Answer 1

1. ALL matter is made of atoms.

2. The statement that is NOT true about molecules and compounds is: Compounds are made up of the same type of atom. This is incorrect because compounds are made up of two or more different types of atoms, whereas molecules can consist of the same type of atom, as in diatomic molecules like O₂ or N₂.
