Which statement best describes the properties of metals?
a) they are shiny and bend without breaking
b) they are dull and are good electrical insulators
c) they conduct electricity well and are brittle
d) they can be flattened and do not conduct heat well

The correct option is A.

Metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. The malleability of metals refers to their ability to withstand bending and hammering without breaking. Metals are not dull, neither are they brittle, those are the properties of non metals.

Answer : The correct statement is, (A) they are shiny and bend without breaking

Explanation :

Metals : Metals are the elements that easily loose electrons and forms cations.

The properties of the metals :

Non-metals : Non-metals are the elements that easily gain electrons to form an anion.

The properties of the non-metals :

Hence, the best statement is, (A) they are shiny and bend without breaking

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
