Is hydride ion more stable or less stable than H-atom?
The hydride ion (H-) is more stable than the hydrogen atom (H•) because the extra electron in the hydride ion helps to stabilize the negative charge through electron-electron repulsion. Additionally, the hydride ion benefits from a full electron octet, making it more stable compared to the hydrogen atom, which has an unpaired electron.
When a helium atom loses an electron then what is formed?
When a helium atom loses an electron, it forms a helium ion which is positively charged because it has one less electron than protons. This helium ion is written as He+.
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.
The number of electrons in a helium atom?
Helium has only two electrons. It is the first noble gas in the periodic table and has a full outer electron shell.
If an atom were to have two protons then it would?
It would by definition be Helium (atom number = number of protons = 2) but the nucleus of the stable isotope 4He also contains 2 neutrons (the mass number = total number of p's and n's = 4)
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.

What is Number of orbitals in helium?
Helium has two electrons, and each electron occupies an orbital. Therefore, in a helium atom, there are two orbitals, one for each electron.
What is a possible quantum number set for an electron found in a ground-state helium (He) atom?
A possible quantum number set for an electron in a ground-state helium atom could be n1, l0, m0, s1/2.

What atom has two electron in outer core?
Helium(He)
Does helium atom has the same number of electrons in its outer shell as in magnesium atom?
yes, both helium and magnesium have 2 valence electrons. the difference is that in helium, the 2 electrons make up an entire electron level. In Magnesium, they only make up the s orbital, or 1st electron sub-level.
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 is electronic configuration for hydride ion?
Because hydrogen is the only atom where bonds are made in the 1s shell, hydrogen can make bonds as a hydride ion or a proton. It can also participate in covalent bonds, and form a weak electrostatic bond that is important in biochemical reactions, called a hydrogen bond. The hydride ion can also join with electropositive atoms in an electron-deficient bond called the three center bond.1s^2
