How many outer shell are in calcium?
The outer shell of calcium has two electrons.
What atoms need only 2 valence electrons to have a filled outer energy level?
There are two elements which can have a filled outer electron shell with only two electrons, those being the first two elements on the periodic table: hydrogen and helium. Their outer shell is the frist shell, principal quantum number 1. Also note that Hydrogen can also achieve a stable electron configuration with no electrons, in which case it consists of a single, naked proton.
How many electrons does curium have in its outer most shell?
Two electrons
How many electrons does Magnesium have in its outer most shell?
Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.
What are the Every element in group one has one electron in its outer shell Every element in group two has two electrons in its outer shell?
Both statements are true:Every element in group I has one electron in its outer shell andEvery element in group II has two electrons in its outer shell
How many electrons are in the outer shell of calcuim?
Calcium has two electrons in the outer shell.
How many electrons does vandidum have on its outer shell?
Vanadium has on the outer shell two electrons.
How many electrons does it take to fill the outer shell to become like a noble gas?
For most elements, a complete outer shell, like that of a noble gas, has eight electrons. There are exceptions. Helium, which is the most noble of the noble gases, has only two electrons in its outer shell. A few other light elements only need two (and hydrogen can also exist with no electrons at all, in the form of a naked proton, which is also a form of completion for the outer shell).
Does argon has the same number of electrons in its outer shell as magnesium metal?
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
How many outer shell electrons does In have?
Two electrons
How many outer shell are in calcium?
The outer shell of calcium has two electrons.
If carbon has four electrons in its outer shell does it completely fill its outer selectron shell?
Yes. Two of the electrons will go into the carbon's outer s shell (2s) to completely fill it (s orbitals can contain up to two electrons) and the remaining two will go into its outer p shell (2p).
How many electrons in outer shell does seaborgium have?
Two electrons

Does Mercury has two outer electrons?
Yes mercury has two outer electrons the two elements that the two outer electrons would be Iodine and Magnesium.
How many electrons does a maganese have in its outer most shell?
Magnesium has two electrons in its outermost shell.
Does barium have two electrons in its outer p orbitals?
Yes, barium is divalent with two electrons in the outer shell.
