Atomic Structure, Isotopes, and Ions

Atoms of the same element with different numbers of neutrons are called

• Ions
• Isotopes
• Iotas
• Introns

What has to be done to an object to give it a negative charge?

• Add negative electrons

• Remove positive charges

• Remove negative charges

• Add positive charges

If we want to make an element have a positive ion charge, why don't we just add one proton?

• Changing the number of protons would change the element.

• Protons are permanently attached to the neutrons.

• Protons are protected inside the nucleus, making it impossible to move.

• It's easier to add electrons.

In an atom of boron-11, has a mass number of 11 how many neutrons are present?
