||||
| MOLECULE | A NEUTRAL GROUP OF TWO OR MORE ATOMS HELD TOGETHER BY COVALENT BONDS.
🗑
|
||||
| COMPOUND | A SUBSTANCE MADE OF TWO OR MORE ELEMENTS CHEMICALLY COMBINED IN A SPECIFIC RATIO, OR PROPORTION.
🗑
|
||||
| PHYSICAL CHANGE | A CHANGE THAT ALTERS THE FORM OR APPEARANCE OF A MATERIAL BUT DOES NOT MAKE THE MATERIAL INTO ANOTHER SUBSTANCE.
🗑
|
||||
