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 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.
Isotope can be referred to as the different versions of the SAME ELEMENT. Such as Chlorine has isotopes of Chlorine - 35 and Chlorine - 37. This will just cause the difference in mass numbers because of the difference in neutrons. Chlorine -35 has 17 protons, 17 electrons and 18 neutrons making it to have a mass number of 35 and Chlorine - 37 has 17 protons, 17 electrons and 19 neutrons making it to have a mass number of 39. Some isotopes can be used in normal chemical reactions but some cannot.
The mass of an element tells you the total mass of protons and neutrons combined together. (It theoretically includes everything including electrons, but since electrons are so small, they generally do not make a big difference to the final mass). As for the atomic number, it is equivalent to the number of protons in an element. Ex Chlorine's atomic number is 17, and it has 17 protons and 17 electrons.
Nitrogen
Chlorine maybe? It has 17 protons and a mass of 35, so 35-17= 18 neutrons.

Chlorine is a non metal element. Mass number of it is 35.
The Atomic Mass is 17
Atomic number = Number of protons = 35 - 18 = 17.So the element is chlorine.

S with 17 neutrons and 16 protons has a mass number of 33 amu
Only protons and neutrons have 1 unit mass each, which form the nucleus. The Electrons that orbit the nucleus are of negligable mass. Therefore; total mass = 9 protons + 10 neutrons = 19 unit mass.
Different isotopes of an element have different masses. This is because different isotopes of an element although they have the same number of protons (which defines the chemistry and therefore defines the element) have different numbers of neutrons.ExampleChlorine-35 Atomic Mass approx. 35 (17 protons, 18 neutrons)Chlorine-37 atomic mass approx. 37 (17 protons, 20 neutrons)
