Are molecules and atoms the same?
No, molecules and atoms are not the same. Atoms are the basic building blocks of matter, while molecules are made up of two or more atoms bonded together.
Are molecules and particles the same in terms of their composition and structure?
No, molecules are made up of atoms bonded together, while particles can refer to atoms, ions, or molecules. So molecules are a type of particle, but not all particles are molecules.
Do atoms and molecules mean the same thing?
Molecules are made out of atoms, without atoms there are no molecules. Charged molecules (ions) will form compounds as elements do, by combining in whole-number ratios with the ions of other elements and compounds.
What is a pure substance - all the atoms have the same atomic number or number of protons?
A pure substance in which all the atoms have the same atomic number or number of protons is an element.
Must the atoms in a molecule be different?
No, the atoms in a molecule do not need to be all different. Molecules can contain multiple atoms of the same element or different elements bonded together. The arrangement and types of atoms in a molecule determine its properties.
