Is p Group 15?
nitrogen group element, any of the chemical elements that constitute Group 15 (Va) of the periodic table. The group consists of nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), and moscovium (Mc).
What are the p-block elements?
Consequently there are six groups of p–block elements in the periodic table numbering from 13 to 18. Boron, carbon, nitrogen, oxygen, fluorine and helium head the groups. Their valence shell electronic configuration is ns2np1-6(except for He). The inner core of the electronic configuration may, however, differ.
Is p-block easy chapter?
P block is a very scoring chapter. If you will give around 7-8 hours in these 3 days to these chapters only, then you might be able to complete it. On 1st day, you can study all the across and up to down rules and then start attempting the previous year questions.
Which block does Group 15 belong to?
All Group 15 elements have the electron configuration ns2np3 in their outer shell, where n is equal to the principal quantum number. The nitrogen family is located in the p-block in Group 15, as shown below.
Why is group 15 called P block?
Why is Group 15 called P block? It is a p-block element since it takes the physical and chemical properties after that of other p-block elements of the eighteenth group. P-block elements are generally non-metals, while the remaining are metalloids and metals.
What does the p-block mean?
p-block elements are those in which the last electron occupies p-orbitals and are found in groups 13, 14, 15, 16, and 17 (except helium). Because p-block orbitals can only hold a maximum of six electrons, p-block elements are classified into six groups. The first element of each group of p-block elements identifies it.
Why are they called p-block elements?
The s-block and p-block elements are so called because their valence electrons are in an s orbital or p orbital respectively. They are also called Typical Elements to distinguish them from the transition and inner transition series.
How do you remember the P-block elements?
To remember the trend, first arrange the elements in the order in which they are present in the group: B, Al, Ga, In, Tl. Next, switch the places of Ga and Tl – and you get the correct order of the melting point. There are different types of silicates and remembering them is important.
How many P-block groups are there?
Consequently there are six groups of p–block elements in the periodic table numbering from 13 to 18. Boron, carbon, nitrogen, oxygen, fluorine and helium head the groups. Their valence shell electronic configuration is ns2np1-6(except for He).
What are the properties of group 15 elements?
Periodic Trends in Group 15 Elements

Are group 15 elements metals?
Nitrogen family elements often form covalent compounds, usually with the oxidation numbers +3 or +5. Nitrogen and phosphorus are nonmetals. Arsenic and antimony are metalloids. Bismuth is a metal.
