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.

- ✓ aw the major substitution products you would expect for the reaction shown below. If substitution would not occur at a significant rate under these conditions, check the box underneath the drawing area instead. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but strong heat or reflux is not used.
