Most of the metals are very reactive, they quickly oxidize when exposed to air and form a layer on the metal surface. Magnesium sulfate is a compound, and the terms metal a nonmetal do not apply to it. Answer: A. Group 15 of the periodic table is also called the nitrogen group. It is a brittle material as non-metals. Explanation: i think its b. ... Is mercury a metal nonmetal or metalloid? Magnesium is an alkaline earth metal. Is boron considered a metal or nonmetal? Explanation: Nitrogen is a reactive nonmetal. metal, nonmetal, or metalloid lab Objective: To observe physical and chemical properties of a set of elements and classify the elements according to those properties. Metal oxides are basic and ironic. Metalloids: Metalloid doesn’t have malleable or ductile properties. Using the periodic table, you can classify the elements in many ways. Magnesium is still, however, limited by its extractions costs, which make the metal about 20% more expensive than aluminum. Non-Metals Non-metallic luster (dull) Brittle if it is a solid Non-conductors of heat and electricity, BUT are good insulators. METAL, NONMETAL, METALLOID Hydrogen Magnesium Calcium Arsenic Carbon Helium Lead Aluminum NONMETAL METAL METALLOID * * * Fe, Au, Cu, and Al all solid at room temp- who can think of one metal not solid at room temp?- Mercury! Silicon is a very poor conductor of heat and electricity. which plant has the weakest movement?why? Dim … One useful way is by metals, nonmetals, and metalloids. silicon is a metalloid. metal : metalloid : nonmetal . Can be solid, liquid, or gas at room temperature Metalloid Can be shiny or dull Can be malleable or brittle. No light. The elements can be classified as metals ... metal and nonmetals combine to form ionic compounds, while nonmetals combine with other nonmetals to form covalent compounds ... the Group 2A metals such as magnesium and calcium form 2+ charges, and the Group 3A metals such as aluminum form 3+ charges. Mendeleev's periodic table was organized by: atomic weight. The first element in the group is the nonmetal nitrogen (N), followed by phosphorus (P), another nonmetal. Partially conduct heat and electricity. Please classify the following if it's metal, nonmetal or metalloid... a. argon b. silver c. magnesium d. radon 1 See answer kennedycabison21 kennedycabison21 i think its silver. Yes, magnesium is a metal, Moreover, Magnesium is a chemical element with symbol Mg and atomic number 12. Related Facts. The periodic table is organized in families and periods. Metals In the periodic table, you can see a stair-stepped line starting at Boron (B), … a diagonal division on the periodic table that divides the metals from the nonmetals and along which lay the metalloids. Then, is Phosphorus a metal or nonmetal or metalloid? Yes, magnesium is a metal, Moreover, Magnesium is a chemical element with symbol Mg and atomic number 12. read more. New questions in Science. Is sodium a metal or nonmetal? Is carbon a metal, a nonmetal or a metalloid? Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. Due to import tariffs on Chinese-produced magnesium, US magnesium prices can be almost double that of aluminum. That leaves A or C, neon is a noble gas, the rest make sense too.
