Positively charged helium atoms deprived of electrons. (2 protons 2 neutrons)
Helium itself is an element and it forms no chemical compound whatsoever, therefore, it is a noble gas. The atom of Helium is so inert that it cannot even form a molecule with another atom of Helium, hence is monoatomic.
Not normally - but it can be ionized.
Niether. In 2015, the largest known atom belonged to ununoctium.
The same size as it is in a Helium atom
No. the size of helium is the same everywhere.
Elements are not species. Helium is an element. Helium can be a single atom.
there are 2 protons in a helium atom there are 2 protons in a helium atom
Helium atom has 2 electrons.
Type your answer here... when helium atom removes a electron it forms a helium+ ion.(He+)
it depends on the atom! For Hydrogen the atomic size could be described as '1' as it is the first atom and has 1 proton, 1 neutron and 1 electron. Then helium would be 2 and so on. Though we tend to use the size of the carbon atom to make relevent sizes to every other atom.
Yes, helium atom.
The nucleus of a helium atom is composed of two protons and two neutrons. Alpha particles have the same composition as the nucleus of a helium atom.
Helium is an element- the second one in the periodic table.
You draw an atom cut in half and mark point A where the helium is.
