If a (hypothetical) atom with 30 protons and 44 neutrons undergoes alpha decay: how many protons will be left in the nucleus?
how many neutrons will be left in the nucleus?

Protons = 28

Neutrons = 42

Explanation:

Alpha decay is one of radioactive decay in which the atomic nuclei can be illustrated by the emission or loss of helium particles of mass number 4 and proton number of 2

Because mass number is the sum of protons and neutrons, If a (hypothetical) atom with 30 protons and 44 neutrons undergoes alpha decay, 28 protons will be left in the nucleus and 42 neutrons will be left in the nucleus.

i would say the answer is food.

hope this !

the device is called “ rocket engine”
