Helium is an element- the second one in the Periodic Table.
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
Helium atom has 2 electrons.
1 mole of the element has 6.023 x 1023 atoms 1 mole = 4 g of helium = 7 g of lithium = 9 g of beryllium = 11 g of boron = 12 g of carbon = 14 g of nitrogen = 16 g of oxygen
The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.
A molecule of helium is composed of two helium atoms.
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
None, for it to be an atom it has the have the same number of electrons and protons. Something with 1 electron and 2 protons would theoretically be a helium ion but helium does not form ions.
The nucleus of hydrogen has 1 proton, whereas that of helium has 2 protons.
The nucleus of hydrogen has 1 proton, whereas that of helium has 2 protons.
Elements are not species. Helium is an element. Helium can be a single atom.
Helium atom has 2 electrons.
1 mole of the element has 6.023 x 1023 atoms 1 mole = 4 g of helium = 7 g of lithium = 9 g of beryllium = 11 g of boron = 12 g of carbon = 14 g of nitrogen = 16 g of oxygen
The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.
A molecule of helium is composed of two helium atoms.
Yes, helium atom.
This isotope of helium is helium-3; the atomic number of helium is 2.
The sun uses nuclear fusion to produce light and energy. the process is relatively complicated but simplified it looks something like this. step 1: hydrogen atom + hydrogen atom = deutrerium atom (an isotope of hydrogen (one extra neutron)) + positron + neutrino step 2: Deutrerium atom + hydrogen atom = helium 3 (an isotope of Helium (missing one neutron)) + energy step 3: helium 3 atom + helium 3 atom = helium atom + hydrogen atom + hydrogen atom + energy.
