12 Questions
Metals are poor conductors of heat and electricity because they have free electrons.
False
Lead is one of the best conductors of heat among metals.
False
Iridium and osmium have low densities compared to other metals.
False
Tungsten has the lowest melting and boiling points among metals.
False
Metals tend to gain electrons (i.e., be reduced) when they undergo chemical reactions.
False
Alkali metals always have a 2+ charge in chemical reactions.
False
All elements that form positive ions by gaining electrons during chemical reactions are called METALS.
False
Mercury is the only metal that is liquid at room temperature.
False
Metals have the ability to reflect light from their surface and can be polished.
True
All metals are malleable and can be pounded into thin sheets known as foils.
False
Metals can be drawn into wires, an example being 100 grams of silver drawn into a 200-meter long wire.
True
All metals are hard except for sodium and potassium which are soft and can be easily cut with a knife.
True
Test your knowledge about metals, metal crystal structure, and specific metal properties such as electrical conductivity and heat conduction. Learn about elements that form positive ions by losing electrons during chemical reactions and their characteristics like bright luster and hardness.
