Answer: Option (C) is the correct answer.
Explanation:
Metals are the substances which lose electrons in order to gain stability.
Some properties of metals are as follows.
- Usually metals are hard in nature.
- Metals are malleable and ductile in nature.
- Metals are good conductors of heat and electricity.
Gold (Au) is a metal but bromine (Br) is a non-metal.
Boron (B) is a metal but iodine (I) is a non-metal.
Both phosphorous (P) and Selenium (Se) are non-metals.
Tin (Sn) is a metalloid and it shows properties of both metals and non-metals. Also, silver (Ag) is a metal.
Therefore, both tin and silver are good conductors of heat and electricity and shiny when solid.
Thus, we can conclude that out of the given options Sn and Ag two elements are most likely good conductors of heat and electricity and shiny when solid.
