Study Notes

Transition Metals

Transition metals are located in Groups 3 through 11 of the periodic table.

Metals

Metals are shiny elements known for their excellent conductivity of heat and electricity.

Metalloids

Metalloids possess characteristics of both metals and nonmetals.

Alkali Metals

Group 1 elements are referred to as alkali metals.

Alkaline Earth Metals

Group 2 elements are known as alkaline earth metals.

Halogens

Group 17 elements are classified as halogens.

Noble Gases

Group 18 consists of noble gases, which are non-reactive.

Nonmetals

Nonmetals do not conduct electricity, are dull in appearance, and are brittle.

Malleability

Malleable materials can be easily shaped or hammered into thin sheets.

Chemical Properties of Metals

Metals typically form positive charges by losing electrons.

Chemical Properties of Nonmetals

Nonmetals tend to form negative charges by gaining electrons.

Electronegativity

Electronegativity measures an atom's attraction for electrons.

Radioactivity

All elements with an atomic number above 83 are radioactive.

Most Reactive Metal

Francium (Fr) is recognized as the most reactive metal.

Most Reactive Nonmetal

Fluorine (F) is the most reactive nonmetal.

Nonreactive Group

Group 18 elements are considered nonreactive due to their stable electron configuration.

Hydrogen Classification

Hydrogen is categorized as a non-metal.

Commonality in Group Elements

Elements in the same group have the same number of valence electrons.

Commonality in Period Elements

Elements in the same period share the same number of electron shells.

Measure of Attraction for Electrons

Electronegativity quantifies an atom’s ability to attract electrons.

Ionization Energy

Ionization energy refers to the energy needed to remove an electron from an atom.

Atomic Radius

Atomic radius measures the size of an atom from its nucleus to its outermost electron.

Atomic Radius Trends

Atomic radius increases down a group and decreases across a period from left to right.

Example of a Metalloid

Antimony (Sb) is identified as a metalloid.

Example of a Solid Metal

Tin (Sn) is classified as a solid metal.

Example of a Liquid Metal

Mercury (Hg) is notable for being a liquid metal.

Ductility

Ductility refers to the ability of a material to be stretched into a wire.
