Why do electrons enter the 4s orbital before entering the 3d orbital?

because the 3d orbital is at a lower energy level

because both the 4s and 3d orbitals are at the same energy level

because the 4s orbital is at a lower energy level

because the 4s orbital is at a higher energy level

How many moles of oxygen gas are produced from the decomposition of six moles of potassium

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
