Answer:
The answer to this question is given below in this explanation section.
Explanation:
"What element has conductivity,shiney luster,magnetic
-science"
silicon has a shiny luster,But it is brittle and conducts electricity poorly.Some metalloids change their characteristics when they react with different elements.Luster conductivity and malleability are physical properties can be observed be observed without attempting to change the identity of the substance.The term physical property is an observable characteristics of a substance. in this case the luster conductivity and malleability of metals are the properties, which can be observed by our senses.It differs from chemical properties which can only be observed when the substance change its chemical identity.
Metal are solid at room temperature with the exception of mercury which is liquid at room temperature.Luster metal have the quality of reflection light from its surface and can be polished e.g gold,silver and copper.
