80 protons
When a mercury-202 nucleus is bombarded with a neutron and a proton is ejected, the resulting nucleus will have one less proton than the original mercury nucleus. Mercury (Hg) has an atomic number of 80, so after losing a proton, the new element formed will be gold (Au), which has an atomic number of 79. Thus, the reaction transforms mercury-202 into gold-201.
Thallium (Tl) has one more proton then mercury (Hg), mercury has 79 protons, Thallium has 80 protons.
The proton number is the atomic number.
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons
Of the common sub-atomic particles, both the proton and the neutron have mass numbers of 1.

When a gold nucleus loses a proton, it is transformed into a mercury nucleus. Mercury has an atomic number of 80, one less than gold's atomic number of 79.
When a gold nucleus gains a proton, it becomes a mercury nucleus. This occurs through the process of beta-plus decay, where a proton transforms into a neutron, resulting in a change in atomic number from 79 (gold) to 80 (mercury).
Thallium (Tl) has one more proton then mercury (Hg), mercury has 79 protons, Thallium has 80 protons.

Platinum, Mercury
iron has 26 protons
We don't use a atomic number for a proton. But atomic number is the number of protons an atom contains.
1 / mass of a proton = avogadro's number 1 / mass of a proton = avogadro's number

If you add a proton, neutron, and electron to a gold atom, you would obtain a new element called Mercury (symbol: Hg). This new element would have a different number of protons, neutrons, and electrons compared to gold.
