Select all the correct answers.

if a uranium atom undergoes both alpha and gamma decay, what happens to it?

1. the nucleus loses neutrons.
2. the nucleus loses positrons.
3. the nucleus loses protons.
4. the nucleus loses energy.
5. the nucleus loses electrons.

1, 3 and 4.

In an alpha decay, the atom's mass number is reduced by 4, and the atomic number is reduced by two following the emission of an alpha particle (2 protons and 2 neutrons).

In gamma decay, the atom releases energy spontaneously to stabilize itself, and this energy is released in the form of photons.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer
