What does the atomic number tells you about the element?
It tells you (1) how many protons are in the element, and (2) what the element is since all atoms of an element will have the same number of protons.It's D. The number of protons in its atoms.It tells how many protons/electrons that element has.
What is the atomic number of an atom with symbol of CD?
CD is an invalid element symbol. Element symbols must only have one capitalized letter. This is also an invalid substance as there is no element with the symbol "D" However "C" is a valid symbol for Carbon and the atomic number is 6
What element of lowest atomic number contains a half filled d subshell at ground state?
The element with the lowest atomic number that contains a half-filled d subshell at its ground state is scandium (atomic number 21). The electron configuration of scandium at ground state is [Ar] 3d^1 4s^2, where the 3d subshell is half-filled with one electron.
If the atomic number of Element D is 20 then what is the atomic number of R?
If the atomic number of Element D is 20, then Element D is calcium (Ca). The atomic number of calcium is 20, so R would also have an atomic number of 20. This means that R would also be calcium (Ca).
