There are 2 electrons in the 1s orbital so the configuration is 1s2.
What else can I help you with?
How many electron orbitals does helium have?
How many atoms / electron clouds does helium have ?
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+.
When helium loses electron it becomes?
When helium loses an electron, it becomes a positively charged helium ion (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.
What element has no electron affinity?
Helium has no electron affinity.
What is orbital notation for helium?
Electron configuration of helium: 1s2
What is the number of valency electron in helium?
Helium has two valence electrons.
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 the electron number for helium?
two
Is the helium ion positive or negative?
If one electron has been removed from Helium's electron shell then it is a He+ ion. If both of its electrons have been removed it becomes a He2+ ion. Either way they are both positive ions.
What ions have the same electron configuration as helium?
Lithium ion (Li+) and beryllium ion (Be2+) have the same electron configuration as helium because they both have filled electron shells.
Is the element helium an electron donor or acceptor?
Helium is not an electron donor or acceptor as it has a full outer electron shell (2 electrons). It is classified as a noble gas and is chemically inert, meaning it does not readily form chemical bonds.
