Nuclear reaction: ¹⁶O + p⁺ → ¹³N + α (alpha particle).<span>
Alpha decay is radioactive decay in
which an atomic nucleus emits
an alpha particle (helium nucleus)
and transforms into an atom with an atomic
number that is reduced by two and mass number that is reduced by four.
When oxygen-16 gain one proton, atomic mass is 17, but when lose alpha particle atomic mass reduces by four to 13.</span>
It’s D,the cold will bring cooler temperatures.....:)
False
The atomic mass equals the protons plus the neutrons
