The atomic number of Mercury(Hg) is 80; since atomic number of an atom= No. of protons.Thus No. of protons in Mercury is 80.
Also No. of protons = No. of electrons (In an neutral Atom; which is not an ion).Therefore No. of electrons is also 80.
Next, Mass number(Atomic Mass) of Mercury is 160.
Mass Number(Atomic Mass)= No. of Protons + No. of Neutrons.
Hence calculating that we get No. of Neutrons also to be 80.
FYI; Electrons have negligible mass so they are not included in calculating Mass of an atom, which only requires the nucleus which contains only protons and neutrons

∙ 13y agoThe amount of neutrons depends on the mass number that mercury has. Once you do know the mass number, you just subtract the number of protons, 80 (found on the period table) from that number to get the amount of neutrons.
*The mass number is not found on the Periodic Table*

∙ 14y agoThe atomic number of mercury is 80; therefore, each atom has 80 each of protons and electrons. The number of neutrons depends on the isotope, but for Hg-200, the number of neutrons is 200 - 80 = 120.

∙ 9y agoFrom the periodic table, we have mercury's atomic number as 80 and relative atomic mass as 201. So mercury has 80 protons and 80 electrons. The exact number of neutrons a mercury atom would have depends on its isotopic form, but for the most abundant isotope mercury-202 (about 30%), it would have 202 - 80 = 122 neutrons. Else just take 201 - 80 and you will get 121 neutrons as a rough figure.

How many protons and electrons does mercury have?
Mercury (Hg) can ONLY have 80 protons, or else it cannot be mercury. The difference between its mass number (201) and 80 is 121, which is the number of neutrons. These can vary and are called isotopes. The number of protons can always only be 80 for mercury, tho.
How many electrons are present in an atom of mercury 201?
121 neutrons.
How many neutrons are present in Hg?
The number of neutrons in an atom of mercury depends on the isotope. The most common mercury isotope has 122. The average number of neutrons in an atom of mercury is about 120.
Determine the numbers of electrons protons neutrons 80 35 Br?
Number of Protons: 35 Number of Neutrons:45 Number of Electrons:35
An isotope of mercury has 80 protons and 120 neutrons What is the mass number of this isotope?
The sum of the neutrons and protons is the mass number (A)In this problems,the answer for mass number of mercury isotope is:80 protons + 120 neutrons = 200
How many subatomics particles are in mercury?
As all atoms mercury contain protons, neutrons and electrons. Mercury has 80 electrons and protons and a variable number of neutrons - depending on the isotope.

Protons neutrons and electrons for mercury?
portons 80 neutrons 121 electrons 80
How many electrons are present in an atom of mercury 201?
121 neutrons.
Do electrons equal the sum of the number of neutrons and protons in an isotope?
No. The number of neutrons has no affect on the number of protons and electrons.
Why are electrons number the same as neutrons number?
They are NOT. The number of electrons and the number of neutrons are not linked at all - for instance, an atom of Hydrogen has one proton and one electron and NO neutrons.
What are the number of protons neutrons and electrons in an element?
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
How many neutrons are present in Hg?
The number of neutrons in an atom of mercury depends on the isotope. The most common mercury isotope has 122. The average number of neutrons in an atom of mercury is about 120.
What is the protons neutrons and electrons for mercury?
Atomic weight of mercury is 201 80 protons 80 electrons 121 neutrons Mercury has 7 stable isotopes, with 116, 118, 119, 120, 121, 122 and 124 neutrons. The 116 neturon isotope is pretty rare on Earth (0.15%).
What is the number of neutrons electrons and protons in nitrogen14?
there are 7 neutrons, 7 protons, and....----electrons
What are the number of protons neutrons and electrons in boron?
Boron has 5 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a boron isotope = Mass number - 5
