Protons - Answer- Positively charged particles, in nucleus, # determines atomic number Neutrons - Answer- no charge, in nucleus, # determines if if elelmsts are isotopes isotope - Answer- Atoms with the same atomic number but a different atomic mass How isotopes of the same element differ - Answer- Number of neutrons electron shells - Answer- An energy level representing the distance of an electron from the nucleus of an atom. 1st shell - Answer- 2 electrons 2nd shell - Answer- 8 electrons 3rd shell - Answer- 18 electrons Valence shell importance - Answer- outermost electron shell, if it holds less than its max amount then it wants more electrons in order to be "full" Ions - Answer- charged particles Cation - Answer- A positively charged ion Anion - Answer- A negatively charged ion Ionic bond - Answer- A chemical bond resulting from the attraction between oppositely charged ions. ionic bond forms - Answer- by electrons being donated or received covalent bond - Answer- a bond formed when atoms share one or more pairs of electrons polar molecule - Answer- Combination of atoms in which electrical charge is not disturbed symmetrically
