The table shows some melting temperatures for different metal alloys.Alloys are metallic mixtures composed of two or more elements.Identify which metals are alloys.Metals A and C are alloys.Metals B and C are alloys.Metals A and D are alloys.Metals B and D are alloys.

A chemist is trying to identify a sample of metal that is listed in this table. She passes an electrical current through the sample and finds that, of the metals listed in the table, it’s one of the best conductors. Then she heats the metal to 1000°C, which is the highest temperature her heater allows. The metal doesn’t melt. Which type of metal does the chemist have?Material Melting Point (°C) Electrical Conductivity Rankingaluminum 660 3copper 1085 2zinc 420 4silver 962 1nickel 1455 5 A. aluminum B. copper C. zinc D. silver E. nickel

An alloy could be created from which of the following combinations:I.   metal + different metalII.  non-metal + different non-metalIII. metal + non-metalIV. metal + same metal

Which one of the following is the definition of the key word alloy?An alloy is a metal that contains only one type of metal atom.An alloy is a mixture of metal atoms and atoms of another metal or non-metal element.An alloy is a substance that contains more than one type of element or compound.An alloy is a substance that contains only one type of element or compound.

A and B are two alloys of gold and copper prepared by mixing metals in ratios 7 : 2 and 7 : 11 respectively. If equal quantities of the alloys are melted to form a third alloy C, the ratio of gold and copper in C will be?Options7 : 55 : 99 : 55 : 7

Which is the main type of element found in the upper right part of the periodic table?A.MetalloidsB.Representative metalsC.MetalsD.Nonmetals
