2010-12-13 · -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 2018-02-19 · Group 5A (group 15) consists of five elements which are nitrogen, phosphorus, arsenic, antimony & bismuth, Elements of this group are not abundant in nature, except nitrogen which represents about 80 % of atmospheric air (4/5) of air volume, We can’t detect both nitrogen & phosphorus by flame test, because both of them are nonmetals. There are several metals in group 5a of the periodic table. These metals include arsenic, antimony, vanadium, niobium, tantalum, and dubnium. It's in the metalloid group.

Astatine is usually classified as either a nonmetal or a metalloid; metal formation has also been predicted. Physical. Most of the physical properties of astatine have been estimated (by interpolation or extrapolation), using theoretically or empirically derived methods. Group 13. Group 13 contains the metalloid boron and the metals aluminum, gallium, indium, and thallium.
