Answer is: <span>the emitted particle is
an alpha particle.
</span>
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>
If it has 2 or more non-metals as well as a metal
Answer:
c
Explanation:
Ice is about 9% less dense. When ice forms, it takes up about 9% more space than it did as a liquid. Thus, a 1 liter container of ice weighs less than a 1 liter container of liquid water, and the lighter material floats to the top.
