Question

Give the difference between metals, nonmetals and metalloids

Answer 1

Answer:

Hey mate!!! ✨✨

Here's your answer...❤❤

Metals: They are sonorous , melleable , ductile and good conductors of heat and electricity. They generally have high melting and boiling points.

Eg: Gold , silver , etc.

Non-metals: They are non-sonorous , non-ductile and poor conductors of heat and electricity. They generally have low melting and boiling points.

Eg: Potassium , calcium , etc.

Metalloids: They have some properties of matals and some properties of non-metals.

Eg: Boron , silicon , etc.

Hope it helps you...

Answer:

Difference between metals, nonmetals and metalloids:

Definition

Metals: Metals are elements having the highest degree of metallic behavior.

Nonmetals: Nonmetals are elements showing less or no metallic properties.

Metalloids: Metalloids are elements having a low degree of metallic behavior.

Position in the Periodic Table

Metals: Metals are found in the left side of the periodic table.

Nonmetals: Nonmetals are found in the right side f the periodic table.

Metalloids: Metalloids are found in the middle of the periodic table.

Block in the Periodic Table

Metals: Metals are located in s, p, d and f blocks.

Nonmetals: Nonmetals are found in s and p blocks.

Metalloids: Metalloids are found in p block.

Appearance

Metals: Metals have a shiny appearance.

Nonmetals: Nonmetals have a dull appearance.

Metalloids: Metalloids have a dull or shiny appearance.

Malleability and Ductility

Metals: Metals show malleability and ductility.

Nonmetals: Nonmetals do not show malleability and ductility.

Metalloids: Metalloids do not show malleability and ductility.

Thermal and Electrical Conductivity

Metals: Thermal and electrical conductivity of metals is very high.

Nonmetals: Thermal and electrical conductivity of nonmetals is very low.

Metalloids: Thermal and electrical conductivity of metalloids is good but less than metals.

Electronegativity

Metals: Metals have a very low electronegativity.

Nonmetals: Nonmetals show a very high electronegativity.

Metalloids: Metalloids have an intermediate value of electronegativity.
