Chemistry A Molecular Approach AP Edition Chapter 8

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

The ________ describes the behavior of elements.

Metallic character

What is important because there are many metals on the periodic table? Answer with a single words or term.

Alkali metals

________ can easily lose an electron to have noble gas configurations.

Noble gases

________ can be used to represent inner electrons.

Penetrations

What is when an electron gets closer to the nucleus? Answer with a single words or term.

Transition elements

________ make up the d orbitals.

Fluorine

What is the most powerful oxidizing agent? Answer with a single words or term.

atomic radius

What is largely determined by the number of valence electrons? Answer with a single words or term.

Helium

________ has 2 valence electrons.

Electron configurations

________ shows the particular orbital that electrons occupy.

Anions

________ are much larger than their normal atoms.

Orbitals

________ fill from left to right.

Valence electrons

What are important for chemical bonding? Answer with a single words or term.

orbital diagram

A(n) ________ symbolizes the electrons as an arrow and the orbital as a box.

Ionization energy lowers

________ going down a column.

Periodic properties

________ are predictable based on the element's position on the table.
