Question 1 is The neutrally charged element in the nucleus of an atom = neutron
the number of protons an atom has = atomic number
an atom that has a different number of neutrons than the standard = isotope
protons + neutrons = Atomic mass
positive particle = proton
Question 2 don't understand what you're asking
Question 3 = Protons. If you add or remove a proton, it becomes a different element.
Question 4 = same as 3 "Protons"
Question 5 again don't understand what you're asking
Question 6 = Protons and Electrons. A proton is positive and an electron is negative, so together it balances out
Question 7 is there like a chart or something to go with it? if not then I'll just define isotope. An Isotope is basically atoms of the same element (so the number of protons can't change) and has a different number of neutrons so since neutrons have a prominent mass(or weight(sort of)) relative to electrons then the mass number will be different as opposed to the standard mass number of an element. For example Chlorine(Cl) has 17 protons and 17 neutrons but there are variants of it like Cl-35 which has 17 protons and 18 neutrons.
Simply put an Isotope has a different number of neutrons than protons
