99pts. i can't find isotope, pottasium-15 or k-15. is this even possible, i have a fill-in-the-blanks worksheet with a table like example: element name: nitrogen-20 symbol: n-20 atomic number: 7 atomic mass: 20 charge: 0 protons: 7 neutrons: 13 electrons: 7 i remember finding the isotope number, nitrogen-20 by adding the protons and neutrons, then i get a new atomic mass. but on here pottasium-15 is confusing! what neutrons do i add from 19 protons to get 15? sometimes the teacher throws in impossible problems.
