Can someone help no one is helping me

Answer 2

The atom with the highest mass with 139 protons and 154 neutrons, is atom 3

Step-by-step explanation:

The information given are;

The number of protons, p, the number of electrons, e, and the number of neutrons, n, we have;

p, e, n,

39, 39, 52

40, 40 50

139, 39 154

40, 39 51

Based on the information that the mass of the proton = 1.67262 × 10⁻²⁷ kg

The mass of the electron = 1.094 × 10⁻³¹ kg

the mass of the neutron = 1.674927471 × 10⁻²⁷ kg

We have that the atom with the most number of neutron and proton which is atom 3, has the highest mass

we have
