Questions Related to metals
Metals are usually ________ in nature.
-
soft
-
hard
-
data insufficient
-
none of above
Metals are usually solid in nature. There is less metal that is soft in nature. Some metals are used to make items like coins because they are hard and will not wear away quickly.
Explain lustre.
-
Shining by reflecting light
-
Deformation into thin sheets
-
Deformation into rods
-
Free electrons to conduct electricity and heat
Lustre is the way light interacts with the surface of a crystal, rock, or mineral. There are various types of lustre like greasy lustre, metallic lustre, dull lustre etc.
Are metals sonorous?
-
Yes
-
No
-
Maybe
-
None of above
Sonorous metals mean a deep, full, pleasing and imposing sound. It is one of the physical properties of a metal through which a sound is produced when metal is hit.
Are non-metals malleable?
-
Yes
-
No
-
Maybe
-
None of above
Non-metals are not malleable. They are brittle and hence they break easily. Such non-metals cannot be deformed by a hammer or rolling. Hence, non-metals cannot be deformed to form thin sheets.
Which metal is soft in nature?
-
Sodium
-
Potassium
-
Both A and B
-
None of above
All the metals are hard in nature. However, both sodium and potassium metals are soft and can be cut using a knife. The bonding in these metals is weak and electrons are not located over a single atom but over a number of atoms.
Which of the following is non-malleable?
-
Sulphur
-
Chlorine
-
Xenon
-
None of the above
Sulphur, chlorine and xenon, all are $p-$block elements.
Most metals are hard except _______ and _________.
-
radium, nitrogen
-
sodium, potassium
-
osmium, carbon
-
copper, iron
Most metals are hard except sodium and potassium. They can be easily cut with a knife. Osmium is hard enough to scratch glass.
Which of the following is not malleable?
-
Sulphur
-
Selenium
-
Phosphorus
-
All of the above
Non-metals are not malleable. They are brittle and hence they break easily. Such non-metals cannot be deformed by a hammer or rolling. Hence, non-metals cannot be deformed to form thin sheets.
Which of the following non-metal can be malleable?
-
Sulphur
-
Phosphorus
-
Nitrogen
-
Graphite
Graphite is a non-metal consisting of 3 carbon atoms. he weak attractions between the layers of atoms in graphite are easily broken. Therefore, graphite is soft and the layers can slide over each other.
Which among the following will be the softest metal?
-
Sodium
-
Aluminium
-
Iron
-
All of the above
Sodium and potassium are soft metal which can be easily cut with a knife.
