;need the same number of electrons to fill their valece shells
;have the same number of valence electrons
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 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.
You would likely find five elements with very similar properties in the same group of the periodic table. For example, elements in Group 1 (alkali metals) like lithium, sodium, potassium, rubidium, and cesium share similar characteristics such as being soft, highly reactive metals with low melting points and easily losing electron to form cations.
A group contains elements having similar properties because of the same number of valence electrons present in the atoms of those elements. So, of example if you take group one containing Lithium, Sodium, Potassium, etc, they all have similar properties because of having the same valency (+1) .
Any element in the alkali metal group would have similar chemical properties, for example they all react easily to water.

Group 1 elements, also known as alkali metals, have similar properties because they all have one electron in their outer energy level, making them highly reactive. This commonality results in similar atomic structures, reactivity, and chemical properties among the group members.
Elements that have similar chemical properties occupy the same group on the Periodic Table.
Iron , cobalt and Nickel families of periodic table show the similar properties. these families are in three different columns but are considered as one group.
They have the same number of valence electrons which, in general, gives them similar oxidation numbers and other similar chemical and physical properties. The similarities are most pronounced in the groups at either side of the standard periodic table, and are least pronounced for the transition and rare earth elements.

The groups each have different names. Group one is made up of Alkali Metals (except for Hydrogen). Group two is made of Alkali Earth Metals. The other groups include Transition Metals, Noble Gases, Poor Metals and Non Metals.
Any element in the alkali metal group would have similar chemical properties, for example they all react easily to water.
There is no fully objective answer to this question. Many chemists would consider that two lanthanide elements with atomic numbers differing by only one would be likely to qualify. Another possibility is the pair zirconium and hafnium. These are very similar in most chemical characteristics but differ greatly in electron capture tendencies in nuclear reactors.
Elements in the same group as cesium (Group 1, also known as the alkali metals) would have properties most similar to cesium. This group includes elements like rubidium and francium, which share similar chemical behaviors due to their one valence electron and tendency to form +1 cations.
