The number of electrons is the same as the number of protons or the atomic number. If the element is an ion of e.g O+2, you would take away 2 from the atomic number and if it is O-2, you would add two electrons
First you would calculate the number of protons...
the number of protons = the total mass number
then the number of protons should = the nummber of electrons(unless their is a number in front of the element like +1)
therefore= # of protons = # of electrons
what is the formula for finding electrons in a normal atom
It is the same as the atomic number of the element.
For a neutral atom, the atomic number is same as the number of electrons or number of protons.
8 means the number of electrons on the second valence layer.
Well the formula for calculating the maximum amount of electrons that can be held in a shell of an atom is: 2(n)2 N being the shell number. For example: 2(1)2= 2 (the maximum amount of electrons for shell number 1)
FeN , because the +3 electrons from the Iron (Fe) ion and the - 3 electrons from the Nitride (N) cancel each other out making it FeN
Electricity is not a chemical and it does not have a chemical formula. Electric current consists of moving electrons; static electricity consists of unmoving electrons.
6th energy level can hold 72 electrons. (has s,p,d,f,g, and h subshells)
by counting them
number of electrons
number of electrons
The number of electrons needed to lose or gain is its Valency
Zinc chloride has the chemical formula ZnCl2.The total number of protons is 64; the total number of electrons is also 64.The number of neutrons depends on the isotopes of Zn and Cl.
The maximum number is 8 electrons in the second shell.
The maximum number of electrons in a shell / energy level is given by 2n2.
Electron dot formula tells the number of valence electrons
Use the formula 2n2. In this case n = 3, so 2(32) = 18. The sublevels and number of electrons in each are 3s23p63d10, for a total of 18 electrons.
The formula to determine the number of electrons in an energy level is 2n2, where n is the number of the energy level. For the fifth energy level, n=5. So the total number of electrons possible in the fifth energy level is 2(52) = 50.
8 means the number of electrons on the second valence layer.
When n=2, you have an s orbital with 2 electrons, and you have 3 p orbitals each with 2 electrons (total of 6). So, total number of electrons for n=2 is 8 electrons.
