${}_{17}C l^{35} - h a s a t o m i c n u m b e r a s 17 . S o t h e i r p r o t o n s = 17 . M a s s n u m b e r = n u m b e r o f p r o t o n s + n u m b e r o f n e u t r o n s = 35 . N u m b e r o f n e u t r o n s = 35 - 17 = 18 N u m b e r o f e l e c t r o n = n u m b e r o f p r o t o n = 17 .
