GRUPOS Y FAMILIAS DE LA TABLA PERIÓDICA

Introduction to Groups and Families in the Periodic Table

In this section, we learn about the groups and families in the periodic table, their characteristics, and how they are organized.

Groups and Families in the Periodic Table

• The periodic table is divided into columns called groups or families, which represent elements with similar properties.

• Elements within a group or family have the same number of valence electrons and exhibit similar chemical properties.

• The elements in Group A are known as representative elements or main-group elements, while those in Group B include transition metals and inner transition metals (lanthanides and actinides).

Group 1A - Alkali Metals

This section focuses on Group 1A, also known as alkali metals.

Alkali Metals (Group 1A)

• Alkali metals include hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium.

• They have a +1 oxidation state.

• Alkali metals are highly reactive due to their low ionization energy.

Group 2A - Alkaline Earth Metals

This section discusses Group 2A, also known as alkaline earth metals.

Alkaline Earth Metals (Group 2A)

• Alkaline earth metals include beryllium, magnesium, calcium, strontium, barium, and radium.

• They have a +2 oxidation state.

• These elements are less reactive than alkali metals but still more reactive than most other elements.

Group 3A - Boron Family

This section explores Group 3A, also known as the boron family.

Boron Family (Group 3A)

• The boron family includes boron, aluminum, gallium, indium, and thallium.

• Elements in this group have a +3 oxidation state.

• They exhibit both metallic and non-metallic properties.

Group 7A - Halogens

This section focuses on Group 7A, also known as halogens.

Halogens (Group 7A)

• Halogens include fluorine, chlorine, bromine, iodine, astatine.

• They have a -1 oxidation state.

• Halogens are highly reactive non-metals.

Group 8A - Noble Gases

This section discusses Group 8A, also known as noble gases.

Noble Gases (Group 8A)

• Noble gases include helium, neon, argon, krypton xenon radon oganesson.

• They have a 0 oxidation state.

• Noble gases are characterized by their low reactivity and stable electron configurations.

Lanthanides and Actinides

In this section, we learn about the lanthanides and actinides series of elements.

Lanthanides and Actinides

• Lanthanides are elements with atomic numbers from 57 to 71. They include lanthanum to lutetium.

• Actinides are elements with atomic numbers from 89 to 103. They include actinium to lawrencium.

• Lanthanides and actinides are transition metals with similar properties but differ in their electron configurations.

Periods and Rare Earth Elements

This section explains periods and rare earth elements.

Periods and Rare Earth Elements

• Periods are the rows in the periodic table, representing the number of principal energy levels.

• The rare earth elements are divided into lanthanides (similar to lanthanum) and actinides (similar to actinium).

• Rare earth elements are metallic in nature but less abundant compared to other elements.
