How many electrons does it take for the second shell to be considered full?
it takes 8 electrons for the second shell to be considered full
Is the inner lithium shell full?
Yes, Lithium has the Atomic Number 3, therefore has 3 electrons. The inner 'shell' of electrons only needs 2 electrons to be full. The Li+ ion also has a full inner shell.
In what shell do valence electrons locate in?
Valence electrons of any atom are located in the outermost shell that atom carries electrons. For example a carbon atom has 6 electrons: 2e in its first shell (which is full) and 4e (valence electrons) in second shell--there are no electrons farther than second shell for carbon.
Does calcium have a full outer shell?
Calcium has a full 4s sublevel, but does not have a full "outer shell", per se, because it is not a noble gas.
How many electrons are in second shell?
im learning this in science, the most direct answer is 8, the equation to figure this out is 2 times n times n where n is the energy level in this case, 2, so 2 times 2 times 2=8. but once you get to the 18th element (i believe it is potassium) and above this equation no longer applies, but the most number of electrons possible on the second shell is still 8, no matter what element
How many completely full electron shells do the elements in the second row of the periodic table contain?
One, the first shell.
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.
An atom of chlorine has several valence electrons in its what A nucleus Bfirst shell C second shell D third shell?
Third Shell
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.
What happens in the number of electrons in the second shell?
Second shell has a maximum of 8 electrons.
How many middle shell does aluminum have?
Aluminum has 3 electron shells, with the middle shell being the second shell. This second shell is also known as the innermost shell of valence electrons.
Why alkali metals do not show 2 oxidation state?
Because they have only one electron in their valency shell. The second oxidation state would require the atom to lose an electron from its penultimate shell which is full.
