e- tend to occupy lower energy levels first

Aufbau Principle

Pauli´s exclusion Principle

No e- in a single atom is going to have the set of Q.N. as other e- in the same atom

Heisenberg´s uncertainty Principle

It is impossible to know with great precision both the momentum and position of an e-

Hund´s rule

When doing an orbital diagram, write unpaired e- first e- in a single orbital will have opposite spin (up, down)

A (Los primeros 2 y los últimos 6)

Groups: Representatives

B (Desde el 3 al 12)

Groups: Transition

Group 1:Alkali metals

-Metals, -Soft -Very reactive

Group 2:Alkaliearthmetals

-Metals -Soft -Reactive Less than Group 1

Inner-Trans Metals

-57-71 Lanthanides -89-103 Actinides -------Radioactive -93-103 Synthetic

Group 3-12: Transition Metals

-Solid except Mercury Hg -Excellent conductor of heat and electricity -Malleable and ductile

Group 13,31,49,50,81,82,83,84: Post-transition metals

-Good conductors of heat and electricity -Malleable and ductile -Softer -Higher densities

Group 5,14,32,33,51,52,84,85: Metalloids

-Somewhat malleable -Conductors ONLY under the right conditions

Group 1,2,6,7,8,9,10,15,16,17,18,34,35,36,53,54,85,86: Non-metals

-Brittle -Not conductors -Isolator

Group 17: Halogens

-Most Electronegativity (the intensity with which an Atom attracts electron)

Group 18: Nobel gases

-Least reactive


Protons From left to right it increases From top to bottom it increases

Atomic radius

Measurement of the size From top to bottom it increasesFrom left to right it decreases

Metallic character

Physical and chemical characteristics of metals All the metals are towards the left


Affinity that an atom is going to have towards electrons From left to right it increases From bottom to top it increases

Ionization energy

The energy necessary to take away an electron from an atom From left to right it increases From bottom to top it increases

Electron Affinity

The energy necessary to give an electron to an atom From left to right it increasesFrom bottom to top it increases

Valence e-

Son los electrones que los atomos van a usar para interactuar con otros atomos y crear enlaces

Octet rule

Todos los atomos buscan tener 8 electrones de valencia y por ende tener configuracion de gases noles porque son los mas estables

Lewis structure

La forma de representar un elemento con sus electrones de valencia, solo elementos representativos

Lewis structure, K

Lewis structure, In

Ionic Bond

Transferencia de electrones, metal- no metal

Ionic bond *

-E.N> 1.7


E.N. FeBr2


The chemical bond between two Nonmetals and the electrons are shared
