Chapter 5_6 chem vocab.txt

A mathematucal expression describing the probabilty of finding an electron at various locations

The rule that electrons occupy the orbitals of lowest energy first

The arrangement of the elctrons of an atom in its ground state into various orbitals around the nucle of atoms

The apecific engeries an electorn in an atom or other system can have

Electrons occupy orbitals of the same energy in a way that makes the number or electrons with the same spin direction as large as possible

An atomic orbital may describe at most two electron, each with opposite spin direction

The amount of energy needed to move an electron from one energy level to another

The modorn description, primarily mathematical, of behavior of electrons in atoms

Any metals in group 1A of the perodic table

And metal in group 2A of the perodic table

Any atom or group of atoms with a negative charge

One half the distance between the nuclei of two atoms of the same element when the atoms are joined

Any atom or group of atoms with a posotive charge

The ability of an atom to attract electrons when the atom is in a compound

A nonmetal in group 7A of the periodic table

An element in the lantharide pr actiride series; the highest occupies "s" sublevel and nearby "f" sublevel of its atoms generally contain electrons

An atom or group of atoms that has a positive or negative charge

The energy required to remove an electron from an atom in its gaseous state

An element that tends to have the propeeites that are similar to those of metals and nonmetals

One of a class of elements that are good conducts of heat and electric current. Metals tend to be ductile, malleable and shiny

An element of group 8A of the perodic table. Stable elements

An element that tends to be a poor conductor of heat and electric current; opposite of metals for the most part

When the elements are arranged in increasing atomic number. A repetition of their physical and chemical properites

An element of group "A" in the perodic table

One of the group "B" elements in which the highest occupied "s" sublevels and nearby "d" sublevel generally contain electrons
