What are the 3 types of metals?

There are three main types of metals ferrous metals, non ferrous metals and alloys.

Is P metal or nonmetal?

Nonmetals include the nonmetal group, the halogens, and the noble gases. These elements have similar chemical properties to each other that distinguish them from the elements that are considered metals….List of Nonmetals.

NUMBER	SYMBOL	ELEMENT
15	P	Phosphorus
16	S	Sulfur
17	Cl	Chlorine
18	Ar	Argon

What are the 17 nonmetals?

Seventeen elements are generally classified as nonmetals: most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).

Is Diamond a metal or nonmetal?

Carbon is a solid non-metal element. Pure carbon can exist in very different forms. The most common two are diamond and graphite….Diamond and graphite.

Diamond	Graphite
Transparent and colourless	Opaque and black
Hard	Soft

Which is the hardest metal?

tungsten

Is diamond the hardest metal?

The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.

Is diamond a conductor?

Unlike most electrical insulators, diamond is a good conductor of heat because of the strong covalent bonding and low phonon scattering. Thermal conductivity of natural diamond was measured to be about 2200 W/(m·K), which is five times more than silver, the most thermally conductive metal.

Can you shatter a diamond?

As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. This makes the diamond incredibly hard and is why it is able to scratch any other material.

Is silver the best conductor of electricity?

“Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity.

Which metal is the poorest conductor of electricity?

Bismuth and tungsten are two metals which are poor conductors of electricity.

What are insulators give 5 examples?

Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air.

What is the least conductive metal?

mercury

What metal has the highest conductivity?

Silver
