The outer shell of calcium has two electrons.
Calcium has a full 4s sublevel, but does not have a full "outer shell", per se, because it is not a noble gas.
There are 2 electrons in valence shell of calcium. :-)
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Boron has three electrons in its outer shell
The ionic symbol for calcium is Ca^2+. It indicates that calcium has lost two electrons to achieve a stable electron configuration in its outer shell.
Calcium has two electrons in the 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.
Helium (He) and Calcium (Ca) both have 2 valence electrons.
There are 2 electrons in valence shell of calcium. :-)
It's over 9000!
The calcium atom has 2 outer shell electrons. It's configuration is: [Ar] 4s2 it also has 2 inner shell electrons
False - calcium forms ionic bonds very easily because it has only 2 electrons in its outer shell
CaS Because Calcium has 2 electrons in its outer shell- so it needs to get rid of those (Ca2+) Sulfur has 6 electrons in its outer shell- so it needs 2 more to have a full outer shell (S2-)
When calcium reacts with oxygen atoms, the outer shell electrons of calcium are transferred to oxygen atoms. This leads to the formation of calcium oxide (CaO) with calcium losing 2 electrons to form a Ca2+ ion and oxygen gaining 2 electrons to form an O2- ion.
forgot
The calcium atom (Ca) loses two valence electrons to form a calcium ion (Ca2+).
Calcium achieves the octetmost readily not by filling the outermost shell but rather by losing two electrons in the valence shell to form the Ca2+ ion.
