What is the symbol of an ion with 16 protons, 18 neutrons, and 18 electrons? What is the symbol for an ion that has 16 protons, 16 neutrons, and 18 electrons?
The formulas and common names for several substances are given below. Give the systematic names for these substances. a. sugar of lead \(\mathrm{Pb}\left(\mathrm{C}_{2} \mathrm{H}_{3} \mathrm{O}_{2}\right)_{2}\) \(\begin{array}{ll}\text { b. blue vitrol } & \mathrm{CuSO}_{4}\end{array}\) c. quicklime \(\mathrm{CaO}\) d. Epsom salts \(\mathrm{MgSO}_{.}\) e. milk of magnesia \(\quad \mathrm{Mg}(\mathrm{OH})_{2}\) f. gypsum \(\mathrm{CaSO}_{4}\) \(\mathrm{g}\). laughing gas \(\mathrm{N}_{2} \mathrm{O}\)
Distinguish between the following terms. a. molecule versus ion b. covalent bonding versus ionic bonding c. molecule versus compound d. anion versus cation
In an experiment it was found that the total charge on an oil drop was \(5.93 \times 10^{-18} \mathrm{C}\). How many negative charges does the drop contain?
The designations IA through 8 A used for certain families of the periodic table are helpful for predicting the charges on ions in binary ionic compounds. In these compounds, the metals generally take on a positive charge equal to the family number, while the nonmetals take on a negative charge equal to the family number minus eight. Thus the compound between sodium and chlorine contains \(\mathrm{Na}^{+}\) ions and \(\mathrm{Cl}^{-}\) ions and has the formula \(\mathrm{NaCl}\). Predict the formula and the name of the binary compound formed from the following pairs of elements. a. \(\mathrm{Ca}\) and \(\mathrm{N}\) e. \(\mathrm{Ba}\) and \(\mathrm{I}\) b. \(\mathrm{K}\) and \(\mathrm{O}\) f. \(\mathrm{Al}\) and Se c. \(\mathrm{Rb}\) and \(\mathrm{F}\) g. Cs and P d. \(\mathrm{Mg}\) and \(\mathrm{S}\) h. In and \(\mathrm{Br}\)
