Question

What are the characteristics of metals?

Answer 1

Hint: We know that except for hydrogen, all components that form positive particles by losing electrons during reactions are called metals. So, we can consider metals as electropositive components that generally have low ionization energies. We can say that metals are solids under ordinary conditions aside from Mercury.

Complete answer:
We can list some properties of metals as,
Metals are lustrous, moldable, pliable, great conveyors of heat and electricity. Different properties include:
State: Metals are solids at room temperature except for mercury, which is fluid at room temperature (Gallium is fluid on hot days).
Gloss: Metals have the nature of mirroring light from their surface and can be cleaned e.g., gold, silver and copper.
Pliability: Metals can withstand pounding and can be made into meager sheets known as foils. For instance, a sugar 3D shape estimated lump of gold can be beaten into a slight sheet that will cover a football field.
Malleability: Metals can be brought into wires. For instance, $100g$ of silver can be brought into a meager wire around $200$ meters in length.

Additional information:
We can list the other properties of metals as,
Hardness: All metals are hard aside from sodium and potassium, which are delicate and can be cut with a blade.
Valency: Metals ordinarily have $1$ to $3$ electrons in the peripheral shell of their molecules.
Conduction: Metals are acceptable conveyors since they have free electrons. Silver and copper are the two best transmitters of heat and electricity. Lead is the weakest conductor of heat. Bismuth, mercury and iron are additionally poor conductors
Thickness: Metals have high thickness and are exceptionally hefty. Iridium and osmium have the most elevated densities while lithium has the least thickness.
Melting and Boiling Points: Metals have high softening and edges of boiling over. Tungsten has the most noteworthy boiling point and melting point over though mercury has the least. Sodium and potassium likewise have low dissolving points.

Note:
We have to know that our crust of Earth is made up of metallic elements such as aluminum, calcium, potassium, magnesium, and sodium. We have to know that metals generally take the structure of crystalline solids. The chemical reactivity differs from one metal to other metal. Metals such as lithium, potassium are highly reactive whereas silver, palladium, gold, and platinum.
