  1. The correct option is B Metalloid. In the modern periodic table, a zig-zag line separates metals from non-metals. The border line elements - boron, silicon, germanium, arsenic, antimony, tellurium and polonium - exhibit properties similar to metals and nonmetals and are called metalloids. Suggest Corrections.

  2. alkali. The _______ metals are the most reactive group of elements. hydrogen. __________ is the only nonmetal on the left side of the periodic table. diatomic molecule. consists of two atoms of the same element in a covalent bond. transition element. element in Group 3 through Group 12 of the periodic table.

  3. Jul 12, 2023 · Both the d- and f-block elements react with nonmetals to form binary compounds; heating is often required. These elements react with halogens to form a variety of halides ranging in oxidation state from 1+ to 6+. On heating, oxygen reacts with all of the transition elements except palladium, platinum, silver, and gold.

  4. Ans: The elements which have a tendency to gain electrons are known as non-metals. The tendency to gain electrons increases on moving across a period due to an increase in the nuclear charge and decrease in the atomic size. Hence, the non-metallic character increases across a period. As we move down the group, the non-metallic character ...

  5. Jan 28, 2020 · Elements to the left of the line are considered metals. Elements just to the right of the line exhibit properties of both metals and nonmetals and are termed metalloids or semimetals. Elements to the far right of the periodic table are nonmetals. The exception is hydrogen (H), the first element on the periodic table. At ordinary temperatures ...

  6. Mar 21, 2024 · Metalloids are elements that exhibit both metallic and non-metallic properties. There are six recognized metalloids in the periodic table: boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te). These elements have properties that are intermediate between those of metals and nonmetals.

  7. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: Which of the following elements has both metallic and non-metallic properties? Select one: a. Carbon (C) b. Lead (Pb) c. Helium (He) O d. Antimony (Sb) e. Potassium (K) O. Here’s the best way to solve it.
