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

∙ 15y agoThere are different amounts of neutrons in a Mercury neucleus. This is because of the fact that chemical properties of an element are determined by the number of protons, not neutrons - the latter just adds mass. Here are the known isotopes of Mercury: * 194 (114 neutrons) - unstable with half life of 444 years. Decays by beta+ to form Gold-194 * * 195 (115 neutrons) - unstable with half life of 9.913 hours. Decays by beta+ to form Gold-195 * * 196 (116 neutrons) - Stable, accounts for 0.014987% of natural Mercury. * 197 (117 neutrons) - unstable with half life of 64.14318 hours. Decays by beta+ to form Gold-197 * * 198 (118 neutrons) - Stable, accounts for 9.97% of natural Mercury. * 199 (119 neutrons) - Stable, accounts for 16.87% of natural Mercury. * 200 (120 neutrons) - Stable, accounts for 23.1% of natural Mercury. * 201 (121 neutrons) - Stable, accounts for 13.17685% of natural Mercury. * 202 (122 neutrons) - Stable, accounts for 29.85714% of natural Mercury. * 203 (123 neutrons) - unstable with half life of 46.612 hours. Decays by beta- to form Thallium-203 * * 204 (124 neutrons) - Stable, accounts for 6.87% of natural Mercury. The entries with a * are synthetic isotopes of Mercury - they can only be created in a laboratory. If you work out the average Atomic Mass, weighted for elative percentage of natural abundance, then you get 199.78. Given that Mercury has 80 protons, the average number of neutrons (in a sufficiently large sample) is 119.78

∙ 14y agoThe element Mercury has 121 neutrons in it. I was looking for this answer for a science project and couldn't find it until now. I vowed to myself I would answer it on this sight so anyone else looking for it could find it!

∙ 15y agoIt depends on which isotope 202Hg, for example, contains 122

∙ 13y ago120. The atomic mass of Mercury (Hg) is about 200. The atomic number is 80.
200-80=120
Wiki User
∙ 11y agoThe atomic number of mercury is 80 and the mass number is 201. So the number of neutrons = 201 - 80 = 121.

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.
Mercury has an atomic number of 80 and a mass number of 200 How many neutrons are in one atom of mercury?
120 -have fun on studyisland(:
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.
Mercury-202 has how many neutrons in its nucleus?
Mercury has the atomic number 80 so has 80 protons. Work out the neutrons by taking the protons away from the total mass. Other isotopes of mercury are mercury-196, 197, 198, 201, 202 and 204. Each will have a different number of neutrons, giving it a different mass, bat always the same number of protons. That means always the same number of electrons too, so therefore the same chemical behaviour.
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.
How many neutrons does element mercury have?
121
How many protrons and neutrons does Mercury have?
All I know is that Mercury has 80 protons.
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.

How many neutrons and protons are in the nucleus of the element mercury?
114-124 and 80 (That's what wikipedia is good for, dummy)
How many electrons are present in an atom of mercury 201?

Does neutrons have the same amount atoms as mercury?
you would have to check out the density in order to think in neutrons so yes
