group
There are 18 periods in the periodic table. The periods are divided according to the chemical properties of elements. Elements in a group have similar properties.
There are 18 families. They are made according to the properties of elements. So the elements in a group has similar properties.
Elements with similar properties are usually located in the same Group (column) on the Periodic Table.
The two elements likely have many similar properties due to their placement in the same group or column of the periodic table, which indicates they have the same number of valence electrons. This commonality leads to similar chemical reactivity and bonding behavior. Additionally, their atomic structures are comparable, resulting in analogous physical properties such as melting and boiling points. Overall, their shared electronic configurations contribute significantly to their similarities.
It is the interval between chemical elements, measured by the number of protons in its nucleus, at which many of the chemical properties are similar.
Nobelium is a member of the actinoids group an have many properties similar to these elements; also is supposed that nobelium is similar to ytterbium.
There are 18 families. They are made according to the properties of elements. So the elements in a group has similar properties.
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.

Because they have many similar chemical properties.
Elements with similar properties are usually located in the same Group (column) on the Periodic Table.
I guess, the most fundamental is their valency. This dictates how many times it can bond to other elements. Elements with the same valency often share similar properties with other elements with the same valency. The Periodic Table is divided into 8 rows (and a D block). Each of these 8 rows have elements with similar properties, related to their valencies.
Water is considered a pure chemical substance. Its mass and properties are similar to many of the other constituent elements.
It is helpful to organize things by characteristics because you can tell that certain elements are similar. For example if you knew nothing about the chemical or physical properties of (Rb) Rubidium, you could guess it has properties similar to (Cs) Cesium since they are in the same group. The common "Periodic Table" has many interesting forms. Search: "periodic table"
They don'tThey group elements with the same number of valence electrons.The valence electrons of an element determine how that element bond and how many bonds it forms.So elements with the same number of valence electrons tend to have similar chemical properties.
Elements are first organized by atomic number (left to right, top to bottom). They are organized into columns by their properties. The properties of an element are directly related to how many valence electrons that element has, so, with the exception of Helium, all of the elements in a column have the same number of valence electrons.
