How many electrons does He and Ca have in its outer shell?
Helium (He) and Calcium (Ca) both have 2 valence electrons.
How many electrons does noble gases have in the outer shell?
8 electrons (except for helium which has 2)
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 does helium has?
Helium has 2 electrons in the 1s orbital. This also means it has 2 valence electrons. For all neutral atoms, the number of electrons is equal to the number of protons (the same as the atomic number). i suggest you get a periodic table.
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.
How many electrons are in the outer shell of helium?
2 valence electrons for helium (helium has only 1 shell)

How many electrons in an helium?
2 electrons as the atomic number of helium is 2
How many electrons are there in outer shells?
Atoms can have a maximum of 8 electrons in their outermost energy level, except hydrogen and helium which can have a maximum of 2 electrons. The number of electrons in the outer shell determines an atom's chemical properties and reactivity.

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.
