How are p-block elements classified?
Based on the composition of electron orbitals, hydrogen, helium and Group 1 elements are classified as s-block elements, Group 13 through Group 18 elements p-block elements, Group 3 through Group 12 elements d-block elements, and lanthanoid and actinoid elements f-block elements.
What does p-block contain?
The p-block contains groups 13, 14, 15, 16, 17, and 18, with the exception of Helium. (Helium is part of the s block.) The principal quantum number “n” fills the p orbital. There is a maximum of six electrons that can occupy the p orbital.
What are the main features of p-block elements?
P-block metals have classic metal characteristics: they are shiny, they are good conductors of heat and electricity, and they lose electrons easily. Generally, these metals have high melting points and readily react with nonmetals to form ionic compounds.
What are the uses of p-block elements?
Uses of p-block Elements
- A compound of boron called borax is used in the glass making industry and pottery.
- Boron is also used in the soap or detergent industry.
- Boron is used in aircrafts and bullet proof vests.
- Boron is used in steel to increase its hardness.
What are the characteristics of p block elements?
Characteristics of p-Block Elements 1 The general electronic configuration of p-block elements is ns2np1-6(except He). Whereas the inner core electronic… 2 The oxidation state of elements in p – block is maximum when it is equal to a total number of valence electrons i.e. the… More
Can a p block metal melt in your palms?
It is a p block metal that can actually melt in your palms. On the other hand p block elements also have silicon that is a metalloid. It is a very important component in the making of glass. A prominent characteristic of these p block elements is that the last electron of all these elements enters the outermost p-subshell.
Are there any metalloids in the p block?
Metalloids have properties of both metals and nonmetals, but the term ‘metalloid’ lacks a strict definition. All of the elements that are commonly recognized as metalloids are in the p-block: boron, silicon, germanium, arsenic, antinomy, and tellurium. Silicon is perhaps the most famous metalloid.
Is the element helium included in the p block?
Helium, which is in the top of column 8A, is not included in the p-block. In the periodic table shown here, the p-block is colored orange. P-block elements are unified by the fact that their valence electrons (outermost electrons) are in the p orbital.
