Get started for freeDefine each of the following terms: a. atomic number b. mass number c. isotope d. ion e. atomic mass f. molar mass g. Avogadro's number h. chemical symbol
Group the following elements into three similar groups of two each: \(\mathrm{Na}, \mathrm{O}, \mathrm{Ne}, \mathrm{Li}, \mathrm{Ar}, \mathrm{S}\)
Use the periodic table to write the name and the atomic number of the element that corresponds to each of the following symbols:$$ \begin{array}{lllllllllll} \mathrm{H} & \mathrm{He} & \mathrm{Li} & \mathrm{Be} & \mathrm{B} & \mathrm{C} & \mathrm{N} & \mathrm{O} & \mathrm{F} & \mathrm{Ne} & \\ \mathrm{Na} & \mathrm{Mg} & \mathrm{Al} & \mathrm{Si} & \mathrm{P} & \mathrm{S} & \mathrm{Cl} & \mathrm{Ar} & \mathrm{Fe} & \mathrm{Cu} & \mathrm{Br} \\ \mathrm{Kr} & \mathrm{Ag} & \mathrm{I} & \mathrm{Xe} & \mathrm{W} & \mathrm{Au} & \mathrm{Hg} & \mathrm{Pb} & \mathrm{Rn} & \mathrm{U} & \end{array} $$
