You are watching: Where are the representative elements located
The long form of the periodic table consists of four blocks:
This group is based on the presence of valence electrons at a certain power level. The s-block elements and also p-block aspects are also known as representative elements. The noble gases put in the 18th group the the periodic table space not part of representative elements.
The representative facets have completely filled inside orbitals and incomplete outer orbitals or valence shells. This why they often tend to obtain the nearest noble gas configuration either by move or share of an electron with other atoms.

The elements in the periodic table room arranged into 4 blocks: s, p, d, and f. The facets present in s- and p-blocks are collectively known as representative facets or main team elements.
These elements have filled inner orbitals and incomplete outermost orbitals or valence shells. All non-metals and a few metals are part of the representative elements or main team elements.
The noble gas elements placed in the 18th group of the long form of the periodic table room not component of the representative elements because they have filled valence shells and they do not tend to share or transfer electrons for the link formation.
All these facets tend to kind either a covalent bond or an ionic bond. The ionic bonds result by the complete move of electrons, whereas covalent bonds are created by same sharing that electrons in between the external inspection atoms.
Following is a perform of the representative elements:
Group 1 (s-block element):
Group 1 facets are likewise called as alkali metals because their oxides form an alkaline solution. They are metallic and also tend come form an ionic shortcut by lose of 1 valence electron. Lithium, sodium, potassium, rubidium, and cesium are considered alkali metals.
Group 2 (s-block elements):
Group 2 elements are also called alkaline earth metals as their oxides kind alkaline solution and are mainly discovered in the Earth's crust. They room metallic and also tend to form an ionic shortcut by lose of 2 valence electrons. Alkaline planet metals room beryllium, magnesium, calcium, strontium, and barium.
Group 13 (p-block elements):
Group 13 facets are metallic elements with some of the metalloids. Metalloids space the aspects with intermediate properties of metal and non-metal. In this group, boron is a metalloid whereas every other elements are metals.
Group 14 (p-block elements):
Group 14 elements are a mixture the non-metallic and metallic elements with some of the metalloids. C is the just non-metal of this group with Si and also Ge being metalloids. Other elements (Pb and also Sn) are metallic aspects of this group. They have actually 4 valence electrons and tend to expropriate 4 electron to obtain octet.
Group 15 (p-block elements):
Group 15 facets are a mixture the non-metallic and also metallic elements along with some metalloids. Nitrogen and Phosphorous are non-metals of this group. Arsenic and antimony are metalloids. Bismuth is a metallic facet of this group. They have 5 valence electrons and tend to accept 3 electrons to complete their octet.
Group 16 (p-block elements):
Group 16 consists of non-metals, metals, and metalloids. Oxygen, sulfur, and selenium are non-metals of this group. Tellurium is a metalloid. Polonium is a metallic aspect of this group. They have actually 6 valence electrons and tend to accept 2 electrons to complete their octet.
Group 17 (p-block elements):
All the facets present in group 17 are non-metals. These elements are also called halogens and have 7 electrons in your valence shell. These aspects complete their octet by acquiring or sharing one electron. Elements of group 17 space fluorine, chlorine, bromine, iodine, and astatine.
Group 1 and also group 2 facets are metals and mostly form an ionic bond. They are great conductors that heat and electricity. They kind basic oxides which are usually colorless and also soluble in water.
Group 1 and group 2 facets are highly reactive. Hence, they react violently through water and also oxygen.
Group 1 and group 2 aspects exist in solid state.
Group 13 come group 17 facets are a combination the metals, metalloid, and non-metals. They form an ionic bond with metals and a covalent link with other non-metals.
Most the the non-metals exist in gas state, but some are also solid and liquid.
