Charges for protons neutrons and electrons for copper?
Protons have a positive charge of +1 elementary charge, electrons have a negative charge of -1 elementary charge, and neutrons are neutral with no charge. Copper has 29 protons and 29 electrons, so it is overall electrically neutral.
A 2-mm-diameter copper ball is charged to plus 50 nC What fraction of its electrons have been removed?
To find the fraction of electrons removed, we need to calculate the total charge of the copper ball when neutral, then compare it to the charge when +50 nC. Each electron has a charge of -1.6 x 10^-19 C. The number of electrons removed can be found by dividing the difference in charge by the charge of an electron. This will give us the fraction of electrons removed.
What is the number of electrons for copper positive 1 ion?
The number of electrons for copper positive 1 ion is 28.
What is the net charge of a copper atom if it gains two electrons?
Copper loss electrons.
Is copper positively charged or negatively charged?
A copper ions has a positive charge, most commonly 2+.

Why do zinc and copper work well together to generate energy?
Zinc and copper work well together in a galvanic cell because zinc readily loses electrons while copper readily gains electrons. This difference in reactivity leads to the flow of electrons from the zinc electrode to the copper electrode, creating an electrical current that can be harnessed as energy.
What is the number of electrons for copper positive 1 ion?
The number of electrons for copper positive 1 ion is 28.
What is the net charge of a copper atom if it gains two electrons?
Copper loss electrons.
Is copper positively charged or negatively charged?
A copper ions has a positive charge, most commonly 2+.
What is the charge of copper if it gains three electrons?
Assuming the copper started at ground state, after gaining 3 electrons, it would have a charge of -3.
The removal of an electron results to what charge?
+1. Because an atom normally has an equal number of protons and electrons, it is neutral. By removing a negative (the electron), the atom is then positive. The more electrons you remove, the more positive the atom becomes. Then, it is called an ion, such as Cu is copper, but Cu2+ is a copper(II) ion; it is a copper atom that has lost two electrons.
What is the predominant carrier of electrical charge in a copper wire?
The predominant carrier of electrical charge in a copper wire is the free electrons within the copper atoms. These free electrons are able to move easily through the lattice structure of the copper, allowing for the flow of electric current.
How can you charge copper rod by holding it and rubbing it?
By rubbing the copper rod with a cloth or your hands, you transfer electrons between the rod and the fabric through friction. This process creates a build-up of static charge on the surface of the rod, giving it a net positive or negative charge.
How many electrons does an atom of copper have?
Copper is a metal element. There are 27 electrons in a single atom.
How many protons are in a copper ion with a positive 2 charge?
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.
