1.1: Atoms & Ions Flashcards
(7 cards)
1
Q
Atoms
A
- stable
- neutral charge (equal p+/n)
2
Q
Ions
A
- unstable
- charged particles formed when an atom gains/loses electron
- atoms become ions when valence shell incomplete
3
Q
Cations
A
metal lose electrons = PAWsitively charged
4
Q
Anions
A
non-metals gain electrons = negatively charged
5
Q
Compounds
A
- two elements chemically bond
- form to become stable
6
Q
How is the Periodic Table organization called?
A
Groups are horizontal = # of valence electrons
Periods are vertical = # of ionic charge
7
Q
Types of compounds?
A
Ionic and Covalent Compounds
