The s-block of the Periodic Table of elements consists of the first two groups: the alkali metals and alkaline earth metals, plus hydrogen and helium.
These elements are distinguished by the property that in the atomic ground state, the highest-energy electron is in an s-orbital. Except in hydrogen and helium, these electrons are very easily lost to form positive ions. The helium configuration is chemically exceedingly stable and thus helium has no known stable compounds; thus it is generally grouped with the noble gases.
The other elements of the s-block are all extremely powerful reducing agents, so much so that they never occur naturally in the free state. The metallic forms of these elements can only be extracted by electrolysis of a molten salt, since water is much more easily reduced to hydrogen than the ions of these metals. Sir Humphry Davy, in 1807 and 1808, was the first to isolate all of these metals except lithium, beryllium, rubidium and caesium. Beryllium was isolated independently by F. Wooler and A.A. Bussy in 1828, while lithium was isolated by Robert Bunsen in 1854, who isolated rubidium nine years later after having observed it and caesium spectroscopically. Caesium was not isolated until 1881 when Carl Setterberg electrolysed the molten cyanide.
The s-block metals vary from extremely soft (all the alkali metals) to quite hard (beryllium). With the exception of beryllium and magnesium, the metals are too reactive for any structural use except as very minor components (<2%) of alloys with lead. Beryllium and magnesium, though very expensive, are valuable for uses that require strength and lightness. They are extremely valuable as reducing agents to extract titanium, zirconium, thorium and tantalum from their ores, and have other uses as reducing agents in organic chemistry.
All the s-block metals are dangerous fire hazards which require special extinguishants to extinguish, except for beryllium and magnesium, storage must be under either argon or an inert liquid hydrocarbon. They react vigorously with water to liberate hydrogen, except for magnesium, which reacts slowly, and beryllium, which reacts only when amalgamated with Mercury to destroy the oxide film. Lithium has similar properties to magnesium due to the diagonal relationship with magnesium in the periodic table.
What else can I help you with?
What are the different blocks on the periodic table and how do they contribute to the organization of elements?
The periodic table is divided into four main blocks: s-block, p-block, d-block, and f-block. These blocks help organize elements based on their electron configurations and properties. The s-block elements are found in groups 1 and 2, the p-block elements are in groups 13-18, the d-block elements are in groups 3-12, and the f-block elements are the lanthanides and actinides. Each block represents a different type of electron orbital and helps to group elements with similar chemical properties together.
Is elements in the s and p blocks of the periodic table called transition metals?
No, elements in the s and p blocks of the periodic table are not called transition metals. Transition metals are a group of elements located in the d-block of the periodic table. Elements in the s and p blocks have different properties compared to transition metals.
What does p mean in the periodic table?
In the periodic table, p refers to the p-block of elements. These elements include groups 13-18 (IIIA-VIIIA) and are characterized by the electron configuration in their outermost energy level containing p orbitals. The p-block elements are diverse in their properties and form a wide range of compounds.
Why periodic table is divided in s p d and f block elements?
The s, p, d, f block realte to the filling of the outer shell orbitals. Group 1 and 2 are the s block. Groups 13-18 the p block, the transition metals the d block and the lanthanides and actinides the f block.
Which statement best explains why the elements in groups 13 to 18 of the periodic table are called p-block elements?
These elements are called p-block elements because their outermost electrons are in the p orbital. In the groups 13 to 18, the electrons fill the p sublevel in the outermost energy level of the atom, which gives these elements their unique properties.

No, elements in the s and p blocks of the periodic table are not called transition metals. Transition metals are a group of elements located in the d-block of the periodic table. Elements in the s and p blocks have different properties compared to transition metals.

In the periodic table, p refers to the p-block of elements.

The p-block elements are diverse in their properties and form a wide range of compounds.
Why s-block and p-block elements are called Representative Elements?
P-block elements can be metals, metalloids, or nonmetals whiles S-block elements are all metals. P-block elements can be either gases or solids while S-block are all solids. and each P-block elements displays a greater range of properties.
Why periodic table is divided in s p d and f block elements?
The s, p, d, f block realte to the filling of the outer shell orbitals. Group 1 and 2 are the s block. Groups 13-18 the p block, the transition metals the d block and the lanthanides and actinides the f block.
What elements belong to the p block?
Elements which have their valency electrons in the p sub shell belong to this. Elements of groups 13,14,15,16,17,18 are in p block.
What are the majority of the elements in the p-block classified as?
The majority of the elements in the p-block are non-metals.
Which statement best explains why the elements in groups 13 to 18 of the periodic table are called p-block elements?
These elements are called p-block elements because their outermost electrons are in the p orbital. In the groups 13 to 18, the electrons fill the p sublevel in the outermost energy level of the atom, which gives these elements their unique properties.
What is an element in the s block or p block of the periodic table?
An element in the s block of the periodic table includes metals like sodium and potassium, while an element in the p block includes nonmetals like oxygen and nitrogen. These elements are characterized based on their outer electron configuration, which determines their chemical properties and reactivity.
Why is bromine a p block element?
Bromine is a p-block element because its outermost electrons are in the p orbital of its valence shell. It is located in group 17 of the periodic table, known as the halogens, which are nonmetals with similar chemical properties due to their electron configuration. Bromine's properties and behavior align with other p-block elements in the periodic table.
What section of the periodic table includes the s block and p block?
The s block and p block elements are located in the main group elements of the periodic table. The s block elements are in groups 1 and 2, while the p block elements are in groups 13 to 18. These elements are located on the left and right sides of the periodic table, respectively.
How many elements fit into each of the four blocks of the periodic table?
4: the s-block, the p-block, the d-block, and the f-block. there is an theoratical g-block but its not counted because its theoratical lol.
