Answer:
26 protons, 26 electrons, 30 neutrons
Explanation:
Let P = protons, N = neutrons, E = electrons
The mass number of an atom is the sum of protons and neutrons in the nucleus of the atom.
The number of neutrons is the difference between the mass and atomic numbers of the atom
Therefore, 56 = P + N
where N = 56 - 26
N = 30
That means the number of neutrons is 30
To find P, 56 = P + N, N being 30
56 is now P + 30
56 = P + 30
56 - 30 = P
P = 26
Now, for an atom in its neutral state, the number of electrons is equal to the number of protons
Therefore, E is also 26
