Matter Test Review

5. – Neutral particle in the nucleus, just there to keep the peace.
7. – The amount of space an object takes up, even when it’s taking up too much space.
8. – Why elements are grouped together. Similar traits, not similar vibes.
10. – The number that organizes the periodic table, not alphabetically like your contacts.
13. – Mass divided by volume, aka the reason some things float and others sink dramatically.
14. – The packed center of the atom where protons and neutrons hang out.
15. – What must be equal on both sides of a balanced chemical equation.
17. – The tiny building block of everything, smaller than your attention span on a Friday.
18. – Two or more substances mixed together but not chemically bonded. It’s complicated.

1. – Particles so small you cannot see them, even with a microscope and optimism.
2. – A chemical equation that follows the rules and keeps all atoms accounted for.
3. – Positively charged particle chilling in the nucleus like it pays rent.
4. – Negatively charged particle with commitment issues. Always orbiting, never settling down.
6. – The only numbers you’re allowed to change when balancing equations.
9. – The amount of matter in a substance, not how heavy it feels after gym.
11. – Two or more elements chemically bonded like a science power couple.
12. – A pure substance that cannot be broken down without serious chemistry drama.
16. – Anything that has mass and takes up space. Yes, even the homework you forgot.
