Question 1

What is the most reactive metal in the periodic table?

Accepted Answer

The most reactive metal in the periodic table is Potassium (K). It is highly reactive due to its low ionization energy and high reactivity with water, resulting in the release of hydrogen gas.

Question 2

Which metal is used in the production of aluminum?

Accepted Answer

Bauxite, a type of aluminum ore, is refined to produce pure aluminum. However, the refining process involves the use of electrolysis, where aluminum is extracted from the ore using an electric current. The electrolysis process requires a metal anode, which is typically made of carbon or graphite, bu

Question 3

Which of the following metals is a good conductor of electricity?

Accepted Answer

Metals are generally good conductors of electricity due to the presence of free electrons in their atoms. Among the given options, Copper (Cu) is a well-known conductor of electricity and is widely used in electrical wiring and circuits.

Question 4

Which of the following metals is used in the production of batteries?

Accepted Answer

Lithium (Li) is a key component in the production of lithium-ion batteries, which are widely used in portable electronics and electric vehicles.

Question 5

Which metal reacts most vigorously with cold water?

Accepted Answer

Sodium reacts very vigorously with cold water, producing sodium hydroxide and hydrogen gas. The reaction is highly exothermic and can be explosive. Other metals like iron, copper or gold do not react noticeably with cold water.
