Think of a bond as like a wooden board. You have to put in energy to break it.
Answer:
Noble gases
Explanation:
Neon and argon have 8 electrons in their outermost shells. The elements which have 8 electrons in the outermost shell or in the valence shell,are known as the noble gases.
They are important because they are the electrons that help the atom to bond with another atom. They are in the outer most shell. ☺️
The Structure of polypropylene(C3H6)n is linear.
- The chemical formula for polypropylene is (C3H6)n.
- It is a polymer with complex structure and also known as polypropene.
- Polypropylene is similar to polyethylene which belongs to polyolefin groups.
- Generally the polymers are synthesized from the polymerization process.
- What is polymerization?
The process in which atom or small molecules joined together repeatedly to form a polymer with complex structure is called as polymerization.
The repeated unit of atom or small molecule is called monomer
<h3>
