Want this question answered?
it is about the atomic number. Calcium is the element.
neodymium is an element, it doesn't have a "chemical" structure are you actually looking for its electron shell structure?
For the electron configuration of aluminum see the link below.
The element calcium, or Ca, is located in group 2, period 4 of the periodic table. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. This can also be written as [Ar] 4s2, because the beginning of that electron configuration is the same as argon's. The 42 you mentioned in your question is referring to a specific isotope of calcium and has nothing to with the electron configuration.
because they need only one element to make noble gas structure.
You don't. Calcium is not an electron, calcium is a element
This chemical element is calcium (Ca).
The number of valence electrons in the atom.
Potassium has one.
The element Calcium (Ca) has 20 electrons according to its atomic number which is 20.
The electron structure of a chemical element Indicate the location of electrons on shells.

Calcium, or Ca
coz its like an element or someink bruv
