how many electrons are in the world?
448772
The answer is 1.75 x 10^51. The answer is 1.75 x 10^51. The simplest way to determine this is to calculate the number of protons in the earth. The number of electrons will be equivalent to the number of protons.

Thus, in the average human body, there will be 50000 g/ 12 g = 4167 packets of 12 g of carbon each, i.e. 25002 x 10^23 atoms, or, expressed more conventionally, 2.5 x 10^27 atoms. Each of these has six electrons. I.e. the average human body contains about 1.5 x 10^28 electrons.

That's what a mole is and 6.022 x 10^23 is the Avogadro number. So, 1 mole of electrons is 6.022 x 10^23 electrons.

There are 18 electrons in 3rd shell of the copper atom.
1421824
Argon's atomic number is 18 and there are 18 electrons in each atom. Under appropriate physical conditions one can make all the 18 electrons unpaired or 16, 14, 12, 10, 8, 6, 4, 2 electrons unpaired.

Nano coulomb means 10-9 power. The number of electrons is 6.24 * 1018. That is the number of particles in one coulomb.
210258
So... for the element of ALUMINUM, you already know that the atomic number tells you the number of electrons. That means there are 13 electrons in a aluminum atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and three in shell three.

The fourth energy level has 18 electrons. The fourth energy level of the periodic table includes the 4s 3d and 4p orbitals. The 4p orbital holds 6 electrons. There is a 4d orbital with 10 electrons which coincides with the 5th energy level of the periodic table.
707402
The L shell only holds eight electrons. The M shell only holds eight electrons. The M shell can actually hold up to 18 electrons as you move to higher atomic numbers. The maximum number of electrons you will find in any shell is 32.

one electron has a charge of 1.6×10⁻¹⁹ joules.As u r telling one joule it has energy of 1 joule it has 1÷(1.6×10⁻¹⁹) electrons.
519976
The fourth and higher levels also have an f sublevel, containing seven f orbitals, which can hold a maximum of 14 electrons. Thus, the fourth level can hold up to 32 electrons: 2 in the s orbital, 6 in the three p orbitals, 10 in the five d orbitals, and 14 in the seven f orbitals.
