A calcium atom will normally lose its two valence electrons, which have principal quantum number 4, to a more electronegative atom when forming a compound. When this happens, the already filled electron shell with principal quantum number 3 becomes the outer shell of the resulting calcium cation, and this cation has the electronic structure of the noble gas preceding calcium in the Periodic Table, neon
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.
outer shell electrons are knows as Valence Electrons
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
The valence electrons are involved in chemical bonding.
Electron outer shell tee hee =^-^=
There are 2 electrons in valence shell of calcium. :-)
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.
The outer shell is called the valence shell
outer shell electrons are knows as Valence Electrons
Valence Electrons
4V V-Valence Electrons Valence Electrons-Last electron (which is on the outer shell)
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
The valence electrons
The valence shell is the outer most shell or imaginary orbit of an atom containing <8 electrons. The electrons in this shell are called 'valence electrons'.

valence electrons are the electrons on the outer-most shell of electrons
The outer shell of calcium has two electrons.
