kay so i'm in grade 9 and had homework. and i asked my teacher for help and he told me to figure it out myself.. he's such a jerk.... so here are my questions (they're isotopes)
the isotope- the mass number- the atomic number- number of protons- number of electrons- and number of neutrons for the following
chlorine-37
nitrogen-15
gold-197
uranium-235
or tell me how to figure it out!! please help.. i know electrons and protons have the same number.. but i don't know how to figure out the rest!
