The atomic number of gold is 79 how many neutrons are there in an atom of gold that has atomic mass of 197 amu how you got your answer
What is 197-79?
197-97=118
To find the number of neutrons in an atom of gold, you need to subtract the atomic number (which represents the number of protons) from the atomic mass.
The atomic mass of gold is given as 197 amu, and the atomic number is 79. The atomic mass represents the combined mass of protons and neutrons in the nucleus of an atom.
To calculate the number of neutrons, subtract the atomic number (protons) from the atomic mass:
Number of neutrons = Atomic mass - Atomic number
= 197 amu - 79
= 118 neutrons
Therefore, an atom of gold with an atomic mass of 197 amu has 118 neutrons.
