The atomic number of copper is 29. Thus, neutral copper would have 29 protons and 29 electrons. However, since we're dealing with Cu2+, we need to subtract 2 electrons from that number, leaving us with 27.

∙ 13y agoCopper's, or Cu's, atomic number is 29. This number tells us that copper has 29 protons. The two stable isotopes of copper are 63Cu and 65Cu, which have 34 and 36 neutrons per atom, respectively. The 2+ that you mentioned in your question only concerns electrons, so what I wrote above applies for Cu2+ as well.

∙ 11y agoCopper -always- has 29 protons. If it didn't have 29 protons it wouldn't be copper, it would be another element. The charge of an atom has to do with the electrons associated with that atom. Neutral copper has 29 electrons associated with it (the positive 29 charge from the 29 protons is balanced by the negative 29 charge of the 29 electrons). If a copper atom has a plus two charge that means that two of the coppers electrons have been stripped from it (how this happens is the answer to another question!). The remaining 27 electrons can balance the charge of only 27 of the protons, so overall, the copper atom (still always the copper atom) has a charge of plus two.

∙ 16y agoThere would be a total of 27 electrons because the total number of protons are 29 so to make the ion more positive the would have to be less electrons than protons.

∙ 13y agoNormally Cui has 29, however a positively charged Cu would have one less than 29 i.e. 28. A Cu2+ would have 27.

∙ 14y agoUse this simple formula, Ion Charge=#protons - #electrons
Cu+2 2+=29p-27e
So it has 29protons and 27electrons be cause the Ion Charge is plus 2.

An atom contains fewer electrons than protons has as negative ionic charge?
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.
If an atom of an element has six protons and eight neutrons how many electrons is in this atom if its neutral?
When we consider charged particles, we are only concerned with protons and electrons. Neutrons have no charge, so they don't contribute to a positive or negative charge. Protons have a positive charge and electrons have a negative charge. They are both equally positive and negative, that is to say one proton cancels out the charge of one electron. So as long as there are equal numbers of protons and electrons, the particle will be neutral. If there are six protons, then there needs to be six electrons in order to be neutral.
Why are there as many electrons as protons in a atom?
Because Electrons have a negative charge (e-) and Protons have a positive charge (p+), so to create a balanced atom you must have the same number of e- as p+
How many protons does the isotopes from copper have?
26 protons
The charge of an atom's nucleus is what?
The charge of an atom's nucleus is always positive.
How many protons do silicon have?
The number of protons in silicon is 14. The amount of protons in an element can impact its positive charge.
How many electrons do protons have?
There are the same number of protons as electrons in each atom unless the atom does not have a neutral charge, if it has a negative charge it has that more electrons, and if it has a positive charge it has that much more protons hope this helps

How many electrical charges are in protons?
A proton has single positive charge neutrons have no charge and a electron has a single negative charge
How many electons are in a neutral atom?
A neutral atom has as many electrons as protons. This is because protons have a positive charge and electrons have a negative charge, but because there are the same number of them, they cancel each other out.
How many protons does an atom of copper?
An atom of copper has 29 protons.
What is the charge of an ion that contains 16 protons?
i think it depends how many electrons it has. then you do something like subtract the electrons from the protons. electrons are negative, protons are positive.

What an electrical charge?
AnswerElectric charge (or electrical charge) is nothing but property possessed by various particles including the protons and electrons in atoms. Protons always have a positive charge and electrons a negative charge. There are also other particles such as positrons which have a positive charge and anti-protons which have a negative charge. Many of these (protons and anti-protons) are also made up of quarks which have a charge of 1/3. An accumulation of particles with the same charge generates a larger and larger electrostatic field the more and more that accumulate. The magnitude of charge for a proton is +1.602 x 10 -19 Coulombs while that of an electron is -1.602 x 10 -19
