An unknown element is shiny and is found to be a good conductor of electricity. What other properties would you predict for it?
It seems to be a metal so all classic properties of metals should apply.

Suppose element X is a poor conductor of electricity and breaks when hit with a hammer. Element Z is a good conductor of electricity and heat. In what area of the periodic table does each element most likely belong?
Metals are good conductors of electricity and heat. the text doesen't tell anymore and Z may be one of abaut 90 known metals, in the left area of . X,...

Which are more malleable: metals or nonmetals?
Malleability, the ability of a material to be hammered out into a sheet (from the Latin, $"malleus, hammer"$, is a fundamental property of metals. Solid non-metals, e.g. diamond, sulfur, iodine,...

Why are metals malleable, and ductile, and conductive of heat and electricity?
$"Metallic bonding"$ results from the close packing of metal atoms, such that the atoms contribute a few of their to the overall lattice. These are delocalized, and not associated with...

What metal is the best conductor of electricity?
One way to assess conductivity, is to look up resistivity , which is a physical property of the substance that shows it tendency to resist the flow of electricity. The...

What metalloids are malleable?
Apparently none. Malleability is a property of metals, a result of the between atoms of the metal. I suspect it is closely related to ductility, the ability of a substance...

Which type of bonding is present in a sample of an element that is malleable?
is an electrostatic bond between metal cations and delocalised electrons. Since the metal atoms are in layers on top of each other, these layers can move over another and...

Why are metals malleable and ductile?
In a metallic bond, each metal atom is conceived to donate one or two or more to the bulk lattice. The result is commonly described as $"metallic bonding"$, $"positive ions...

What type of substance is soft, has a low melting point, and is a poor conductor of heat and electricity?
have low forces of attraction between their molecules (i.e. one H2O molecule isn't as attracted to another H2O molecule than the oppositely charges ions are in an ionic compound)....

A compound is broken down into 34.5 g of element A, 18.2 g of element B, and 2.6 g of element C. What is the percent (by mass) of each element?
$%A$ $=$ $(34.5*g)/(34.5*g+18.2*g+2.6*g)xx100%=62.3%$ $%B$ $=$ $(18.2*g)/(34.5*g+18.2*g+2.6*g)xx100%=33.0%$ $%C$ $=$ $(2.6*g)/(34.5*g+18.2*g+2.6*g)xx100%=4.70%$ That is $%" element"$ $=$ $"Mass of element"/"Mass of compound"xx100%$ $"Mass of compound"$ is clearly the SUM of the constituent ....
