Answer:A
Explanation: because you have to distribute it
Answer:
D
Explanation:
Both images have 4 protons (positive particles) and 4 electrons (negative particles) so in total they don't have a charge. (<em>you don't have to worry about neutrons in this case, because they don't have a charge.)</em>
An ion has a charge so neither image is an ion
<h2>~<u>Solution</u> :-</h2>
Here, we have been given the the amount of helium to be 52 amu.
Thus,
- Atomic mass of Helium is 4u = 2 protons + 2
- Neutrons = 1 atom.
- No. of atoms in 52u = $ \sf{\frac{52}{4}}$ = 13 atoms.
$ \red{\leadsto}$ Hence, the number of atoms will be <u>13 atoms</u>.

Answer:
Radiation therapy is the use of high energy radiation to kill cancer cells.
