Shiny metallic solid unreactive good electrical conduct ductile density 10.5

There are several elements in the Periodic Table that are both malleable and good conductors of electricity and even heat. The Alkali metals such as potassium and sodium from Group 1 of the Periodic Table are very good conductors of electricity and are also pliant and malleable. From the group of Transition metals iron, copper, silver and gold are instances of all the 38 metals of this group that fulfil the conditions of being conductors and malleable. Some metals such as tin, lead, thallium, and aluminium are instances of elements that are malleable and can conduct electricity in the solid form. These elements belong to the Metalloids group in the Periodic Table.

Well technically there are two correct answers b and d. but for you its probably b in general.good day sir/ma'am : ) (i know not gender)
