Question

Think and answer
1. The atoms of gold are different from the atoms of silver. True or false? Give reason.
2. Why are noble gases monoatomic?
3. What is the benefit of representing a substance by its chemical formula?
4. The chemical formulae of two compounds can be same. Do you agree?​

Answer 1

1. The atoms of gold are different from the atoms of slicer because the atomic no. of gold is 79 and the atomic no. of the sliver is 47.

2.Noble gases are monoatomic because they have complete octet (apart from Helium, which has duet) , hence they are highly stable on their own and do not react with others to form compounds in standard temperature and pressure conditions.

3.the molecule formula tell the actual number of atoms for each element that is present in a compound. the structural formula,show the actual number of atoms of elements and also gives us the special arrangement of the atoms and which atoms are bonded to each other .

4.Yes, I agree the chemical formulae of two compounds can be the same. The chemical formula is a way to represent the chemical name. The numbers and letters together considered as a chemical formula. It is related to the chemical nam
