that's easy.
32 neutrons means that the mass of protons is 25 (as is the electrons) so all i have to do is look for the right one.
simlpy thinking there are 2e (2 electrons on te inner shell) ten each one afterwards has up 8e unless there are no more electrons to fill the shell.
in this case its like this:
2e, 8e, 8e, 7e.
the element is infact manganese in group 5 (Mn).
magnese will react with anything from group one easily at a 1:1 basis and will react with anything from group 2 at a 2:1 basis (the 2 representing magnese).
Nitrogen
The only element which has a reasonably abundant isotope with mass number 33 is sulphur and that has 17 neutrons.
The mass number of an atom is the sum of its protons and neutrons. Chlorine (Cl) has an atomic number of 17, so it has 17 protons. If it has 19 neutrons, then the mass number would be 17 (protons) + 19 (neutrons) = 36. Therefore, the mass number of this chlorine atom is 36.
The number of protons is the atomic mass minus the number of neutrons; in this instance 32 - 17 or 15. An atomic number of 15 corresponds to the element phosphorus; therefore, the isotope is P-32.
The atomic mass of the element with eight protons and nine neutrons is 17 atomic mass units. This is calculated by adding the number of protons and neutrons together, as electrons contribute negligible mass to the overall atomic mass.
Nitrogen
Chlorine maybe? It has 17 protons and a mass of 35, so 35-17= 18 neutrons.
Atomic number = Number of protons = 35 - 18 = 17.So the element is chlorine.

Chlorine is a non metal element. Mass number of it is 35.
The number of protons is the atomic mass minus the number of neutrons; in this instance 32 - 17 or 15. An atomic number of 15 corresponds to the element phosphorus; therefore, the isotope is P-32.
The Atomic Mass is 17
The atomic mass of the element with eight protons and nine neutrons is 17 atomic mass units. This is calculated by adding the number of protons and neutrons together, as electrons contribute negligible mass to the overall atomic mass.
The element with 8 protons is oxygen. To determine the name of the isotope with 9 neutrons, the number of neutrons added to the number of protons gives oxygen-17 which is called oxygen-17.
The atomic number of element X is determined by the number of protons, which is 7. For the second isotope, which has 10 neutrons, the mass number is the sum of protons and neutrons, calculated as 7 protons + 10 neutrons = 17. Therefore, the second isotope has an atomic number of 7 and a mass number of 17.
