What is the number of neutrons and electrons of mercury?

Answer 1

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

Answer 2

The 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*

Answer 3

The 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.

Answer 4

From 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.

Answer 5

Protons-*)

Neutrons-!@!

Elecrtons-*)

Me? 21

You?ZERO

Answer 6

100% alone and natural would be 80 electrons but both neutrons and electrons change.

Answer 7

Mercury has 80 protons and electrons and a variable number of neutrons, depending on the isotope.

Answer 8

Mercury has 80 electrons because it has an atomic number of 80. The most common isotope of mercury, mercury-202, has 120 neutrons.
