How would the structure of an atom of 202Hg have to be changed for the atom to become an atom of 197Au?

80Hg(202) has 80 p + 122 n
79Au(197) has 79 p + 118 n
This is 1 proton and 4 neutrons less than in Hg

How many neutrons are in 202Hg?
122
What is the percent of abundance of mercury on earth?
Less than 0.01 percent.Mercury's abundance in Earth's crust is 85 parts per billion by weight, 9 parts per billion by moles.The most abundant naturally forming isotope is 202Hg is at 29.86%.
Does the element Mercury contain isotopes?
Mercury has isotopes ranging from an atomic mass of 171 to 210. Of these, only 7 are stable and a further 5 have halflives longer than a halfday. The radioactive isotopes are: 171 to 195, 197, 205 to 210. Two of the stable isotopes also have unstable excited forms.

Does Mercury the elemrnt have any isotopes?
Yes, mercury has 7 known isotopes: 202Hg (30%), 200Hg (23%), 199Hg (17%), 201Hg (13%), 198Hg (10%), 204Hg (7%) and 196 Hg (traces).
Disadvantage of mercury on the earth?
You probably mean "abundance of mercury on Earth". Its abundance in Earth's crust is 85 parts per billion by weight, 9 parts per billion by moles. The most abundant naturally forming isotope is 202Hg is at 29.86%.

How many neutrons does Mercury have in it?
there are 121 neutrons in Mercury This is CORRECT. The number of protons (80) is equal to the number of electrons and it is also the atomic number. You can figure out the number of neutrons by subtracting the atomic weight by the atomic number. For example: Mercury Atomic number: 80 Atomic weight: 201 --> 201 - 80 = 121 which is the number of neutrons BTW this works with all the elements on the periodic table
Why can two atoms of the same element have different numbers of neutrons but must always have the same number of protons?
Since protons are of the same charge, they naturally repel each other within the nucleus, and since they are so close together, the repelling force is enormous. Therefore, the function of neutrons (uncharged particles) is to buffer the forces between the protons. But as atoms increase in size, there are more protons and more neutrons are needed to buffer to protons. The reason for the increase is the spherical nature of the nucleus. And the rest of the story is... that all the neutrons and protons in a nucleus, the nucleons (notice we hit you with another term - nucleon - which means a particle in the nucleus, a neutron or proton) have to undergo a magical transformation when the atomic nucleus is formed. Let's back up. The first post is exactly right. Protons, those little positively charged critters, don't like each other. It's the first law of electrostatics - opposite charges attract and like charges repel. So the protons don't like each other. What happens when any nucleus forms (by fusion or as the result of nuclear decay or by nuclear fission) is that all the nucleons (that term again meaning a proton or neutron) go to Jenny Craig and lose a bit of weight. Actually it's mass, but pretty close to the same thing. This mass is converted to binding energy or nuclear glue. That's what holds the nucleus together. Binding energy. Remember Einstein? Yeah, the genius with the freaky hair. Him. He said matter and energy are the same thing. (And the conversion factor is the square of the speed of light. Wow!) Each nucleon goes on that diet and gets slimmer. It's called mass deficit - the reduction of the mass of a nucleon made as a contribution to the creation of the binding energy necessary to hold the nucleus of an atom together. Are we good? So as heavier and heavier nuclei are formed, the number of those grumpy little protons increases to the point where we have to have progressively more and more binding energy to hold the whole thing together. And the neutrons contribute to that cause. Instant replay: heavier nuclei need progressively more binding energy to hold the nucleus together 'cause the protons (which don't like each other) are getting more grumpy, and more and more neutrons are needed to undergo mass deficit to contribute to increased binding energy to make the whole thing stay together. It's clear what you're thinking. You're thinking, "Hey, there must be a point where we just can't get enough binding energy to glue a super heavy nucleus together." You're right. Absolutely correct.
