Explanation Given Info: The total nuclear charge of Aluminum is 1.0 C . The atomic number of Aluminum is 13 . Formulae used: To find number of charge particles is the given sample, As, the total charge of sample must be integral multiple of e , therefore total number of charge particles in sample of Aluminum is, n = + q e (I) • q is the net charge on aluminum • n is the number of elementary particles or electrons • e is the elementary charge To find the No. of atoms present in the Aluminum, Number of atoms = Total number of charge particles in a given sample Atomic number N = n A (II) To find number of moles, n m o l e is n m o l e = N N A (III) • N is the number of atoms in the given sample • N A is the Avogadro’s number. To find the mass of the n m o l e moles of Aluminum sample M s a m p l e is, M s a m p l e = n m o l e s × M A l (IV) • M s a m p l e mass of n moles of aluminum sample • M A l molar mass of the Aluminum Calculation: Substitute 1 C for q and 1.6 × 10 − 19 C for e in equation (I) to find n , n = 1 C 1.6 × 10 − 19 C = 6

Atomic Number

Elements are the building blocks of all the matter that exist in the universe. Every element is made up of atoms that have protons, electrons, and a nucleus. In order to know the difference between the elements, an atomic number is used. Every element ha…
