Which statement best explains why radon and krypton do not bond easily with other elements? O. They have many electron shells, so their protons do not attract electrons strongly.
O They have eight electrons in their valence shells, so they are stable without gaining or losing electrons.
O Their valence shells are empty, so they do not need to bond with other elements to be more stable.
O Their valence shells are so close to the protons in the nucleus that bonding cannot happen like in other elements.​

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
