Answer:
O₂ = 3
CO₂ = 2
element = 4
atom = 1
Step-by-step explanation:
1.) The smallest particle of basic matter.
-----> atom
-----> Atoms are the smallest particle of basic matter. However, there are subatomic particles within atoms, including as electrons, neutrons, and protons.
2.) What is an example of a molecule with different types of atoms?
-----> CO₂
-----> A molecule is made up of more than one atom. This molecule contains two different types of atoms, carbon (C) and oxygen (O).
3.) What is an example of a molecule with the same type of atom?
-----> O₂
-----> A molecule is made up of more than one atom. This molecule contains one type of atom, oxygen (O).
4.) This is a substance with only one type of atom.
-----> element
-----> Element's are unique in the fact that their atoms are slightly different from one another. An element is identified based on the number of protons it contains.
