periodic table
The scientist who observed the pattern of properties that repeated every eight elements was John Newlands. He created the Law of Octaves, which grouped elements based on similar properties and noted the repetition every eighth element.
The elements are arranged in the increasing order of their atomic number and repeating properties.
A scientist can find an element with properties similar to another by looking at elements in the same group or column of the periodic table. Elements in the same group tend to have similar chemical properties due to their similar outer electron configurations. This allows scientists to predict the behavior of an element based on its position on the periodic table.

Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.

These elements have similar chemical and physical properties.

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.
Russian scientist Dmitri Mendeleev first arranged the elements in the periodic table based on increasing atomic mass and similar properties. He left gaps for undiscovered elements and predicted their properties, which led to the discovery of new elements. Mendeleev's periodic table laid the foundation for the modern periodic table we use today.
They have the same number of valence electrons and so have similar reactivity and similar properties.
The scientist who proposed the law of octaves was John Newlands in 1864. He noticed that when the elements were ordered by atomic weight, every eighth element had similar properties, similar to the musical concept of octaves.
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.
