Iron Triad (iron,cobalt,nickel)
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
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) .
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 have similar physical and chemical properties.
Elements with the most similar physical and chemical properties are found in the same group or column of the periodic table. Each group contains elements that share common characteristics, such as reactivity, electronegativity, and atomic structure. For example, the alkali metals in Group 1 are highly reactive and have similar properties, as do the noble gases in Group 18, which are known for their lack of reactivity.
These elements have similar chemical and physical properties.

Elements in the periodic table with similar qualities are grouped together in columns called groups or families. Elements within the same group share similar chemical properties because they have the same number of valence electrons. This allows them to react in similar ways with other 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.
They have the same number of valence electrons and so have similar reactivity and similar properties.
The elements in a group have the similar chemical properties dueto presence of same no of electrons in their outermost shell but they differ physically because physical properties are related to their atomic sizes from top to bottom in a group atomic size increases so their physical properties also differ.
Elements in the same family-assuming family means classifications such as non-metals, metals-have similar properties.
True. Mendeleev organized the elements into the periodic table based on their atomic weight and similar chemical properties. He noticed that elements with similar properties tended to occur at regular intervals, leading to the periodicity of the elements.
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.
Both elements, sodium (Na) and potassium (K) lie in the Group 1 column of the Periodic Table , which contains the members of the Alkali Metals family. Members within a family, or column, of elements tend to have similar chemical properties.
Families of elements with similar chemical properties are called "groups" or "families" on the periodic table. Elements within the same group typically have the same number of valence electrons, which gives them similar reactivity and chemical properties.
