Helium has 2 electrons.
hydrogen has one electron. Hydride ion is formed when hydrogen gains one electron, and thus hydride ion will also have 2 electrons.

When a helium atom loses an electron then what is formed?
Type your answer here... when helium atom removes a electron it forms a helium+ ion.(He+)
How does the ground state electron configuration of the hydrogen atom differ from that of a ground state helium atom?
The ground state electron configuration of the hydrogen atom is 1s1, and for helium it is 1s2.
As a helium filled balloon rises in the air it becomes?
Larger (the air pressure is dropping as it rises).
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.
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.

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 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 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
Lewis dot diagram for helium?
He :The number of electrons in an atom's outer electron shell determines how many dots there are. Helium has 2 electrons in its outer electron shell, so 2 dots.
What is the aggregate of electrons around the nucleus of an atom?
The number of electrons in a neutral atom will equal the number of protons; the electrons are arranged in concentric shells (at least for atoms heavier than helium; hydrogen and helium both have only one shell, not concentric shells).
What will happen if an electron is brought near an alpha particle?
The alpha particle will grab the electron, making it a part of its electron cloud.? As a result, the helium atom (which is what an alpha particle is) transitions from a +2 charge to a +1 charge.?A second electron will bring the helium atom to neutral, non-ionic, charge.
