Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
A tetravalent impurity refers to an impurity that introduces four valence electrons into a material's crystal lattice. These impurities can significantly impact the electrical and optical properties of the material due to their ability to alter the number of charge carriers within the material. Examples include elements like silicon or germanium in a crystal lattice of another material.
Number of valence electrons
The elements in each column of the periodic table have the same number of valence electrons. None of the other characteristics listed in the question is common to all these elements.
Look what column it is in within the Periodic Table. The first column has 1 valance electron. The second column has 2 valence electrons. The entire section of shorter columns (all metals) also have two valence electrons. The tall column after that (with Boron ) has three valence electrons. The tall column after that (with carbon) has four valence electrons. This pattern continues until you reach the final column, the noble gasses (eg. Neon, argon, xenon); these all have 8 valence electrons.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
electron valence hh
SiO2, also known as silicon dioxide, has a covalent bond. In silicon dioxide, silicon shares its four valence electrons with oxygen atoms, forming a network covalent structure. This results in a strong bond between silicon and oxygen atoms within the molecule.
there are five valence electrons in an atom of phosphorus

valence electrons
They have different numbers of valence electrons.
Valence electrons for elements in the same group are the same because they are located in the outermost energy level of an atom. This common number of valence electrons is what gives elements within a group similar chemical properties.
The elements in each column of the periodic table have the same number of valence electrons. None of the other characteristics listed in the question is common to all these elements.
Elements within the same period have the their valence electrons in the same principle energy level. For example, those elements in period 2, have their valence electrons in the 2nd energy level.
