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.

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 is the proton number also called?
The proton number is the atomic number.
What is the proton number called when referring to the periodic table?
Proton number is called atomic number when referring to periodic table. Proton number is equal to atomic number.
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.
Which results in a more highly valued atom adding or subtracting a proton from a gold nucleus?
Subtracting a proton from a gold nucleus makes the atom a platinum atom.
The atomic number of an element determines its?
The atomic number of an element is determined by the number of protons in its nucleus.
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
