5 points An atom has a mass number of 65. Its number of
neutrons is the sum of its atomic number and 3. How
many protons, neutrons, and electrons does this atom
have? What is the identity of this atom? *
(justify your answer step by step!)

25 protons, 25 electrons, 30 neutrons. manganese is the identity

Explanation;

x = atomic number -# of protons

The number of neutrons = x + 5

The mass number (sum of protons + neutrons) = 55.

x + (x + 5) = 55

2x + 5 = 55

2x = 50  

x = 25; atomic number 25 = manganese (Mn)

so ;

25 = Protons

30=Neutrons  

25=Electrons
