There are 2 electrons in the 1s orbital so the configuration is 1s2.
How many atoms / electron clouds does helium have ?
Type your answer here... when helium atom removes a electron it forms a helium+ ion.(He+)
No. Helium doesn't form compounds and is neither an electron donor nor an electron acceptor.
Helium has no electron affinity.
Neither. Helium doesn't form compounds and is neither an electron donor nor an electron acceptor.
The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.
Electron configuration of helium: 1s2
Helium has two valence electrons.
two
Yes. Helium, Xenon, and Neon have stable electron numbers (octette rule).
2 valence electrons for helium (helium has only 1 shell)
