Even though they look very different, oxygen and sulfur share some similar properties. When metal atoms share their outermost electrons with a nonmetal, the metal and nonmetal become _____. Many metals are "dull grey"; an example is niobium. Tags: Question 11 . 7.31 g/cm3. There are several properties that make most elements metals. Sn. These metals often have a shiny luster and conduct both heat and electricity very well. Nonmetals are gases or are dull, brittle, and poor conductors of heat and electricity. Alkali earth metals are less reactive than the alkali metals. Metalloids are generally semiconductors. 6 months ago. Metals are further classified as basic metals, transition metals, alkali metals, alkaline earth metals, lanthanides (rare earth elements), and actinides. Solid elements described as dull, brittle, and poor electrical and thermal conductors are most likely known as METALS. Do you agree or disagree? Element Category: Post-transition metals. periodic law: properties of the elements are periodic function of their atomic numbers. Thermal conductivity is the ability of an element to transfer _____ answer choices . Heat and electricity travel easily through metals, which is why it is not wise to stand next to a flagpole during a thunderstorm! This means that they can carry an electrical charge under special conditions. Chemically, indium is similar to gallium and thallium. Metals have a high to moderate density whereas non-metals have low to moderate density. Transition Metal. Alkaline Earth Metal. Not all of them, but we are sure you've seen pictures of silver (Ag), gold (Au), and platinum (Pt). None of my students are dull, fortunately!Lead is a soft dull grey metal. Metallic bond in transition metals are formed by the delocalization of unfilled d-orbitals. A thing is either unique or its not you can't have things that are 'most' or 'least' unique.
