The main reason for the observed trend is that Explain your reasoning. additional oxygen atoms draw electron density away from more electrons in the valence shell add electron density to more electronegative elements weaken atoms with a larger atomic radius weaken

Determine the wavelength of the light absorbed when an electron in a hydrogen atom makes a transition from an orbital in the n=3 level to an orbital in the n=7 level.

Can you me with this i really appreciate it

The twister and runaway train are two coasters at the same amusement park. both coasters start at the same height. the coaster for the twister is twice the mass of the coaster for the runaway train. which roller coaster has greater gravitational potential energy at the start of the ride?
