Chemical elements that are in the same group within the periodic table have the same numbers of electrons in the outermost shell.

This gives them similar reactivity.

Why are elements in the same group undergo the same kinds of reactions?

Elements in the same group have similar chemical properties because they have the same number of valence electrons, which determines how they interact with other elements. This leads to similar reactivity patterns among elements within the same group.


The elements within a group have a similar number of?

Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.


Why do we say that elements within a group act alike?

The chemical elements in a group have similar properties.


What is the same within each group on the periodic table?

Elements within the same group on the periodic table have the same number of valence electrons, which influences their chemical behavior. This results in similar properties and reactivity within a group of elements.


What do the elements in groups columns of the periodic table have in common?

Elements in the same group of the periodic table have similar chemical properties due to having the same number of valence electrons. This leads to similar reactivity and bonding behavior within a group of elements.


Why do all the member of a group of elements have similar properties?

All the members of a group of elements have similar chemical properties because they all have the same number of electrons in their valence bands. The periodic table of elements is arranged this way, that is, by electron structure. The vertical columns are the groups of elements, and it is their electron structure that places them where they are.


What do elements in the same group in the periodic table have in common?

They have the same number of valence electrons, or electrons in the outer electron shell. This allows them to react with certain elements.


Why do elements in a group all behave similarly?

Elements in the same group behave similarly because they all have the same number of electrons in their outer-most orbits. These electrons are what determines the types of bonds and chemical reactions the atom can undergo.


Do elements in the same group have similar atomic numbers?

Elements in the same group have similar chemical properties but not necessarily similar atomic numbers. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical properties.
