3-27 Answer true or false.
(a) For Group lA and Group 2A elements, the name of the ion each forms is simply the name of the element followed by the word ion; for example, Mg is named magnesium ion.
(b) W is named hydronium ion, and W is named hydride ion.
(c) The nucleus of H consists of one proton and one neutron.
(d) Many transition and inner
(e) In naming metal cations with two different charges, the suffix-ous refers to the ion with a charge of +1 and _ic refers to the ion with a charge of +2.
(f) Fe32 may be named either iron(III) ion or ferric ion.
(g) The anion derived from a bromine atom is named bromine ion.
(h) The anion derived from an oxygen atom is named oxide ion.
(i) HCO3- is named hydrogen carbonate ion.
(j) The prefix bi- in the name “bicarbonate” ionindicates that this ion has a charge of −2.
(k) The hydrogen phosphate ion has a charge of +1, and the dihydrogen phosphate ion has a charge of +2.
(l) The phosphate ion is PO34-.
(m) The nitrite ion is NO2, and the nitrate ion is NO3.
(n) The carbonate ion is CO, and the hydrogen carbonate ion is HCO3-.

(a) Draw Lewis structures for each of these diatomic elements. (b) Which diatomic elements are gases at room temperature? Which are liquids? Which are solids?arrow_forward2-67 Account for the fact that the first ionization energy of oxygen is less than that of nitrogen.arrow_forward

(a) Calcium oxide; CaO2 (b) Lithium oxide; LiO (c) Sodium hydrogen phosphate; NaHPO4 (d) Ammonium nitrate; NH4NO3arrow_forward3-22 Why is Li- not a stable ion?arrow_forward3-119 Perchloroethylene, which is a liquid at room temperature, is one of the most widely used solvents for commercial dry cleaning. It is sold for this purpose under several trade names, including Perciene®. Does this molecule have polar bonds? Is it a polar molecule? Does it have a dipole?arrow_forward
- 2-64 Consider the elements B, C, and N. Using only the Periodic Table, predict which of these three elements has: (a) the largest atomic radius. (b) the smallest atomic radius. (c) the largest ionization energy (d) the smallest ionization energyarrow_forward3-77 Ozone, O3, is an unstable blue gas with a characteristic pungent odor. In an ozone molecule, the connectivity of the atoms is OOO and both OO bonds are equivalent. (a) How many valence electrons must be present in an acceptable Lewis structure for an ozone molecule? (b) Write two equivalent resonance contributing structures for ozone. Be certain to show any positive or negative charges that may be present in your contributing structures. By equivalent contributing structures, we mean that each has the same pattern of bonding. (c) Show by the use of curved arrows how the first of your contributing structures may be converted to the second. (d) Based on your contributing structures, predict the OOO bond angle in ozone. (e) Explain why the following is not an acceptable contributing structure for an ozone molecule:arrow_forward
