ATI Capstone Leadership 100% accurate answers. Rated A+ a nurse is planning to discharge a client who has quadriplegia to his home. the nurse suggests that the family might need respite care services. when a family member asks how respite care can help, which response should the nurse provide? respite care allows the primary caregiver time away from day-to-day care responsibilities a nurse is caring for a group of pts. which of the following clients should the nurse refer to a social wo...

Ionization Energy Ans: energy required to remove an electron from an atom in the gas phase Left Side Electrons Ans: have weaker attractions to remove electrons *easier to remove electrons from the left side of the table than the right side* Does it take MORE or LESS energy to remove an electron from Li than from Na? Ans: MORE Why? Because as we move down a group, the orbitals become larger and weaker. While going across the effective nuclear charge increases. (holds onto the electrons ...

Chem 120 exam guide highly recommended Degenerate Degenerate orbitals = 2+ orbitals w/equal energy (ex= 2p) -One electron goes into each degenerate orbital before any pairing occurs Requires energy 1s-> 2s requires energy -energy levels are dictated by principle quantum number (n) -need more energy for an electron to move away from the nucleus -energy levels get closer together as they increase in quantum number Orbitals B/c 2s and 2p orbitals have the same principal quant...
