The remaining elements of the group are metals, but their oxides and hydroxides change characters. the most metallic element in period 3 potassium. Xenon sodium bismuth boron the metal in group 15 (5A) the metalloid in group 13 (3A) the gas in group 16 (6A) . The Group 5A elements have the valence shell electron configuration: ns2np3.
. d. The Nitrogen family, the Carbon family and the Boron family are found in the p- block of the Periodic Table. The Nitrogen family is group 13, while the Carbon Group 5a elements are called Pnictogens. It includes nitrogen (N), phosphorus (P ), arsenic (As), antimony (Sb), and bismuth (Bi).
On the periodic table, the elements colored yellow, which generally border the stair-step line, are considered to be metalloids. Notice that aluminum borders the line, but it is considered to be a metal since all of its properties are like those of metals.
A metalloid is a chemical element that exhibits some properties of metals and some of nonmetals. In the periodic table metalloids form a jagged zone dividing elements that have clear metallic properties from elements that have clear nonmetallic properties. Definition for metalloids: elements with properties intermediate between metals and

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.

Group 13. Group 13 contains the metalloid boron and the metals aluminum, gallium, indium, and thallium. The lightest element, boron, is semiconducting, and its binary compounds tend to be covalent and not ionic. The remaining elements of the group are metals, but their oxides and hydroxides change characters.

Give The Symbol For An Element That Is A Metalloid. A Non-metal In Group 4A, 5A, Or 6A.
Its origin lies in attempts, dating from antiquity, to describe metals and to distinguish between typical and less typical forms. It was first applied to metals that floated on water ( lithium , sodium and potassium ), and then more popularly to nonmetals . 1.The metalloids that are included in Group 15 are antimony (Sb) and A)atomic mass B)molar mass C)number of neutrons per atom D)number of protons per atom 2.All elements on the modern Periodic Table are arranged in order of increasing A)Na B)Mg C)Al D)Si 3.Which of the following Period 3 elements has the least metallic character? 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.

The metalloids are a group of elements in the periodic table. They are located to the right of the post-transition metals and to the left of the non-metals. Metalloids have some properties in common with metals and some in common with non-metals.
Germanium (Ge): Atomic number 32. Arsenic (As): Atomic number 33. The elements commonly classified as metalloids are boron, silicon, germanium, arsenic, antimony and tellurium. The status of polonium and astatine is not settled.
Favorite Answer. a) Phosphorus (P) - It is the only one fitting your criteria. b) Radon (Rn) - It is the last of the six noble gases, i.e., helium, neon, argon, krypton, xenon, radon. c) Arsenic (As) - It is the first metalloid in the periodic table.
Group 4A contains a nonmetal (carbon), 2 metalloids (silicon and geranium), and 2 metals (tin and lead).
Carbon is a typical nonmetal. The remaining elements of the group, silicon and germanium, are examples of semimetals or metalloids. Tin and lead form the stable divalent cations, Sn 2+ and Pb 2+, with oxidation states two Although tellurium(VI) compounds are known (for example, TeF 6), there is a marked resistance to oxidation to this maximum group oxidation state.
