This is rightThe outermost electrons account for many of the physical and chemical properties of elements.
Electrons in the valence shell or in the outermost shell of atoms determine the chemical behaviour.
NO electrons are such responsible. Most of the properties of an Atom are thoroughly and exclusively defined by the number of protons in the Atom's nucleus.
The outermost electrons, ( valence electrons)

chemical
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 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 group have same number of valence electrons and hence have similar chemical and physical properties.
When moving down a group, the number of valence electrons do not change. This similarity yields the elements in the same groups to have same chemical properties. For example, elements in group 17 obtain one electron to stabilize as -1 ion.In a group, all the elements have a same number of valence electrons. So their chemical properties are equal. But the physical properties vary.Valence electrons are the electrons in outermost shell.The valence electrons remain same in a group. For example-Group-1 elements have 1 valence electron.
chemical
Elements in the same group have similar properties as they have the same number of valence electrons.
These elements have similar chemical and physical properties.
They have the same number of valence electrons which, in general, gives them similar oxidation numbers and other similar chemical and physical properties.

Elements in a same group have same number of valence electrons and hence similar physical and chemical properties.
The elements in the same groups usually do. Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
Elements in a group have the same number of valence electrons and hence they have similar chemical and physical properties.
Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
The answer to, ' when repeating chemical and physical properties of elements change periodically with the elements' atomic numbers it is called the?'Periodic law, is the answer. PERIODIC LAW !orPeriodicity of the chemical elements properties.
