Homologise have the different molecular masses so can not have the same physical properties, due to same functional group they show same chemical properties but with different rates of reaction.
Chemical properties of a element is governed by ELECTRONIC CONFIGURATION of that element. As isotopes of same element have identical electronic configurations, their chemical properties are same.
A chemical change occurs when substances show new properties. This involves a rearrangement of atoms leading to the formation of new chemical bonds, resulting in the creation of a new substance with different properties than the original substances.

The difference between a chemical property and a chemical change is that the change is how the property of the chemical changes when it undergoes a chemical reaction.

Atomic Weightsthey have same number of valence electrons and hence similar chemical properties.

1. They have the same general formula 2. They have similar chemical properties 3. They show a gradual change in their physical properties.
The chemical properties of an object show what a chemical change did to that substance.

Bromine and iodine are two elements that have properties similar to chlorine. They belong to the same group in the periodic table, known as the halogens, and share characteristics like reactivity and forming salts with metals.
Silicon.
The columns of the periodic table are known as 'groups'. Further, the elements in the same group almost show a same type of chemical behaviour.
The chemical properties of an object show what a chemical change did to that substance.
Silicon.
Members of the same vertical group on the periodic table have the same number of outer shell electrons, which determines their chemical reactivity. Similar chemical properties are seen because elements in the same group tend to form similar types of bonds and compounds due to their similar electron configuration. Additionally, they often display similar physical properties such as melting and boiling points because of their comparable atomic structures.
