Why do most metals exist in nature as minerals rather than as pure metallic elements?

Because most metals are susceptible to oxidation, having low electronegativities, prefering to be in a cationic form vs. ... Only metals such as gold, which is resistant to oxidation, will be found pure in nature.

Forgot the question hahaha

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
