How many protons and electrons does copper ion with a charge of +2 nave.?
404624
Well, Copper always has 29 protons, otherwise it wouldn't be copper. Metallic copper has 29 electrons, because it isn't an ion. Therefore, to have that +2 charge, it must have 27 electrons (29 protons + 27 electrons = +2 charge).

The nuclear charge depends on the positively charged protons. Potassium has 19 protons and 20 neutrons. So, this makes the nucleus +19 and the mass of the atom 39 (19+20).

The atomic number is equal to the number of electrons in the atom - therefore there are 28.However, since you have a postive 3 charge, there must only be 25.\nNow normally, the number of electrons would equal the number of protons, but since you have a charge of +3, that means that there are three less electrons than protons(you don't lose protons until you get into radioactivity, and it doesn't soung like you're there yet), so that means that you have 25 electrons and 28 protons.\nThe atomic mass is defined as the number of protons + the number of neutrons, so you have 60 = 28 + (number of neutrons). Therefore, you have 32 neutrons. Good Luck!

Because the number of protons is different from the number of electrons.\n\nFor example, the uranyl ion has a total of one hundred eight protons and one hundred six electrons.

The answer is b however I don't quite follow your reasoning\n\nFaraday's constant is approximately 96500 coulomb/mole of electrons\n\nEach Ca2+ needs 2 electrons so 0.82 mole Ca2+ need 2*0.82 mole of elecrons, so a total charge of 2*0.82*F=2*0.82*96500= 1.6*10^5

2Al + 3*(CuO) -> Al2O3 + 3*Cu\n\nI2 + 2*(Na2S2O3) -> 2*(NaI) + Na2S4O6\n\nI2 + 5*(Cl2) -> 2*(ICl5)

not being a chemist, I'm not sure I know which 3, but I'm making an educated guess that the answer is protons, neutrons and electrons. If I remember correctly:\nprotons have a charge of +1 and a mass of 1\nelectrons have a charge of -1 and so very little mass that generally, they are considered to have a mass of 0.\nneutrons have no charge, and have a mass of 1

Potassium is number 19. That means it has 19 protons. If it is an atom and not an ion, it has the same nimber of electrons as protons. Since protons are positive + and electrons are negative - , they have to balance. You find the neutrons by subtracting the atomic number from the atomic mass, since both the protons and neutrons weigh 1 and make up the mass. The electrons in the energy levels can move to another atom in compound formation.(ions)

Copper's atomic mass is 63.55 grams/mole.  There are 6.02*10^23 copper atoms in mole of copper.  Thus, 1 atom Cu * 1 mol Cu/6.02*10^23 atoms Cu * 63.55 gCu/1 mol Cu = 1.056 * 10^-22 grams/atom Cu

based on the net inoic equation:\n\n\nCu2+(aq)---> Cu(s)\n\nAg+(aq)---> Ag(s) --- zero grams\n\nexcess Cu(s) or Cu(aq)\n\nif, Cu(s) then it is  3.78 grams of Ag

CuSO4+Fe = FeSO4+Cu\nCompute the number of atoms of CuSO4 in 7 gms of it, the number of atoms in 2gm of Fe. Choose the smaller number of the two. That is the number of atoms of Cu formed. Compute its weight.

Sodium has an Atomic Number of 11 and an Mass Number of 23 \n\nThis means an atom of Sodium has 11 Protons and therefore 11 electrons. \n\nSince the number of Protons + Neutrons is 23 and there are 11 Protons there must be 12 Neutrons

Here you are:\n\nCu2S + 12HNO3 => Cu(NO3)2 + CuSO4 + 10NO2 + 6H2O

electrons have negative charge

It depends on how far away from the noble gases they are. Like anything in gourp IA would be 1+, IIA 2+ etc, then when theyre closer to the right then its like VIIA 1-, VIA 2-\n\nTransition metals are different because they form multiple ions. It would indicate what the charge is.

18F\nFluorin has 9 protons(9+)and 9 electrons(9-).Therefore,there'll be no charge since positive charges from 9 protons were neutralize by negative charges of 9 electrons.+9-9=0..It is known as atom because it doesn't carry any charge.If it is ion,the amount of electron will more than proton,or the other way round.\n\nHope this will help!!=)All the best!!
