Concept explainers
Interpretation:
A mole of silver with a mole of platinum needs to be compared on the basis of protons, neutrons, electrons and atoms.
Concept introduction:
In 1 mole of a substance there are
Answer to Problem 85A
A mole of platinum has more protons, electrons and neutron but the same number of atoms as compared to 1 mol of silver.
Explanation of Solution
In 1 mol of any substance there are
The
The atomic number is equal to the number of electrons and protons. Thus, number of protons and electrons in platinum is 78 and that in silver is 47.
Also, mass number is equal to number of protons and number of neutrons thus, number of neutrons in platinum and silver will be:
Thus, number of protons, electron and neutrons are more in case of platinum but, number of atoms is same as silver.
