How many electrons does helium have in its outer shell?
2.You are in terrible need of a periodic table. It's really not that difficult, and it's well worth learning.
How many electrons would hydrogen need to have a full outer she?
Hydrogen has one electron in its outer shell and typically needs one more electron to achieve a full outer shell, which would complete its valence shell with two electrons (like helium). Therefore, hydrogen would need one additional electron to have a full outer 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.
How many electrons are in the outer shell of helium?
2 valence electrons for helium (helium has only 1 shell)
How many electron pairs are in the outer shell of nitrogen?
Nitrogen has 5 electrons in its outer shell, so there are 3 electron pairs in the outer shell of nitrogen.
How many electrons are found in the outer lever of all the noble gases except helium?
There are 8 electrons in the outer level of all the noble gases except helium. This full outer level gives them stability and makes them less reactive. Helium, as a noble gas, has only 2 electrons in its outer level.
