How do I know if it is an Element?
Fe HI ZnO
NaCl Cr Al
H CuF CO
hydrogen, symbol H, is from the Greek words hudôr (water) and gennan (generate)
oxygen, symbol, O, is from the Greek words oxus (acid) and gennan (generate)
carbon, symbol C, is from the Latin carbo (coal)
lead, symbol Pb, is for plumbum, which is "lead" in Latin
gold, symbol Au, is for aurum, which is "gold" in Latin
curium, symbol Cm, after Pierre and Marie Curie for their contributions to chemistry (Curium was discovered by G. T. Seaborg)
lawrencium, symbol Lr, after Ernest Lawrence
berkelium, symbol Bk, after Berkeley, California where much research was done on discovering new elements
Nonmetals ALWAYS GAIN electron to become stable
The subscripts say: there are 2- NO3 ions for every 1- Cu ion
Cu = 1
N = (2 x 1) = 2
O = (2x3) = 6
What happens when a metal has two electrons to get rid of the nonmetal can only accept one electron?
The rules are :
Li2S = Lithium sulphide
AlI3 = Aluminum Iodide
ZnO = Zinc Oxide
The rules are:
The Rules are:
Na2SO4 = sodium sulphate
KOH = potassium hydroxide
Fe2(SO4)3 = iron(III) sulphate
Pd (ClO)2 = lead(II) hypochlorite
Mono = 1 Penta = 5 Nona = 9
Di = 2 Hexa = 6 Deca = 10
Tri = 3 Hepta = 7
Tetra = 4 Octa = 8
Silicon tetraflouride = SiF4
Diphosphorus trisulphide = P2S3
Sulphur monoxide = SO
copper(II) sulfate• pentahydrate.
1) Suppose you heard "trihydrate." What would you write?
2) Suppose you heard "octahydrate." What would you write?
3) Name this substance: MgSO4• 9 H2O
4) Write the formula for: barium chloride dihydrate
1) trihydrate = • 3 H2O
2) octahydrate = • 8 H2O
3) Magnesium sulfate nonahydrate
4) BaCl2• 2 H2O
