Considering the normal calcium ion Ca2+ it has the same electronic configuration as the noble gas Argon.

An iron atom is a different element than a sodium atom because it has a different ground state electron configuration. In fact, any atom that differs from any other atom in ground state electron configuration is a different element.
Calcium is in group 2, period 4 of the periodic table. It has an electron configuration of 1s2 2s2 2p6 3s2 3p6 3d10 4s2. This shows us that 4 is its valence shell. Therefore, the other 3 shells are its core shells.
7s1 because the definition of valence electrons are the outermost s and p electrons therefore in this case there is only an outermost s electron and therefore the answer is 7s1. NOTE:IT DOES NOT INCLUDE THE D AND THE F ELECTRONS!!!!Other valence configuration examples include;Nitrogen : 2s2 2p3Chlorine : 3s2 2p5Zinc: 4s2Bromine: 4s2 4p5
yes, chlorine is a diatomic molecule, meaning two chlorine atoms can combine together to form a molecule.
fluoride
Sodium fluoride has electron and ionic elements. This is taught in science.
to find the electron dot configuration of an element simply draw dots, symbolizing valance electrons, in a way that they are farthest from each other around the symbol of the element you are using.
Chlorine is a nonmetal. It is only one electron short of a noble gas electron configuration and is much more likely to abstract an electron from some other element than to donate one to some other element.
An iron atom is a different element than a sodium atom because it has a different ground state electron configuration. In fact, any atom that differs from any other atom in ground state electron configuration is a different element.
The arrangement of the electrons in an atom is known as its electron configuration.
Rather than to give a simple number as answer, I suggest to look up Magnesium on wikipedia, where you will even find a picture with the electron configuration. (And this method can be applied to answer the same question for any other element.)
Calcium is itself an element. Elements do not contain other substances.
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.

You can calculate the total capacity of an electron shell using the formula 2n2,... electron shell, it would need 10 electrons: 2 to fill the 1st shell and 8 to fill the2nd. ... In other words, in an atom with 20 electrons (which is the element calcium
