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.​

An astronaut floating in space is trying to use her jetpack to get back to her space station, but she is being pulled away by a nearby planet, as shown in the image below. her jetpack provides a constant thrust of 310 n. if she angles her jetpack in such a way that it cancels out the vertical force due to the planet's gravity, what is her net horizontal force? thaud 487 o a. 54.8 n toward the space station o b. 212.9 n toward the space station o c. 185.2 n toward the space station o d 956 n toward the space station
