121 neutrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
200because the pizza guy came to my houseand i asked him the same question and he told me 200....or maybe that was the bill??
The amount of electrons in mercury is (80)electrons.
In one mole of H2, there are six electrons present. Two electrons are contributed by each hydrogen atom.
There are 3 pairs of valence electrons present on the boron atom in BF3. Boron has 3 valence electrons, and each fluorine atom provides one additional electron, giving a total of 6 valence electrons on boron.
There are no unpaired electrons in an unexcited neutral mercury atom; its outer shell contains only two s electrons that are paired, as are all the electrons in the filled inner shells of the atom.
A Mercury atom has 80 electrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
no of electrons in any atom is equal to the atomic number of that element so no of electron is 80
Mercury is a non metal element. There are 80 electrons in a single atom.
no of electrons in any atom is equal to the atomic number of that element so no of electron is 80

Mercury has 80 electrons which means there are 6 shells in a neutral atom of mercury.
There are 5 valence electrons present in the atom Nb (niobium), as it is located in group 5 of the periodic table.
That depends on the element you are considering. For a neutral atom, the number of electrons = number of protons = atomic number
The amount of electrons in mercury is (80)electrons.
There are no electrons present in a helium atom in its second energy level.
