Electromagnetic radiation (^) is energy that travels as waves through space (^) is described in terms of wavelength and frequency (^) moves at the speed of light in a vacuum speed of light = 3.0 x 10 8 m/s
An atomic spectrum consists of (^) lines of different colors formed when light from a heated element passes through a prism (^) photons emitted when electrons drop to lower energy levels
(^) An electron absorbs energy to “jump” to a higher energy level. (^) When an electron falls to a lower energy level, energy is emitted. (^) In the visible range, the emitted energy appears as a color.
In each of the following energy level changes, indicate if energy is
Sublevels (^) contain electrons with the same energy (^) are found within each energy level. (^) are designated by the letters s, p, d, and f The number of sublevels is equal to the value of the principal quantum number (n ).
An orbital (^) is a three-dimensional space around a nucleus where an electron is most likely to be found (^) has a shape that represents electron density ( not a path the electron follows) (^) can hold up to 2 electrons (^) contains two electrons that must spin in opposite
An s orbital (^) has a spherical shape around the nucleus (^) increases in size around the nucleus as the energy level n value increases (^) is a single orbital found in each s sublevel
Each sublevel consists of a specific number of orbitals_._ (^) An s sublevel contains one s orbital. (^) A p sublevel contains three p orbitals. (^) A d sublevel contains five d orbitals. (^) An f sublevel contains seven f orbitals.
