Use your Periodic Table of elements. The number to the top left of each atom (its 'atomic number') is also the number of protons in the atom's nucleus.
In the case of gold (Au), that number is 79.

What element is produced when a gold nucleus loses a proton?
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.
Is golds atomic number 79?
mass number is simply the addition of the proton number and neutron number. we also know that proton number of the element is similar to atomic number. we also know that 79 + (197-79) is the no. of neutron no. of the gold. hence when atomic no. of the gold is 79 its atomic mass or mass number is 197.
What element is produced when a gold nucleus gains a proton?
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).
When a mercury-202 nucleus is bombarded with a neutron a proton is ejected. What element is formed?
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.
What is the proton number also called?
The proton number is the atomic number.
Which results in a more highly valued atom adding or subtracting a proton from a gold nucleus?
Adding a proton to a gold nucleus would result in a more highly charged and thus more highly valued atom. This would change the element from gold to a different element with a higher atomic number, potentially leading to different chemical and physical properties.
Is gold a proton?
Gold is NOT a proton. It is an element found in the Periodic Table, with the symnol 'Au' (Aurum ; Latin for Gold). However an atom of Gold contains 79 protons, 79 electrons 118 neutrons. It has an atomic mass of 197. (79 + 118 = 197)
What is the formula for 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
What element has one less proton than Argon?
Thallium (Tl) has one more proton then mercury (Hg), mercury has 79 protons, Thallium has 80 protons.
What is the proton number of iron?
iron has 26 protons
What is the atomic number to a proton?
We don't use a atomic number for a proton. But atomic number is the number of protons an atom contains.
How do you calculate avogadro's number?
1 / mass of a proton = avogadro's number 1 / mass of a proton = avogadro's number
