the elements belonging to group 1 and 2 of the Periodic Table are s-block elements. it includes elements in which the outermost subshell is s and that have 1 or 2 electrons in their outermost shell.

∙ 11y agoYour s-block elements are the ones in groups 1 and 2. These two groups have their outermost electrons in the s sublevel. Group 1 has an electron configuration that will end in s1, and group 2 has an electron configuration that will end in s2. Group 1 is somewhat more reactive than group 2 due to lower ionization energies; in fact, group 1 elements are so reactive that they do not exist by themselves in nature.
Group 1: H, Li, Na, K, Rb, Cs, Fr; group 2: Be, Mg, Ca, Sr, Ba, Ra.

Where is the s block located in the periodic table?
On a periodic table, the "s-block" is the first columns. The elements in the first column have 1 s-electron, and those in the second have 2.
Are in the s and p blocks of periodic table?
s-block elements: groups 1 and 2 p-block elements: groups 13 to 18
What groups comprise each block of elements in the periodic table?
s block elements: groups 1-2 d block elements: groups 3-12 p block elements: groups 13-18
What are the 4 main groups on the periodic table?
S block elements- valence electrons are filling the s orbitals D block elements- valence electrons are filling the d orbitals P block elements- valence electrons are filling the p orbitals F block elements- valence electrons are filling the f orbitals
Is elements in the s and p blocks of the periodic table called transition metals?
No the p block of elements does not contain transition metals. The lowest energy level to allow d orbitals is not the fourth energy level.
What block of the periodic table is the biggest?
s block and especially group 1 elements.
Where is the s block located in the periodic table?
On a periodic table, the "s-block" is the first columns. The elements in the first column have 1 s-electron, and those in the second have 2.
What elements belong to the s-block of the periodic table?
Elements in group no.(verticle) 1&2
What is an element in the s block or p block of the periodic table?
The elements in Groups 1 and 2 are in the s block. The elements in Groups 13-18 are in the p block.
What is the first column on the left of the periodic table is called?
alkali metals / s block elements
What can the vast majority of elements in the periodic table be classified as?
The vast majority of elements in the periodic table can be classified as metals. Metals make up the s-block, d-block, and f-block of the periodic table. There are even a few elements in the p-block with metallic properties called metalloids.
Are in the s and p blocks of periodic table?
s-block elements: groups 1 and 2 p-block elements: groups 13 to 18
What are in the s- and p-blocks of the periodic table?
s-block elements: groups 1 and 2 p-block elements: groups 13 to 18
Which periodic table family consists of highly-reactive elements?
S block has the most reactive elements. The groups 1 and 2 belongs to the s block.
What is the first block on the periodic table called?
The first block on the periodic table is called the S block.
What groups comprise each block of elements in the periodic table?
s block elements: groups 1-2 d block elements: groups 3-12 p block elements: groups 13-18
What is the definition of block in periodic table?
In the periodic table elements having valence electrons in the same orbital are said to be placed in the same block.There are four blocks in the periodic table s, p, d and f.
