The three most general elemental groups are nonmetals, semimetals, and metals. The characteristics you've described fit the "metals" group of elements.
A metal
Cu2+
any element that is a non metal will do
Element A and element B are the most likely to have similar properties because they belong in the same family, because if you know an element's family you can tell the number of valance electrons and the elements they react with. In periods, the properties are not alike, they slowly change in a pattern.
Be
Of course, iron.
Metals conduct heat and electricity well.
tin and lead
- It is not a ductile metal or- It is not a metal
That depends on the use. For some purposes, pure gold is good, since it conducts electricity very well and does not corrode. For other uses, such as in thin earrings etc., it is often preferable to mix the gold in an alloy, since it is so malleable that it is likely to lose the original shape.
No, I wouldn't. It is more like a insulator, not a conductor. Silver conducts electricity the best. If a current were put through cardboard, it would most likely catch on fire, not conduct electricity.
An element that is shiny, is ductile (easily pulled into wires), is malleable (easily hammered into thin sheets) and conducts electric current and heat is likely to be a metal.You could pick almost any metal and it would fulfill these requirements. Some of the best matches would be gold, silver and copper. Other examples include platinum and lithium. Note that the metallic properties of metals are variable, and some metals have more metallic character than others.
Several metals are very malleable.
Diamond,Silver and Copper.
Malleable is a characteristic of metals as is being ductile and sonorous.Malleable means being able to be beaten into a shape. Ductile means being able to be drawn into wires. Sonorous means ringing like a bell when struck.Metals also conduct electricity and heat.
copper
metallic
in humid weather there is presence of water particles and water does conducts electricity,therefore easy to get an electric shock,unlike in dry weather where there is no conduction of electricity
