they are responsible for eletronegativity, ionic/covalent bonding, and it's basic properties ie: melting point for metals
yes
along with the number of electrons present in the (valence) shell / orbitals

This is rightThe outermost electrons account for many of the physical and chemical properties of elements.
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.
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.
Chemical properties of an element determine by the number of electron

Electrons.
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.
