Because no two elements are exactly alike. For instance, gold and silver may both be in the transition metal group and have similar properties like rust resistance and conductivity, but they have different melting points (gold 1356 kelvin, silver 1241 kelvin) for instance.
They have different numbers of valance electrons...
Element X is located on the periodic table based on its atomic number and chemical properties. By knowing the atomic number of element x, you can determine its specific location within the periodic table.
The periodic table tells you that elements in the same group have similar chemical properties because they have the same number of valence electrons. This influences how they react with other elements and helps predict their behavior in compounds.
Silicon, carbon's only neighbor within its periodic table column 14.
The properties of an element are primarily determined by its atomic structure, specifically the number of protons, neutrons, and electrons in its atoms. The arrangement of these particles within the atom dictates characteristics like atomic number, mass number, and electron configuration which in turn influence the element's physical and chemical properties. Additionally, the element's position on the periodic table, or its group and period, also plays a key role in defining its properties.
Elements present within a same group normally have similar properties
Elements in group A are metals. They possess metallic behaviour.

Element X is located on the periodic table based on its atomic number and chemical properties. By knowing the atomic number of element x, you can determine its specific location within the periodic table.
Element within a group have nuclei of different sizes so that their valency electrons are at different distances from the nuclei. This affects their electronegativity and thence other chemical properties.
Periodicity on the periodic table refers to the repeating pattern of physical and chemical properties of elements as you move across or down the table. This periodic pattern is a result of the elements having similar outer electron configurations within the same group or period. Periodicity helps to predict an element's properties based on its position in the periodic table.
To find an element that is similar to another element, look in the periodic table and find an element in the same column (group/family) as the element of interest. Usually, elements within the same group/family have very similar properties.
The periodic table tells you that elements in the same group have similar chemical properties because they have the same number of valence electrons. This influences how they react with other elements and helps predict their behavior in compounds.
The atomic number of an element is the number of protons in the nucleus of an atom of that element. It is represented by the symbol "Z" on the periodic table. The atomic number determines the element's identity and its unique properties.
The periodic trends that arise from the arrangement of the periodic table provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or period and the periodic nature of the elements.
