Helium is an element- the second one in the Periodic Table.
What else can I help you with?
What is the ion charge of a helium atom Is it plus 1?
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
How many electrons does an atom of helium have atomic?
Helium atom has 2 electrons.
How many atoms are present in helium lithium beryllium boron carbon nitrogen and oxygen?
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
How many electrons shells does a helium atom have?
The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.
How many atoms are in a molecule of helium?
A molecule of helium is composed of two helium atoms.
What is the ion charge of a helium atom Is it plus 1?
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
What atom contains 1 electron and 2 protons?
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.
How is the nucleus of hydrogen atom different from the nucleus of the helium atom?
The nucleus of hydrogen has 1 proton, whereas that of helium has 2 protons.
How is the nucleus of the hydrogen atom different from the nucleus helium atom?
The nucleus of hydrogen has 1 proton, whereas that of helium has 2 protons.
Is helium atom a single atom species?
Elements are not species. Helium is an element. Helium can be a single atom.
How many electrons does an atom of helium have atomic?
Helium atom has 2 electrons.

How many atoms are in a molecule of helium?
A molecule of helium is composed of two helium atoms.
Where does the sun gets energy from and goes to light and heat?
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.
What that atom has 1 neutron(s) and 2 proton(s). What is its atomic number?
This isotope of helium is helium-3; the atomic number of helium is 2.
Is 'He' an atom?
Yes, helium atom.
