To find the total number of electrons in an element, first you need to look up the element's atomic number. That number tells you how many protons are in the element. Then, look up the net charge of the element. The number of protons subtracted by the elements net charge will give you the number of its electrons.
Who told you that chromium had 118 electrons - there are only 24. Check it out with Wikipedia. There you find the element that really has 118 electrons. Happy hunting. (PS - Hint - there is a very close correlation between the number of electrons and the atomic number of the element.)
In a neutral atom the number of electrons is the same as the atomic number, which is the number of protons in the nucleus.
To find out the number of electrons in an element you must add the protons and neutrons and subtract that number with the atomic mass, this will determine the amount of electrons because the unknown element could be an isotope and have more than the normal amount of electrons of the non isotope element.
Molybdenum is the element that has 42 electrons.
Hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium have one valence electron.
Argon is a noble gas belonging to group 18. It has 8 valence electrons.
To find the total number of electrons in an element, first you need to look up the element's atomic number. That number tells you how many protons are in the element. Then, look up the net charge of the element. The number of protons subtracted by the elements net charge will give you the number of its electrons.
The atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.
Finding the electron of an element is easy. In if find through atoms which positively charged protons and the negatively charged 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.
Aluminium is a metal element. There are 13 electrons in a single atom.
The Element Neon has 10 protons and 10 electrons.
In a neutral atom the number of electrons is the same as the atomic number, which is the number of protons in the nucleus.
Mass number..can be calculated..by the sum of No. of protons and the No. of electrons. And this would give you the the mass number of the element.
