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. Submit Answer Retry Entire Group 2 more group attempts remainin. 2019-07-03 In Groups 4A-6A, there are several elements whose symbols begin with S. Name these elements, and for each one give its symbol, atomic number, group number, and period. Describe each as a metal, metalloid… Arsenic is a poisonous metalloid that is found in two main allotropic forms: a metallic gray form, and a nonmetallic yellow form. The name of the element is derived from the Greek word arsenikon , the name for the arsenic-containing mineral orpiment.

Metalloids. are better conductors than nonmetals, but not as good as metals. are used as semiconductors and insulators. Metalloids may either gain or lose electrons during chemical reactions.

Metalloid azoles frequently show expected properties, especially if not too many heteroatoms are present. Thus Grignard reagents prepared from halogen–azoles (see Section 4.02.3.9.3) show normal reactions, as in Scheme 60. 2-Lithioimidazoles react normally, e.g. with acetaldehyde (Scheme 61) 〈70AHC(12)103〉; 5-lithioisothiazoles (see Scheme 62) 〈72AHC(14)1〉 and 2-lithiothiazoles Tellurium is a metalloid; it has a characteristic metallic luster, but can be pulverized to form a gray powder. The name of the element is derived from the Latin word for the Earth, tellus.

Group 1 elements generally have a charge of +1 when they form ions, Group Solution: a) The symbol and atomic number of the heaviest alkaline earth metal are Ra and 88 b) The symbol and atomic number of the lightest metalloid in Group 4A(14) are Si and 14 c) The symbol and atomic mass of the coinage metal whose atoms have the fewest electrons are Cu and 63.55 amu. The Representative Elements Group 4A – The Carbon Group Ø Is named for the nonmetal Carbon Ø Elements in this family have 4 valence electrons Ø Lose their valence electrons to form a +4 charged ion or can gain 4 electrons and form a –4 charged ion.
