Question

Determinar o número de massa A, prótons P, elétrons e números de nêutrons N.
​

Answer 1

ba, p= 56, a= 137, e=56, n=81

ba^2+, p= 56, a= 137, e=54, n=81

cl, p= 17, a= 35, e=17, n=18

cl^-, p= 17, a= 35, e=18, n=18

s, p= 16, a= 32, e=16, n=06

s^2-, p= 16, a= 32, e=18, n=06

ra, p= 88, a= 222, e=88, n=134

ra^2+, p= 88, a= 222, e=90, n=134
