Answer:
The p-block elements are found on the right side of the periodic table. They include the boron, carbon, nitrogen, oxygen and flourine families in addition to the noble gases. The noble gases have full p-orbital's and are nonreactive.
The s-block elements of the Periodic Table are those in
which the last electron enters the outermost s-orbital. As
the s-orbital can accommodate only two electrons, two
groups (1 & 2) belong to the s-block of the Periodic Table.
Group 1 of the Periodic Table consists of the elements:
lithium, sodium, potassium, rubidium, caesium and
francium. They are collectively known as the alkali metals.
These are so called because they form hydroxides on
reaction with water which are strongly alkaline in nature.
The elements of Group 2 include beryllium, magnesium,
calcium, strontium, barium and radium. These elements
with the exception of beryllium are commonly known as
the alkaline earth metals. These are so called because their
oxides and hydroxides are alkaline in nature and these
metal oxides are found in the earth’s crust*.
Answer:
- S-block Elements: S-block elements have the common electron configuration of [noble gas]ns1 (for group I elements) and [noble gas]ns2 (for group II elements).
- P-block Elements: P-block elements have the common electron configuration of [noble gas]ns2 np1-6. But, helium has 1s2 configuration; it is a special situation
- S-block Elements: S-block elements do not show multiple oxidation states like p-block elements. For example, the group I elements show +1 oxidation state and group II elements show +2 oxidation state.
- P-block Elements: Unlike the s-block elements, p-block elements have a common oxidation state for their respective group in the periodic table and some other additional oxidation states depending on the stability of the ion.
- S-block Elements: In general, all the s-block elements are metals. They are shiny, good electrical and heat conductors and easy to remove electrons from valence shell. They are the most reactive elements in the periodic table.
- P-block Elements: Most of the p-block elements are non-metals. They have low boiling points, poor conductors and difficult to remove electrons from the outermost shell. Instead, they gain electrons. Some of the non-metals are solids (C, P, S, Se) at room temperature while some are gases (Oxygen, Nitrogen). Bromine is a non-metal, and it is a liquid at room temperature.
