Which of the following is an example of matter? ‘ (d) Lead. • But it can be found in solid forms. Therefore, it is classified as a transition metal because it falls into our box. Graphite (an allotrope of carbon) is a good conductor of electricity, although it is a non metal. Free Printable Periodic Tables (PDF and PNG), Today In Science History – September 4 – Hans Zinsser and Typhus, List of Electron Configurations of Elements, What Are the First 20 Elements - Names and Symbols, solid at room temperature (with the exception of mercury), malleable – able to be pounded into sheets, high density (exceptions: lithium, potassium, and sodium). In chemistry, a metal is an element that readily forms positive ions (cations) and has metallic bonds. 3. All materials shown property of malleability expect a. 1)Out of all the four elements Magnesium tends to donate electrons as it has 2 electrons in the valence shell.So it is a metal whereas chlorine is a non-metal and silicon is non-metal. Which of the following is an example of a chemical property of matter? Which of the following properties of metals makes this possible? SURVEY . If you are having trouble with Chemistry, Organic, Physics, Calculus, or Statistics, we got your back! The following is a characteristic of a metal: Conducts heat readily. a. Metals such as K, Na, Ca, Mg and Al, that are reactive or at the top of the electrochemical series, are extracted from the electrolysis of fused compounds. d. Metals … The boundary between metals and metalloids is not well defined and varies depending on who you ask. Ask for details ; Follow Report by Aliadrot 3 weeks ago Log in to add a comment C. Lead. Base metals are any nonferrous (they contain no iron) metals that are neither precious metals nor noble metals. Cyanide process is a technique for extracting gold/silver from low-grade ore by converting the gold/silver to a water soluble coordination complex. To her surprise it acquired a dull green coating after a couple of months. Ge is a metalloid in group 14. Type # 5. Metals are ductile. - 26379676 Q: Only 2 elements are liquid at room temperature?
