How many electrons does He and Ca have in its outer shell?
Helium (He) has 2 electrons in its outer shell. Calcium (Ca) has 2 electrons in its inner shell and 8 electrons in its outer shell.
How many electrons does noble gases have in the outer shell?
8 electrons (except for helium which has 2)
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 e- does helium have?
Helium has two electrons as its atomic number is 2.
How electrons does a helium atom have?
2 electrons. The atomic number is the number of protons and however many protons there are, that is also the number of electrons.
How many electrons are in the outer shell of helium?
2 valence electrons for helium (helium has only 1 shell)
How many electrons does helium has in its outer shell?
2

How many valence electrons are in the outer shell of helium?
2 valence electrons
How many electron are in the outer shell of helium?
2 valence electrons for helium (helium has only 1 shell)
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.
