yes, Calcium (Ca) is very stable before the reaction because it has a large cloud of valence electrons.
They achieve stable configuration by sharing their electrons in their outermost shell.
Oxygen atoms need to share or gain two electrons in order to achieve a stable electron configuration.
The electron configuration of copper is: [Ar]4s13d10. It isn't 4s23d9 because Cu is able to obtain a more stable electron configuration when it takes an electron from the 4s and adds it to 3d. A half filled 4s and a completely filled 3d is more stable.
Cl-
The expected ground-state electron configuration of copper is ; however, the actual configuration is because a full dsubshell is particularly stable. There are 18 other anomalous elements for which the actual electron configuration is not what would be expected.
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration. Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
The group of elements that have a stable electron configuration are the noble gases.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?

A stable electron configuration.
Cl-
an element with 2 valence electrons can obtain a stable electron configuration by "kicking out" two electrons to have the same electron config as the noble gas in the previous period
By acquiring noble gas configuration elements become stable .
