Atomic Number vs mass number vs. atomic mass vs. atomic weight vs. molecular weight atomic number-Z=protons mass number- A=sum of protons and neutrons -atomic mass: mass number ^^ -atomic weight: weighted average of naturally occurring isotopes (12.011) -molecular weight: add up the atomic weights of each element in a compound subatomic charges aka charge of an electron e= 1.6 x 10^-19 1 electron weighs 1/2000 of a proton

What is an Ion? Atom that has lost or gained an electron What are the 7 diatomic elements? H2, N2, O2, F2, Cl2, Br2, I2 What is an allotrope? Elemental molecules with different formulas i.e. O2 and O3 What is an ionic compound? metal and nonmetal (can be polyatomic too) What is the difference between precision and accuracy? What are the three sig fig rules you need to know? 1. Zeros between nonzero digits are always significant 2. Zeroes at the start of a number are never significant 3...
