The First Week

Some hints were given this week as we reviewed grade 11 chemistry.
(a) Writing formulas-all positive charges and all negative charges equal zero
(b) Putting in the states of the substances: is it a solid, liquid, gas, or is it dissolved in water (aqueous)
(3) Negative ions are named by adding -ide to the root name; examples: chlorine becomes chloride (Cl-), and sulfur becomes sulfide (S-2)

(4) -ate and -ite are ions that contain oxygen
