Aluminum has an atomic number of 13. How many protons does an atom of aluminum have? How many electrons does it have?
1 Answer
The atomic no.,
Explanation:
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. The atomic number of aluminium is 13. I n the outermost orbit of aluminium atom, 3 electrons are present. Hence, after donating 3 electrons its forms A l + 3 ions, now the number of electrons is 10 and the number of protons is 13. Hence, it carries a positive charge.

Aluminum (aluminium) is the element that is atomic number 13 on the periodic table. Its element symbol is Al and its atomic mass is 26.98. Each atom of aluminum contains 18 protons. Aluminum atoms with fewer than 18 electrons are cations, while those with more than 18 electrons are anions.
Aluminum has (by definition) 13 protons, 13 positively charged particles. Because aluminum is neutral (as is all matter), it therefore has 13 negatively charged particles, electrons. Aluminum has an atomic mass of about
