- 3. The separation of elemental metals from the mixtures
- 4. Phase change that involves the conversion from solid to liquid
- 8. Horizontal row in the periodic table
- 10. Formed by losing and gaining of electrons between metal and nonmetal

- 22. Process in which the solid particles are filtered to allow the liquid or filtrate to pass through the filter and be collected as residue
- 24. it is a branch of chemistry that studies the chemical processes within and relating to living organisms. Biochemical processes give rise to the complexity of life.
- 26. Formed when atom loses or gains electron

- 40. Mixture whose a composition varies from position to position within a sample.
- 42. Positively charged subatomic particle of an atom
- 43. it is a branch of chemistry that studies and uses instruments and methods used to separate identify and quantify matter.
- 46. Called as solution a mixture with uniform composition.
- 47. Anything that has mass and occupies space
- 48. states that atoms other than hydrogen tend to form bonds until surrounded by eight valence electrons
- 49. Separates components of mixture at different boiling points.
