The part of the atom that is involved in chemical changes is A. electron. The electrons that are in the most outer shells are called valence electrons which are easily removed or shared to form bonds. Valence electrons are related to the number of valence electrons
Explanation:
Atoms of metals do not hold their electrons to themselves. Instead they allow them to float around them delocalised. This is important because it is this characteristic that allows metals to be good conductors of electricity since electrons are free to move around to carry a charge.

Answer : It takes time to produce 3 g of aluminium is, 165 seconds.
Explanation :
As we are given that the mass of aluminium is, 3 grams. Now we have to calculate the total mass of aluminum.
Total mass of aluminum = 3g × 24 = 72 g
Now we have to calculate the moles of aluminum.

Molar mass of Al = 27 g/mol

As, 1 mole of Al has 3 Faradays
So, 2.67 mole of Al has =
Faradays
and,
Charge = 
Current = 
Now we have to calculate the time.

Hence, it takes time to produce 3 g of aluminium is, 165 seconds.
