Complete the following table for uncharged atoms. $$ \begin{array}{llccc} & & & \text { Number of } & \text { Atomic } \\ \text { Classification } & \text { Group } & \text { Period } & \text { Electrons } & \text { Symbol } \\ \hline \text { Metal } & \- & \- & 11 & \- \\ \- & \text { IVA } & \- & \- & \text { Ge } \\ \- & \- & \- & \- & \text { B } \\ \text { Semimetal } & \- & 3 & \- & \- \\ \- & \text { VIIA } & 4 & \- & \- \\ \hline \end{array} $$
How many times heavier is a \({ }^{6} \mathrm{Li}\) atom than \(\mathrm{a}{ }^{1} \mathrm{H}\) atom?
When calculating the average atomic mass from percent abundance, you can always quickly check your answer. How?
Complete the following table. $$ \begin{array}{lccc} & \text { Atomic } & \text { Mass } & \text { Number of } \\ \text { Isotope } & \text { Number }(Z) & \text { Number }(A) & \text { Electrons } \\ \hline{ }^{31} \mathrm{P} & 15 & \- & \- \\ { }^{18} \mathrm{O} & \- & \- & 8 \\ \- & 19 & 39 & 19 \\ { }^{58} \mathrm{Ni} & \- & 58 & - \end{array} $$
State in words what the following symbolic equation means. $$ \mathrm{CO}_{2}(g)+\mathrm{H}_{2} \mathrm{O}(l) \longrightarrow \mathrm{H}_{2} \mathrm{CO}_{3}(a q) $$
