What is the electron shell diagram for helium?
Helium has one energy shell with only 2 electrons in it.
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.
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.
How electrons does a helium atom have in its first shell?
Two electrons.
How many electrons are in the valence shell of He?
There are two electrons in the valance shell of helium. Since this is the first shell, it is filled by two electrons.
How many electrons are in the outer shell of helium?
2 valence electrons for helium (helium has only 1 shell)
How many electron are in the outer shell of helium?
2 valence electrons for helium (helium has only 1 shell)
What has two electrons in the first shell?
This is true for all elements except hydrogen, which has only one.
How many electrons can be found in the outermost shell helium?
2 electrons in the only shell helium has.
What is the atomic number of helium's outer shell?
The outer shell of helium does not have an atomic number, that number belongs to helium itself whose atomic number is 2.
How many spaces are in the valence shell of helium?
Helium has only one shell with a total of 2 electrons.
Two electrons in helium are placed in only one shell while three electrons in lithium occupy two shells?
It is because the two electrons in helium are placed in K-shell. The K-shell has the capacity of only two electrons. Therefore, in Lithium the third electron is placed in the L-shell. You can find the capacity of a shell to hold electrons by the formula 2n2 where n is the shell no.
