Chemistry Honors
Unit 1: Nuclear Chemistry / Atomic Structure
Question | Answer |
---|---|
Electron cloud | Is far away from the nucleus and full of zipping electrons |
Nucleus | It's in the center of an atom, made up of protons and neutrons, and is held together with nuclear energy. It's extremely small and dense. |
Name the subatomic particles in an atom | Protons, neutrons, electrons |
Location, mass, and charge of electrons | Located in the outer region of the atom (electron cloud), has a mass of ~0 amu (much lighter compared to protons or neutrons), and has a negative charge |
Location, mass, and charge of neutrons | Located in the nucleus, mass is 1 amu (heavy!), and has a neutral charge |
Location, mass, and charge of protons | Located in the nucleus, mass is 1 amu (heavy!), and has a positive charge. |
What are the 4 types of matter? | solid, liquid, gas, and plasma |
Atoms | The building blocks of matter and makes up everything. These are extremely TINY, in fact you are made up of trillions and trillions of atoms. |
