Answer:
c) 30
Explanation:
In an atom , the relation between the subatomic particles of the atom are given as follows -
For a neutral atom ,
Atomic number = number of protons = number of electrons ,
Mass number = number of protons + number of neutrons,
Hence , from the given information of the question,
Atomic number of Manganese = 25 ,
mass number of Manganese = 55 ,
Now, to calculate the number of neutrons , the above relation can be used -
Mass number = number of protons + number of neutrons,
Rearranging ,
number of neutrons = Mass number - number of protons
substituting the respective values ,
number of neutrons = 55 - 25 = 30 .
