Question

An atom's mass number is 125 and its atomic number is 85.how many neutrons does the atom have?

Answer 1

40 Neurons

Step-by-step explanation:

To find the number of neutrons in an atom, you can use the following formula:

Number of Neutrons=Mass Number−Atomic Number

Given that the mass number is 125 and the atomic number is 85:

Number of Neutrons = 125 − 85

Number of Neutrons=125−85

Number of Neutrons = 40
