Families on the periodic table include, in addition to noble gases and halogens, the alkali metals, alkaline earth metals, transition metals, lanthanides, and actinides. The nonmetals form a loosely defined cross-family grouping, as do the metalloids.

How many element families are there?

How are elements in group 8 different from all other elements in the periodic table?
8th group or 18th group element are called as NOBLE GASES . These are the elements starting from He(Helium) and ending at Og(Ogenesson),they are least reactive due to their octet electronic configuration. This property makes them different from other elements of periodic table.Sep 29, 2020

What is a chemical family?
A family of chemical elements usually consists of elements in the same group (the same column) on the periodic table. The term is also applied to certain closely related elements within the same period (row). Just as the individual members in a human family are different but have common characteristics, such as hair color, the elements in a chemical family have certain properties in common, and others that make them unique.
How are lanthanides and actinides related?
The lanthanides (or rare-earth elements) and actinides are two families that are related because they both result from electrons being added into an f sub-level. Both families have 14 members, the lanthanides consisting of the elements with atomic numbers 58 through 71, and the actinides including the elements with atomic numbers 90 through 103. However, it is sometimes convenient to consider lanthanum ( atomic number 57) as an honorary member of the lanthanide family and to treat actinium ( atomic number 89) in a similar manner with respect to the actinides.
Who was the first to organize elements into families?
D ö bereiner (1780 – 1849) made one of the earliest attempts to organize the elements into families in 1829, when he observed that for certain groups of three elements, called triads, the properties of one element were approximately midway between those of the other two. However, because the number of elements known to D ö bereiner was far fewer than it is today, the number of triads that he was able to find was very limited.
Is hydrogen a family?
When the elements are organized into families, hydrogen presents a problem. In some of its properties, hydrogen resembles the alkali metals, but it also shows some similarities to the halogens. Many periodic tables include hydrogen in group 1; others show it in groups 1 and 17. An alternative approach is to recognize hydrogen as being unique and not to assign it to a family.
What are the elements in the transition metal family?
At least two small family units can be identified within the larger transition-metal family. One of these small families, the coinage metals, consists of copper, silver and gold, the three elements in group 11. The other family, the platinum metals, includes elements from three groups: ruthenium and osmium from group 8; rhodium and iridium from group 9; and palladium and platinum from group 10.

- The Basics of the Periodic Table
Created in 1869, and modified several times since then, the periodic table of the elements developed by Russian chemist Dmitri Ivanovitch Mendeleev (1834-1907) provides a highly useful means of organizing the elements. Certainly other organizational systems exist, but Mendeleev'…

The Transition Metals
- For those families of elements found among the main group elements, that is, elements in groups 1 and 2, and 13 through 18 of the periodic table, each member of a given family has the same number of valence electrons. A detailed examination of the electron configurations of the elements in these families reveals that each family has its own characteristic arrangement of el…
The Coinage Metals and The Platinum Metals
- When the elements are organized into families, hydrogen presents a problem. In some of its properties, hydrogen resembles the alkali metals, but it also shows some similarities to the halogens. Many periodic tables include hydrogen in group 1; others show it in groups 1 and 17. An alternative approach is to recognize hydrogen as being unique and not to assign it to a family.
The Lanthanides and Actinides
- In addition to the main-group families, other families of elements can be identified among the remaining elements of the periodic table.

- The elements in groups 3 through 12, the transition metals or d -block elements, could be considered as one large family. Their characteristic feature, with some exceptions, is the presence of an incomplete dsublevel in their electron configurations. As with any large family, transition metals show considerable diversity in their behavior, although there are some unifying features, …
