16. The molecules of plasma function together, but they are broken down into protons, neutrons, and electrons. Explain why.

it's filtration, but this is an assumption so my apologies if i got this

answer; natural resources;

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

catya your not at all which answer i've seen you do this on another question!
