Quantum mechanics
________ explains how electrons arrange in an atom.
Hydrogen
________ acts like a nonmetal and is not included in 1A metals.
Nonmetals
________ have varied physical properties but tend to be poor conductors of heat and electricity and gain electrons in chemical reactions.
aufbau principle
The ________ says that only two electrons with opposing spins are allowed in each orbital.
Mendeleev
________ could predict elements that hadn't been discovered yet with this table.
sodium
The ________ is pumped out of cells while potassium is pumped in.
Attraction
________ decreases as particles get farther apart.
Halogens
What are reactive because they can easily gain one electron to have a noble gas configuration? Answer with a single words or term.
Sublevel energy
The spin determines how many electrons can be in one orbital. ________ splitting determines the order of orbital filling.
quantum mechanics theory
