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.
By grouping the elements on 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.
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
See the link below fot the IUPAC model of the periodic table of elements.
The two divisions on the periodic table are called metal and nonmetal. The elements are either nonmetal or metal, and that is how they are divided
D block elements are at the center of the periodic table; f block elements are at the bottom.
because thats how the periodic table is
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.
the AR lies in P-block
The elements are arranged in order of increasing atomic number, which corresponds to the number of protons in the nucleus of an atom. Elements with similar properties are grouped together in columns called groups or families. The periodic table is divided into blocks: s-block, p-block, d-block, and f-block, based on the electron configuration of the elements. The periodic table is organized into periods or rows, which correlate with the energy levels or shells of the electrons of the elements.

Ag is the chemical symbol of silver, which is number 47 on the periodic table.
The f-block elements (lanthanides and actinides, the two rows at the bottom of the periodic table) are known as inner transition elements
