An element that is malleable, ductile, and a good conductor of heat and electricity would be classified as a
a)metalliod
b)semimetal
c)metal
d)nonmetal
c - Metal
Those above are all the properties that distinguish a metal from a non-metal...they are all properties of a metal.
The element that is malleable, ductile, and a good conductor of heat and electricity would be classified as a metal (c). Metals generally have these characteristics, making them suitable for applications such as electrical wiring, heat transfer, and various other industrial uses.
To determine the classification of an element based on its properties, you can refer to the periodic table. The given properties of an element as being malleable (able to be hammered into thin sheets without breaking), ductile (able to be drawn into wires), and a good conductor of heat and electricity suggest that it is a metal.
To confirm this, you can look at the periodic table, which classifies elements based on their properties. Metals are generally found on the left side and in the middle of the periodic table. Nonmetals are found on the upper right side, metalloids are located along a diagonal line, and semimetals have properties between metals and nonmetals.
Therefore, based on the properties given and the general location of metals on the periodic table, the correct classification for an element with the described properties is (c) metal.
