 2 electrons also. However, the number of neutrons will vary depending on the isotope (atoms of the same element with different numbers of neutrons). There are two stable isotopes of Helium, 3He and 4He, having 1 neutron and 2 neutrons respectively. Most helium is helium-4, and helium-3 is found as only about one atom in a million.See link below for more information on Helium, as well as the related question below that will show you how to find the number of protons, neutrons, and electrons in any atom.
1 Proton and 1 electron but no neutrons.
Helium is number 2 on the Periodic Table, and the number of its mass is 4. So, therefore it has 2 protons, 2 neutrons, and 2 electrons !
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.

For a standard atom, the number of protons, electrons, and neutrons is the same. For example: 2 Protons - 2 Neutrons - 2 Electrons Helium 3 Protons - 3 Neutrons - 3 Electrons Lithium 4 Protons - 4 Neutrons - 4 Electrons Beryllium So... 53 Protons - 53 Neutrons - 53 Electrons Iodine
