Question

If the mass number of some atom is 238 and the atomic number is 92, then how many protons, neutrons, and electrons are in the atom?

Answer 1

`\large \boxed{\text{146 p, 92 n, and 92 e}}`

Step-by-step explanation:

Z = 92

∴ n = 92

e = 92

A = p + n = 238

p + 92 = 238

p = 146

`\text{There are $\large \boxed{\textbf{146 p, 92 n, and 92 e}}$ in the atom.}`
