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.

Ag+ = 47 electrons - 1 electron = 46 electrons. Finally: 47 protons , 61 neutrons and 46 electrons.

A neutral atom with atomic number 20 will have 20 electrons. The atomic number is, by definiton, the number of protons in an atom's nucleus but for a neutral atom it's also equal to the number of electrons. Each element has a different, unique number of protons that determines its identity.

So... for the element of CHLORINE, you already know that the atomic number tells you the number of electrons. That means there are 17 electrons in a chlorine atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and seven in shell three.

Depending on the atomic mass, you can calculate the number of atoms, and by knowing the number of electrons in the various orbits of each atom, you can find out the total number of electrons. If you were asking for 1 kg of electrons and it's count, then 'n'= 10/(9.11*10^-31)= approximately 10^31 electrons.

So... for the element of BORON, you already know that the atomic number tells you the number of electrons. That means there are 5 electrons in an boron atom. Looking at the picture, you can see there are two electrons in shell one and three more in shell two.

8 elements in the second row, 8 electrons in the second orbit. 8 elements in the third row, 8 electrons in the third orbit. The fourth and fifth orbits would therefore hold 18 electrons.

Each principal energy level can contain up to 2n2 electrons, where n is the number of the level. Thus, the first level can contain up to 2 electrons, 2(12) = 2; the second up to 8 electrons, 2(22) = 8; the third up to 18, 2(32) = 18; and so on.

So... for the element of SULFUR, you already know that the atomic number tells you the number of electrons. That means there are 16 electrons in a sulfur atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and six in shell three.
110055
There are 6.25*10^18 electrons in 1 coulomb of charge. We know that the a electron have charge of 1.6 × 10−19 C. then 6.65 * 1018 electrons constitute a coulomb of charge.
