Chemistry electron configuration test study guide – Flashcards

an electron discoverer

The total amount of energy level an atom has. (7)

Fourth quantum number. Designated as ms. It specifies an electron's intrinsic spin or angular momentum value in an orbital. There can be no more than two electrons per orbital, the value of ms can only be +1/2 or -1/2. According to Hund's Rule, the electrons are likely to be in parallel spin, hence there's no 0.

it is impossible to know exactly both the velocity and the position of a particle at the same time

Symbolized by m, indicates the orientation of an orbital around the nucleus.

the quantum mechanical solution to a wave equation that designates the sublevel, or set of orbitals, within a given major energy level in which an electron resides

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

three dimensional regioin around the nucleus that indicates the probable location of an electron

Within each principle energy level, there are several different energy levels with different shape

Arrangement of electrons in the orbitals of an atom.

model of an atom that shows electrons in circular orbits around the nucleus

a electron configuration in which electrons are represented as arrows in boxes corresponding to orbitals of a particular atom.

An abbreviated electron configuration of an element in which filled inner shells are represented by the symbol of the preceding noble gas in brackets

A model of an atom in which each dot represents a valence electron

A pure substance that cannot be broken down into other substances by chemical or physical means
