They don't have one. Group 8 is noble gasses.
1) Stable Atomic structure.
2) Does not bond with any other elements.
3) Exist as mono-atomic elements.
elements in the same group as nitrogen will have similar CHEMICAL properties because they have the same number of electrons in the outer shell. (this is according to Bohrs model of the atom, if you want a real confusing answer about valence shells etc. go look at quantam mechanics) So elements in group 7 are phosphurus, arsenic, selenium, tellurium, polonium, these will react with the same chemicals to from similar compounds however they are all solids unlike nitrogen. Elements with similar PHYSICAL properties are elements that are present as gases at room temperature (like nitrogen is) oxygen, fluorine, chlorine, hydrogen and all of group 8 the noble or inert gasses (although inert isn't really a valid term as they can react in the correct conditions)
Groups 3-12 have elements with the most diverse set of properties in the periodic table. They are transition elements.
Neon - one of the stable and unreactive elements of group 8.
The elements in group 8 of the periodic table are iron (Fe), ruthenium(Ru), osmium(Os), and hassium(Hs). All four of these elements are grouped together because each of their atoms has a full valence shell containing the maximum of 8 electrons. Atoms seek to bond when their outer valance is unstable and has less than 8 electrons. Their goal is to fill the valance with 8 electrons to become chemically unable to bond or "chemically inert." That is the case with the group 8 elements. They have a complete or closed shell and that is why they do not bond with other elements.
The elements in the 8 main columns of the Pperiodic Table are called Groups. Groups 1 and 2 are separated from Groups 3 to 8 by a block of elements called the Transition Series and the columns in this series have no specific names.
The arrangement of chemical elements in groups and periods is determined by the periodicity of the chemical properties. In the case of the transition state elements, there are some smaller groups because of the way the incomplete inner electron shells are filled.

All the elements in the same group have similar properties because the have the same number of valency electrons. Same is the case with group ) elements they have the same number of valency electrons which is 8 so that's why the =y have similar properties
Depending on the block it may be increasing or decreasing acidity, atomic radii varies through periods, atomic number increases by 1 with each element, ... as to reactivity, elements of lower periods are almost all radioactive, as with a heavier nucleus nuclear stability decreases. Hope this answers your question! :D
Generally, if you look down a group of the periodic table, they all share similar characteristics (groups 1-8). The transition metals and lanthanides and actinides can vary
One can show that elements that have different appearances have similar chemical properties by showing their placement on the periodic table. The table is arranged by chemical families that have similar characteristics.
You think probable to group 8: copper, silver, gold.
Because they have the same number of valency electrons , which is 8 , and the same "Inert" chemical properties .
That some had the same among of Protons and Neutrons. That each coumn had a preiod!
Rubidium (Rb) can react with many things such as hydrogen because rubidium has one spare electron 2, 8, 18, 8, 1 and hydrogen has only one outer electron so hydrogen in water will reactvigorously with rubidium as hydrogen is desperate to gain one electron and rubidium is desperate to lose one electron and when these bond they form an ion.
The properties were repeated after 8 elements.
