A chlorine ion contains 17 protons, 16 neutrons, and 18 electrons. What is the net charge of the ion in Coulomb?

net charge or -1

To determine the net charge of an ion, we need to compare the number of protons (which have a positive charge) to the number of electrons (which have a negative charge).

In this case, a chlorine ion has 17 protons and 18 electrons.

Since electrons have a negative charge, we subtract the number of electrons from the number of protons to calculate the net charge.

Net charge = number of protons - number of electrons
Net charge = 17 - 18
Net charge = -1

Therefore, the net charge of the chlorine ion is -1 Coulomb.

To determine the net charge of an ion, we need to compare the number of protons (positive charge) to the number of electrons (negative charge).

In the case of a chlorine ion, we know that the atomic number of chlorine (Cl) is 17, which means it has 17 protons. The number of neutrons is not relevant for determining the net charge.

The given question states that the chlorine ion has 18 electrons. Since electrons have a negative charge, we can deduct that the chlorine ion has one extra electron compared to its 17 protons.

Now, to convert this extra electron into Coulombs, we need to remember the elementary charge. One elementary charge is approximately equal to 1.6 x 10^(-19) Coulombs.

Since the chlorine ion has one extra electron, the net charge of the ion is equal to the elementary charge, which is approximately 1.6 x 10^(-19) Coulombs.
