(a)
Interpretation:
Sodium mass density shouldbe calculated.
Concept Introduction:
The chemical element sodium has the atomic number 11 and has the symbol Na. It is an alkali metal and it is more unstable. To become stable the element gives up one electron ad it belongs to the periodic table of group 1 having one electron in the outermost shell. When the electron is donated from the outer shell it attains the positive charge and become Na+ cation.
(b)
Interpretation:
Radius of the sodium atom should be calculated.
