Yellowstone to Glacier National Park. This is a tremendous route. In fact, 40% of Yellowstone Parkâs visitors also plan to spend time in Montanaâs beautiful Glacier Country, an outdoor hotspot with the perfect splash of arts and culture.n fact, 40% of Yellowstone Parkâs visitors also plan to spend time in Montanaâs beautiful Glacier Country, an outdoor hotspot with the perfect splash of arts and culture.
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#.
Manganese has 25 electrons. Explanation: So on a periodic table, the atomic number(the little number guy above the chemical symbol) is also the number of protons that the atom contains. The number of protons is always the same as the number of electrons unless you got some weird ion thing. So since manganese has 25 protons, it has 25 electrons too. socratic
