Question: What are the 9 families in the periodic table?

9 Element Families

  • Alkali Metals: Group 1 (IA) – 1 valence electron.
  • Alkaline Earth Metals: Group 2 (IIA) – 2 valence electrons.
  • Transition Metals: Groups 3-12 – d and f block metals have 2 valence electrons.
  • Boron Group or Earth Metals: Group 13 (IIIA) – 3 valence electrons.

What are the families of the periodic table?

Families of the Periodic Table. On the periodic table, there are families which are groups of elements with similar properties. These families are alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, halogens, noble metals, and noble gases.

How many a families are there in the periodic table?

So why do the elements in the same family have similar properties? You can examine four families on the periodic table and look at the electron configurations for a few elements in each family. The figure below lists some important families that are given special names: The IA family is made up of the alkali metals.

What are the 8 groups on the periodic table?

The following are the 8 groups of the periodic table:

  • Alkali metals.
  • Alkaline earth metals.
  • Rare earth metals.
  • Crystallogens.
  • Pnictogens.
  • Chalcogens.
  • Halogens.
  • Noble gases.

What are the 10 groups of the periodic table?

Terms in this set (10)

  • Alkali metals. Alkali metals Group 1: very reactive metals which do not occur freely in nature.
  • Alkaline Earth Metals. Group 2: next reactive metals, found in earths crust but not in elemental form.
  • Transition Elements.
  • Lanthanides and Actinides.
  • Boron Group.
  • Carbon Group.
  • Nitrogen Group.
  • Oxygen Group.

What family is Group 18?

The noble gases (Group 18) are located in the far right of the periodic table and were previously referred to as the “inert gases” due to the fact that their filled valence shells (octets) make them extremely nonreactive. The noble gases were characterized relatively late compared to other element groups.

What family has 7 valence electrons?

Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.

What are the three families of elements?

Recall that all elements can be classified into three categories: metals, nonmetals, and semiconductors. Scientists classify the elements further into five families. The atoms of all elements in most families have the same number of valence electrons.

How many groups are there in the periodic table?

Groups are numbered from 1 to 18. From left to right in the periodic table, there are two groups (1 and 2) of elements in the s-block, or hydrogen block, of the periodic table; ten groups (3 through 12) in the d-block, or transition block; and six groups (13 through 18) in the p-block, or main block.

How many families are in the periodic table list them and group number?

The s-, p-, and d-block elements of the periodic table are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.

What are the 7 groups of the periodic table?

What are the 7 groups in the periodic table

  • The Alkali Metals.
  • The Alkaline Earth Metals.
  • The Transition Metals.
  • The Metalloids.
  • Other Metals.
  • The Non-metals.
  • The Halogens.
  • The Noble Gases.

How many groups families and period does a periodic table have?

The elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups.

What are groups 3 12 on the periodic table?

The elements from Group 3 to 12 are called Transition Metals. They include the Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, and Zinc families of elements. Transition Metals are hard and dense, are good conductors of heat and electricity, and can be bent easily.

What are the 5 main groups of the periodic table?

5 Element Families

  • Alkali metals.
  • Alkaline earth metals.
  • Transition metals.
  • Halogens.
  • Noble gases.
