they are responsible for eletronegativity, ionic/covalent bonding, and it's basic properties ie: melting point for metals

Group number describes the number of valence electrons. It helps in estimating chemical properties of that element.For example-group-1 elements have 1 valence electronThe group number of an element is equal to the number of valence electrons. The number of valence electrons is responsible for the chemical properties. So the chemical properties of the element can be determined by the group number.
Valence electrons are the electrons that account for many of the chemical and physical properties of elements. These are the electrons in the outermost energy level of an atom and are involved in chemical bonding and reactions. The number of valence electrons determines an element's reactivity and ability to form compounds.
The chemical properties of the elements are chiefly due to the number and distribution of the outer electrons that they have.
Valence electrons are very important for the chemical properties of chemical elements; but all electrons have identical sizes.

These are the chemical properties.
An element's chemical properties are determined primarily by its electron configuration, which influences how it will react with other elements to form compounds. The number of protons in the atom's nucleus also plays a role in determining its chemical properties. Additionally, factors such as atomic size, electronegativity, and valence electrons contribute to how an element will interact chemically with other elements.

No. The properties of elements are determined by the number of protons, which in turn determines the number of electrons.
Elements in the same group have similar properties because they have the same number of electrons in their outermost shell.
Elements in the same group have similar properties as they have the same number of valence electrons.
