The nucleus consists of 92 protons and 144 neutrons. How many protons and neutrons will there be in the new nucleus

The nucleus consists of 92 protons and 144 neutrons. How many protons and neutrons will there be in the new nucleus, which is formed after the emission of two a-particles and one b-particle?

A = 92 + 114 = 206, (atomic mass)

Let’s skip two alpha particles:
A = 206 – 4 -4 = 206 – 8 = 198 (after all, we missed two alpha particles, which means we subtract 4 twice. This will now be the atomic mass),
p = 92-2-2 = 88,

Next, let’s skip the beta particle:
A = 198 (the mass will remain the same),
p = 88 + 1 = 89.
Let’s find the number of neutrons:
neutrons = A-p = 198-89 = 109. It turns out,

Answer: 89 protons and 109 neutrons
