What else can I help you with?
If i have 2 electrons and the first and second shell what am i?
If you have 2 electrons in the first and second shells, you represent the element Helium (He). Helium has two electrons, both of which occupy the first energy level or shell, making it a stable noble gas. The second shell remains unoccupied in this case, as it requires a minimum of 8 electrons to be filled in accordance with the octet rule.
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.
What is the electron shell diagram for helium?
Helium has one energy shell with only 2 electrons in it.
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.
How many electrons go in the first shell of oxygen?
In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.

How electrons does a helium atom have in its first shell?
Two electrons.
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 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 first and second shell of oxygen?
In the first shell of oxygen, there are 2 electrons, and in the second shell, there are 6 electrons. Oxygen has 8 electrons in total, with 2 of them in the first shell and the remaining 6 in the second shell.

How many electrons go in the first shell of oxygen?
In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.
How many electrons can the second shell of an atom hold?
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
How many electrons are there in the valence shell of a nitrogen atom?
Nitrogen has 5 valence electrons. Its atomic number is 7 therefore it has a total of 7 electrons. If you put this in a Bohr-Rutherford Diagram, there would be 2 electrons in the first shell (Helium structure) and 5 electrons in the outer shell. The number of electrons in an element's outermost shell is its number of valence electrons.
How many electrons are in the outer shell of helium?
2 valence electrons for helium (helium has only 1 shell)
What is heliums first orbital shell second and third?
helium has 2 electrons in its 1st orbital. It doesn't have 2nd or 3rd orbitals.
