Metalloids is a chemistry term used to describe a group of chemical elements that share some of the physical and chemical properties of metals, such as iron and copper, but cannot be classified as metals because they also share some of the properties of non-metal elements, such as carbon and sulfur. Transcribed Image Textfrom this Question. Give the symbol for an element that is a metalloid. a non-metal in group 4A, 5A, or 6A. a metal in group 3A or 4A.
As you go down the periodic table, group 4A elements become more metallic, meaning they can be good conductors of heat and electricity, they are malleable (or bendy), and they have a metallic Antimony (Sb) is a chemical element, a metalloid placed in the group 15 and period 5 of the periodic table of Mendeleev. What does Be stand for in the peridic table? Element 4 Beryllium The metals which follow the transition metals (towards the bottom of Groups 4A and 5A) can lose either their outermost s and p electrons, forming charges that are identical to their group number, or they can lose just the p electrons while retaining their two s electrons, forming charges that are the group number minus two. In other words, tin and lead in Group 4A can form either 4+ or 2+ charges, while bismuth in Group 5A can form either a 5+ or a 3+ charge. By far the single largest use of lead is in lead storage batteries. The group 14 elements all have ns 2 np 2 valence electron configurations. All form compounds in which they formally lose either the two np and the two ns valence electrons or just the two np valence electrons, giving a +4 or +2 oxidation state, respectively.
Notice that aluminum borders the line, but it is considered to be a metal since all of its properties are like those of metals. Metalloid azoles frequently show expected properties, especially if not too many heteroatoms are present.

The first element in the group is the nonmetal nitrogen (N), followed by phosphorus (P), another nonmetal . Arsenic (As) (Figure below) and antimony (Sb) are the metalloids in this group, and bismuth (Bi) is a metal . Group 14. The metallic members of group 14 are tin, lead, and flerovium. Carbon is a typical nonmetal.

Metalloid, in chemistry, an imprecise term used to describe a chemical element that forms a simple substance having properties intermediate between those of a typical metal and a typical nonmetal. There is no single property which can be used to unambiguously identify an element as a metalloid. These seven elements were classified as metalloids in the periodic table from the 13th to the 16th group. It was supposed to classify Astatine as either a non-metal or metalloid. The formation of metals has also been expected.
