Because the members of a group have the same number of valence electrons.
Elements in the same group or family have similar chemical properties because they have the same number of electrons in their outermost energy level. This leads to similar reactivity and bonding behavior. Additionally, elements in the same group often have similar physical properties, such as melting and boiling points.
Sulfur is in the oxygen family, also known as the chalcogens, because it shares similar chemical properties with oxygen and other elements in the group, such as tellurium, selenium, and polonium. These elements have six electrons in their outermost shell, which leads to similar bonding characteristics and chemical reactions.
Both elements, sodium (Na) and potassium (K) lie in the Group 1 column of the Periodic Table , which contains the members of the Alkali Metals family. Members within a family, or column, of elements tend to have similar chemical properties.
The elements in a group have the similar chemical properties dueto presence of same no of electrons in their outermost shell but they differ physically because physical properties are related to their atomic sizes from top to bottom in a group atomic size increases so their physical properties also differ.
Chemical properties. The classic example is the Group (I) Alkali metals, they all react with water., to produce the hydroxide, and liberate hydrogen gas. Here is the general equation 2M + 2H2O = 2MOH + H2 However in going down this Group , their reactivity with water becomes more violent, from genetle fizzing (Lithium) to explosive (Francium). Francium is not found in a lab. because it is also radio-active. Group (II) Alkaline Earth metals also have a similar property, but their reactivity is more genetle. M + 2H2O = M(OH)2 + H2
Elements in the same family-assuming family means classifications such as non-metals, metals-have similar properties.
Elements in the same family of the periodic table have similar bonding properties because they have the same number of valence electrons. This results in similar chemical reactivity as they tend to gain, lose, or share electrons in a similar manner to achieve a stable electron configuration. The shared valence electron configuration leads to similarities in their bonding behavior.
Elements in the same family, or group, have similar physical and chemical properties.
family
family
Family of elements share similar chemical properties due to having the same number of valence electrons. This results in comparable reactivity and bonding patterns within a group of elements. Additionally, they often exhibit a trend in physical properties such as atomic size and electronegativity.
Elements in the same group or family have similar chemical properties because they have the same number of electrons in their outermost energy level. This leads to similar reactivity and bonding behavior. Additionally, elements in the same group often have similar physical properties, such as melting and boiling points.
Elements from a family have similar chemical properties.
similar chemical properties and characteristics

Elements in the same family or group of the periodic table have similar properties because they have the same number of valence electrons, which determines their chemical behavior and bonding patterns. This similarity in electron configuration leads to comparable reactivity, ionization energy, and electronegativity among the elements. As a result, elements within the same group often exhibit analogous physical and chemical characteristics.
