Understanding Ions and Their Charges

What is an ion?

• A molecule with a charge

• A compound with a charge

• An atom with a charge

• An atom with a neutral charge

How do you determine the charge of an ion?

• By adding the number of electrons and neutrons

• By adding the number of protons and neutrons

• By subtracting the number of neutrons from protons

• By comparing the number of protons and electrons

What happens to the electrons when an ion has a positive charge?

• Electrons are added

• Neutrons are removed

• Electrons are removed

• Protons are added

In the example of zinc with a +2 charge, how many electrons does it have?

• 28 electrons

• 32 electrons

• 30 electrons

• 34 electrons

For bromine with a -1 charge, how many electrons are present?

• 35 electrons

• 34 electrons

• 36 electrons

• 37 electrons
