Lead will always have 82 protons. If it has a 2+ charge, that means there are 2 more protons than electrons, so there are 80 electrons.
The neutral atom has 35 electrons.
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%).
Its mass number is 80.Z=# of electrons=number of protons (unless it's an ion)A=Z+# of neutronsA=35+45=80
no of electrons in any atom is equal to the atomic number of that element so no of electron is 80
Pb lead
Hg will have 80 electrons.
Electrons each have a charge of -1. So, if the element we're trying to find is electrically neutral, it needs to have 80 protons to balance out the 80 electrons. If you look at a Periodic Table, you will see that this element is Mercury, or Hg.

70 + 80 + 70 + 30+ 80 + 80+ 80 = 490
The amount of electrons in mercury is (80)electrons.

The answer is 560. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
portons 80 neutrons 121 electrons 80
80 + 80 + 45,343 + 4,455,454 = 4,500,957
95 + 80 + 80 + 30 = 285
The result of the equation - 80 plus 90 plus 60 plus 80, is found as follows; 80 + 90 + 60 + 80 = ( 80 + 90 ) + 60 + 80 = 170 + ( 60 + 80 ) = 170 + 140 = 310 Answer = 310
