I’m pretty sure I think the answer is A the first answer
<span>Since the polonium atom has 84 electrons, it also has 84 protons. The protons have a positive charge (+1), and are in the nuclueus with the neutrons (no charge). The electrons (charge =-1) are NOT in the nucleus, but surround it. Thus, the total charge of the polonium nucleus is +84</span>

<h2>
The process of forming polymers</h2>
- Polymer is formed through a process known as dehydration.
- Hydrogen of one monomer combine with Hydroxyl group of another monomer releasing a molecules of water.
- The monomers that are joined via dehydration synthesis reaction share electrons and form covalent bonds with each other.
- As additional monomer join via multiple dehydration synthesis reaction form a chain of repeating monomer which form polymer.
<h2> The process of breaking down polymers</h2>
- polymers are broken down into monomers through hydrolysis process.
- Water is used during the breakdown process.
- During these reaction polymer is broken in two component whereby if two component are ionized one part gain hydrogen atom and the other gain OH.
