2 valence electrons for helium (helium has only 1 shell)
How many electron does a noble gas have in its last shell?
Helium has 2 electrons in its last (and only) shell. All other noble gases have 8 electrons in its valence shell.
How many electrons can be found in the outermost shell helium?
2 electrons in the only shell helium has.
How many electrons does He and Ca have in its outer shell?
Helium (He) and Calcium (Ca) both have 2 valence electrons.
Does helium has the same amount of electrons in its outer shell as magnesium?
No, helium has 2 electrons in its outer shell, while magnesium has 2 electrons in its outer shell. So, they do not have the same amount of electrons in their outer shell.
What is the electron shell diagram for helium?
Helium has one energy shell with only 2 electrons in it.
Does Helium have 2 electrons in the first shell and 4 in the second?
No, Helium has 2 electrons in total, both of which occupy the first electron shell. The first electron shell can hold a maximum of 2 electrons, so Helium's electron configuration is 2.
