  1. True

  2. False

Show answer
Correct Option: B
Explanation:

Ans: (B) False

Metals or metals alloys are used to make pen body.
Eg: Aluminium is used in some cases to make the pen body and stainless steel can be used to make pen components.
Precious metals such as gold, silver also used for Expensive pens.

Find the odd one out from the following:
Aluminium, iron, copper, silver, iron, brass, sand and shirt 

chemistry non-metals introduction to non-metals occurence of metals occurrence of metals and non metals

  1. iron and copper

  2. brass and silver

  3. aluminium and sand

  4. sand and shirt

Show answer
Correct Option: D
Explanation:

Ans : (D) Sand and Shirt

Note : Sand $\rightarrow$ it is composition of $SiO _{2}, Al _{2}O _{3}, K _{2}O, ....$ etc. which posses metal properties.
Above all pair posses metal properties except sand and shirt.
Shirt is non-metal (made up of fabric).

Gallium and mercury are

chemistry non-metals introduction to non-metals occurence of metals occurrence of metals and non metals

  1. Liquid non metals

  2. Solid metals

  3. Liquid metals

  4. Solid mettaloids

Show answer
Correct Option: C
Explanation:

Metals exists as solids at room temperature but Gallium and mercury are  liquid metals.
They Exists as liquids at room temparature.
Hence option C is correct.

Which of the following is liquid non metal?

chemistry non-metals introduction to non-metals occurence of metals occurrence of metals and non metals

  1. Bromine

  2. Sulfur

  3. Aluminum

  4. Carbon

Show answer
Correct Option: A
Explanation:

Non metals are generally solids and gases. They do not exist as liquids except Bromine. Bromine is liquid. Hence, option A is correct.

+ Solution

The density of non metals is _____ when compared with metals.

chemistry non-metals introduction to non-metals occurence of metals occurrence of metals and non metals

  1. High

  2. Same

  3. Low

  4. None of the above

Show answer
Correct Option: C
Explanation:

The density of non metals isl ow when compared with  metals as metals are solids and non metals are liquids and gases(Generally solids are more denser than liquids and gases).
Hence option C is correct.

The density of metals is ________ when compared with non metals.

chemistry non-metals introduction to non-metals occurence of metals occurrence of metals and non metals

  1. high

  2. low

  3. same

  4. None of the above

Show answer
Correct Option: A
Explanation:

The density of  metals are high when compared with  non metals as metals are solids and non metals are liquids and gases(Generally solids are more denser than liquids and gases).
Hence option A is correct.

Metals are solid at room temperature except

  1. Mercury

  2. Gallium

  3. both a and b

  4. Sodium

Show answer
Correct Option: C
Explanation:

Metals are solid at room temperature except Mercury  and Gallium. These are liquids at room temparature.
Hence option C is correct.

Non metals exist in:

chemistry non-metals introduction to non-metals occurence of metals occurrence of metals and non metals

  1. solid

  2. liquid

  3. gas

  4. all of the above

Show answer
Correct Option: D
Explanation:

Non-metals are generally solids and gases. They do not exist as liquids except Bromine. Bromine is a liquid non-metal.


Hence option D  is correct.

Iodine is :

chemistry non-metals introduction to non-metals occurence of metals occurrence of metals and non metals

  1. Lustrous non-metal

  2. Sonorous non-metal

  3. Lustrous metal

  4. Malleable metal

Show answer
Correct Option: A
Explanation:

Generally Non metals are not lustrous(not shiny). But Iodine is the only non metal which is lustrous. Iodine is shiny. Hence, option A is correct.

Non metal oxides are:

chemistry non-metals introduction to non-metals occurence of metals occurrence of metals and non metals

  1. Acidic in nature

  2. Amphoteric in nature

  3. Basic in nature

  4. None of the above

Show answer
Correct Option: A
Explanation:

Metal oxides are basic in nature whereas non-metal oxides are acidic in nature.


Non-metal oxides are called acidic oxides because when a non-metal reacts with oxygen, it gives an oxide which on dissolution with water gives an acid.

 Hence, option A is correct.
