Acopper wire is made of copper (cu) atoms. which of the following best describes the copper atoms? a. they are all exactly the same. b. they each have different numbers of protons, neutrons, and electrons. c. they are all basically the same, but the number of neutrons could vary. d. they would be mostly the same, but some would have more protons than others

Option (A) is the correct answer.

Explanation:

An element is defined as a substance that contains atoms of same type.

As copper wire is a substance that is made up of only atoms of copper. And, all these atoms of copper will be the same. Hence, it is an element.

This means that all the atoms of copper will have same number of protons, neutrons and electrons.

Thus, we can conclude that the statement they are all exactly the same best describes the copper atoms.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
