Yes, this affirmation is true.
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
Elements in the same group have similar properties. The groups are made according to the properties of elements. Elements in a group have an equal number of valence electrons.
Elements in the same group have similar physical and chemical properties.
Elements in the same group have similar properties because they have the same number of valence electrons. In contrast, elements in the same period do not necessarily have similar properties, as their chemical behavior is determined by the number of electron shells they have.

family
Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
a group of elements that have similar properties are arranged one on top of the other on the periodic table. These groups are also called families
elements in the same group
Elements in the same group or column on the periodic table have similar properties. This is because they have the same number of valence electrons, which determines their chemical behavior. For example, all elements in Group 1 (such as lithium, sodium, potassium) share similar properties due to having one valence electron.
The group. Elements in the same group tend to have similar properties.
The chemical elements in a group have similar properties.
