1.602 x 10-19 C is the charge because of one electron
So 12 C will be due to 12 / 1.602 x 10-19 = 7.49 x 10 19 electrons.
539000 times as much as 1 coulomb.
To find the number of electrons in a charge, you divide the charge by the charge of a single election. In this case it would be: -1C/(-1.6x1o^-19)=6.25x10^18 So 6.25x10^18 electrons are necessary to produce a charge of 1 C
It should gain 2 electrons
Electrons have a negative charge, and protons have a positive charge. If i have more protons(plus charges) than electrons(minus charges) overall the atom will have a positive charge(mabye +1 or +2 etc....depending how many more protons there are compared to electrons) If there are more electrons(minus charges) than protons(plus charges) then overall the atom will have a negative charge(mabye -1 or -2 etc....depending how many more electrons there are compared to protons) These charged atoms are known as ions.
18. Phosphorus posses 15 electrons and 15 protons, respectively its charge is 0.By accepting 3 more electrons, with their negative charge the total charge of the atom would decrease by 3.So the total charge would be -3 and the total number of electrons would be 18.
In one Coulomb of negative charge, there are approximately 6.24 x 10^18 electrons. This is because each electron has a charge of -1.6 x 10^-19 Coulombs, and one Coulomb is equivalent to 6.24 x 10^18 electrons.
6.242 x 1018
It takes 6.25E18 electrons to produce 1 coulomb of charge.
There are about 6.24 x 1018 electrons (or protons) in one coulomb of charge.
One coulomb is equivalent to approximately 6.242 x 10^18 electrons.
The elementary charge ... the amount on one electron or one proton ... is 1.602 x 10-19 coulomb.So, in order to collect one coulomb, you'd need 6.242 x 1018 electrons or protons.(That's the number of electrons that pass by the middle of the wire every secondwhen the current in it is 1 Ampere.)
Charge on electron = - 1.602 X 10 -19 coulomb, so..., - 58. 0 coulomb/- 1.602 X 10 -19 coulomb = 3.62 X 1020 electrons ===============
When an object has too many electrons, it carries a negative charge. This is because electrons have a negative charge, so an excess of electrons on an object results in an overall negative charge.
One electron has - 1.602 X 10 -19 coulomb of charge. So disregarding the negative sign....., 2.86 C/1.602 X 10 -19 C = 1.79 X 1019 electrons in that much charge. ============================
3.2 millicoulomb (1 coulomb/1000 millicoulomb)= 0.0032 coulomb--------------------------Charge on one electron sans negative sign...,1.602 X 10 -19 coulomb---------------------------so,0.0032 coulomb/1.602 X 10 -19 coulomb= 2.0 X 1016 electrons================
There are 6.24×10^18 electrons in 1 coulomb. Therefore, in 1 million coulombs of charge, there would be 6.24×10^18 multiplied by 1 million electrons, which equals 6.24×10^24 electrons.
20 coulomb (1 coulomb/1.602 X 10 -19 coulomb ( electron charge ) = 1.2 X 1020 electrons needed =======================
