The number of protons an atom has in its nucleus is given by the atomic number. A quick looks in the periodic table will show that aluminium has an atomic number equal to #13#. This means that any atom that is an isotope of aluminium will have #13# protons in its nucleus. Since you're dealing with a neutral atom, the number of electrons that surround the nucleus must be equal to the number of protons found in the nucleus. Therefore, the aluminium-27 isotope will have #13# electrons surrounding its nucleus. Finally, use the known mass number to determine how many neutrons you have. #color(blue)(mass number = no. of protons + no. of neutrons)#. #no. of neutrons = 27 - 13 = 14#.
Best Answer: In the electron config. , show that the phosphorus has 15 electrons when it is in neutral state. The outermost shell has 5 electrons. Therefore, the inner-shell have 10 electrons. Reason: 1s2 - first orbital 2s2 2p6 - second orbital 3s2 3p3 - third orbital so, third orbital is the outermost shell and it has 2+3=5, 5 electrons in this shell. Inner-shells are the shells that contains in atom, except the outermost shell.
