To accurately complete the sentences, I would need specific information about the elements X, Y, Q, and R. Without that context, I can't determine the correct answers. However, based on the options provided:
- If Elements X and Y are not the same, then they are "different elements."
- If Elements Q and R have different atomic forms or have a different number of neutrons, they could be described as "isotopes" if they are the same element.
- If they have gained or lost electrons, they could be "ions."
Please provide the specific characteristics or context of elements X, Y, Q, and R so I can assist you accurately!
