Chapter 1 section 1 Subatomic particles Flashcards
1
Q
Atoms
A
Matter that makes up our universe.
2
Q
Daltons Atomic Theory
A
- Elements are made of very small particles called atoms.
- Atoms of a specific element have the same size mass and act in exactly the same way.
* atoms of different elements have different sizes, masses, and properties. - Atoms are indivisible and cannot be created or destroyed
- Atoms of different elements combine in simple Whole-number ratios to form chemical compounds.
- Chemical reactions are the result of atoms being rearranged to form new combinations

Q
Location of protons and neutrons
A
held close to the nucleus.
the neutrons are the “glue” that hold protons to close proximity to nucleus.
