Question

What are the chemical properties of non metals?​

Answer 1

Properties of Non-metals:-

• They aren't lustrous. They do not reflect light well. (Graphite, iodine)
• They possess a low specific gravity.
• They are neither malleable, nor ductile.
• They are poor conductors of heat and electricity.
• They form poly-atomic molecules.
• They are brittle; they break into small pieces when hammered.
• They are non-sonourous; the do not produce any sound when struck.

More Information:-

Non-metals are elements are lack positive charge on them. Among the known elements, 21 elements are non-metals.

Eg:- chlorine, bromine, hydrogen, helium, etc.

What are the chemical properties of non metals?

Explanation:

‌$\huge\fbox\red{Answer♡}$

• Nonmetals are poor conductors of heat and electricity. Graphite and Gas carbon are exceptions.
• Unlike metals, nonmetals aren’t malleable and ductile.
• Nonmetals react more with metals than with nonmetals.
• Usually, nonmetals react with other nonmetals in high temperature.
• Most nonmetals do not react with air in room temperature.
• White phosphorus is the only nonmetal that reacts with air to form its oxide by burning.
• Nonmetals have a low density.
• They do not form alloys. However, nonmetals like carbon, silicon and phosphorous.
• Nonmetals exist in all states of matter at room temperature.
• Different nonmetals have different reactions.
• Chlorine is the most reactive metal in the halogen family i.e. Chlorine (Cl), Bromine (Br), Iodine (I), and Fluorine (F). The reactivity order of the halogen family is Cl > Br > I.
• Therefore, Chlorine (Cl) can displace Bromine (Br) and Iodine (I) from solutions of bromides (NaBr) and Iodides (NaI).
• Ionic solids are formed when nonmetals with high electronegativity react with alkali and alkaline earth metals.
