an area where an electron may be found 90% of the time

a description of the atom in its ground state

$$3.0x10^8\ \frac{m}{s}$$ is

the number of complete wave cycles per second

$$6.62x10^{-34}\ J\ s$$ is

total valence electrons in the whole periodic table

Writing the noble gas of the previous principal energy level and then the sublevels that follow is known as

abbreviated electron configuration

Astronomers use emission spectra to evaluate the different elements contained within stars. Why?

Each element has a unique "fingerprint" based on their electrons' excited and ground states.

Astronomers aren't real scientists.

Stars can only be seen with the human eye.

Some species of bacteria produce bioluminescence, so stars do also.

Which radiation travels the fastest?

they all travel at the same speed

Why might the bottom of your pots and pans at home "glow" when heated over the stovetop?

The electrons in the metal are excited and then emit light when falling back to ground state.

They are not built to withstand the heat

The electrons are in their ground state and emit light in order to get excited.

Aufbau Principle states that

electrons occupy lowest available energy levels first

the electrons must ride the bus

only two electrons spinning in opposite directions are allowed in an orbital

each orbital of equal energy must have one electron before a second electron is added

Pauli Exclusion Principle states that

only two electrons spinning in opposite directions are allowed in an orbital

the electrons must ride the bus

electrons occupy lowest available energy levels first

each orbital of equal energy must have one electron before a second electron is added

Hund's Rule states that

each orbital of equal energy must have one electron before a second electron is added

the electrons must ride the bus

electrons occupy lowest available energy levels first

only two electrons spinning in opposite directions are allowed in an orbital
