1. I have [tex]^{9}[/tex]Be[tex]^{+}[/tex], [tex]^{12}[/tex]C, and [tex]^{15}[/tex]N[tex]^{+++}[/tex] isotopes, and I need to find the total of protons, neutrons, and electrons.
A = Z + N, where A is the atomic mass number and Z is the number of protons and N is the number of Neutrons.
3. I know this is an easy question, I put it in physics because they asked me this in my physics class. For beryllium, I think there is ONE less electron right? Normally it would be four since there are four protons, so then there are three electrons, three protons and 6 neutrons? Since A is 9, for the others I am still weary, since I got this info online, I just want to know how to get this from the periodic table and just figure it out myself, thanks!
