Which of the following answer choices would have the highest energy? An electron in the fourth energy level An electron in the sixth energy level An electron in the third energy level An electron in the fifth energy level

When atoms like chlorine pick up electron they release energy & assume a more stable form, the energy release is a measure of? ○ ionization energy electron affinity electro negativity nuclear energy

When John broke his arm, the doctor took an x-ray of John's arm. John had never seen an x-ray before. He asked the doctor how the x-ray was able to show his bones but not his skin and other tissue. Which explanation would the doctor best provide to John? ) X-rays have lower energy than visible light and therefore produce a black background behind the bone image. ) X-rays have higher frequency than gamma rays and therefore pass through skin and bone. ) X-rays have higher frequency than visible light and therefore can pass through skin and tissue but not through the bone. ) X-rays have lower frequency than infrared light and therefore penetrates through the bone.

What happens to an electron when an atom emits energy an electron falls to a lower energy level an electron jumps to a higher energy level   an electron collides with another electron A photon falls to a lower level of energy
