The quantum numbers of calcium are: Principal quantum number (n): 4 Angular quantum number (l): 0 Magnetic quantum number (ml): 0 Spin quantum number (ms): +1/2
Francium is a highly radioactive alkali metal element with the atomic number 87 and symbol Fr. It is the second rarest naturally occurring element in the Earth's crust and is extremely unstable, making it difficult to study. Francium was discovered in 1939 by Marguerite Perey.
The chemical symbol of francium is Fr correct !
l=0
Francium and lithium have the same number of valence electrons.
The atomic number of francium is 87.
7 is the atomic number of francium.
Francium is a non metallic element. Mass number of it is 223.
The atomic number of francium is 87.
Francium has 87 protons.

The four quantum numbers for germanium are: Principal quantum number (n) Azimuthal quantum number (l) Magnetic quantum number (ml) Spin quantum number (ms)
The quantum numbers of calcium are: Principal quantum number (n): 4 Angular quantum number (l): 0 Magnetic quantum number (ml): 0 Spin quantum number (ms): +1/2
Francium is in the group 1 (alkali metals) of the periodic table.
There are several different quantum numbers for a given atom (principle quantum number, the angular quantum number, the magnetic quantum number, the spin quantum number, etc) .I assume you are looking for the Principle Quantum number, n, which is equal to the row (period) in the period table in which the element is situated.For helium, the principle quantum number is 1.i.e. n = 1As another example; the principle quantum number for potassium (K), n = 4.
