What is the number of neutrons and electrons of mercury?
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
How many neutrons does Mercury have in it?
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
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 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 electrons are present in an atom of mercury 201?
121 neutrons.
What element has a mass number of 122 and 72 neutrons?
Mercury (Hg) has an average atomic mass of 200.59. This is an average based on the percentages of the naturally occurring isotopes of Mercury. There is an isotope of Mercury that has 201 particles in the nucleus. Since Mercury's atomic number is 80, Mercury-201 has 80 protons and 121 neutrons in its nucleus.
What is the mass number of Hg?
Mercury is a metal element. Atomic number of it is 80.

What is element mercury mass number?
Perhaps you should google "Mercury's atomic mass" I'm sure there are thousands of sites out there that could help you out. Or, if you're feeling adventurous, maybe you could look at a periodic table.
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 mercury s atomic number?
Mercury is a metal element. Atomic number of it is 80.
What will be the no of neutrons protons of hg having mass no 200 atomic no 80?
The number of protons = the atomic number. The number of neutrons = the mass number - the atomic number Protons = 80 Neutrons = 120 Also, for extra information, not that you need it, the element would be mercury.
How many electrons are present in an atom of mercury 201?
121 neutrons.
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.
