All 31 Terms
| | Term | Definition |
|---|---|---|
| |
Atomic radius | distance between valence electrons and nucleus |
| |
Metals reactions | the more reactive ones are the ones with fewer valence electrons but have a bigger atomic radius because theres less gravitational force so they can break away easy |
| |
nonmetals reations | the closer valence electrons are to the neucleus the more pull they have over new electrons (like from metals) the more reactive ones are the farthest right and closest to the nobel gasses (cause they only need a few electrons to be more nobel) |
| |
ions | are charged substances that arent elements because they dont have the right number of elecrons or neutrons but have the same element symbol as something w/ its # of protons |
| |
covelent bond | bonds where substances share electrons (water) |
| |
polar | where the electrons in a covelent bond spend more time on one side of the atom than the other and give it a charge a little |
| |
non polar | the electrons in covlent bonds that dont have a charge because the electrons dont stay on one side 2 long |
| |
metalic bond | where metals put all their electrons in a pool and they can move around (makes metal be able to bend and conduct elecrticity really well) |
| |
compounds | doner first & add -ide to reciver = how 2 name them (transition metals exept 4 alumium have roman numerals in them) (4 1s w/ metal and nonmetal or metaliods but not just non metals) |
| |
chemical bond | force that holds 2 atoms together (no a force, a bond) |
| |
molecule | neutral atoms bonded covelently |
| |
the way energy level are filled w/ electrons | they have to fill the one level for them to start 2 fill the next energy level (ex. 2, then have to have 8 more before starts to fill the next level) |
| |
diatomic molecules | these are covelent and found in nature - h2 br2 n2 cl2 o2 i2 f2 (its a pattern 2) |
| |
electron dot diagrams | member from that progect thingie? any way theyre diagrams w/ the chemical symbol and dots around it 2 show how many valence electrons it has |
| |
ionic bond | makes 2 ions (transfers electrons) the ions are opisitly charged so since opisits attract they come together and are neutral (also they make crystal lattices alot when they do that) |
| |
crystal lattice | a repeating pattern (ionic bonds mostly) and thats just how the atoms arange them selves |
| |
Ammonium | NH4 |
| |
Actate | C2H2O2 |
| |
Bicarbonate | HCO3 |
| |
Clorate | ClO3 |
| |
Hydroxide | OH |
| |
Nitrate | NO3 |
| |
Carbonate | CO3 |
| |
Sulfate | SO4 |
| |
Phosphate | PO4 |
| |
cu | copper (cuprum) |
| |
au | gold (aurum) |
| |
fe | lead (ferruem) |
| |
pb | tin (plumbum) |
| |
hg | mercury (hydrogyurm) |
| |
ag | silver |
