Dec 13, 2010 · -Metalloid elements will form amphoteric oxides (both acidic and basic oxides). In general, from groups that do not include group 1, 2 or the transition metals, metallic character becomes very relevant down the periodic table. Thus, in group 5A, the most basic oxide would arise from the element with most metallic character. A student is given samples of three elements, X, Y, and Z, which could be an alkali metal, a member of Group 4A, or a member of Group 5A. She makes the following observations: Element X has a metallic luster and conducts electricity. It reacts slowly with hydrochloric acid to produce hydrogen gas. The physical differences between men and women provide functional advantages and have survival value. Men usually have greater upper body strength, build muscle easily, have thicker skin, bruise less easily and have a lower threshold of awareness of injuries to their extremities. The valency electrons of Group A elements is given by the group number. Group A metals lose their valency electrons so the charge of the ion is + and equal to the group #. For example, beryllium is in Group 2A and the ion is Be 2+. Group A nonmetals gain electrons to add to their valency electrons to gain an octet The definition, (used, especially before a noun, with a specifying or particularizing effect, as opposed to the indefinite or generalizing force of the indefinite articlea or an): the book you gave me; Come into the house. Linking Verbs.
