Same elements of group have same valency. They possess same chemical behaviour.
Copper, gold, and silver are the choices that represent a group of elements with common characteristics. All of these elements are metals.
they have the same number of outer electrons
All elements in Group 7 have the same number of electrons in their outermost shell and this number corresponds to the group number.
Valence electrons for elements in the same group are the same because they are located in the outermost energy level of an atom. This common number of valence electrons is what gives elements within a group similar chemical properties.
Not sure what the command is but a characteristic which is common is that they have the same number of valency electrons.
All elements in a group have same chemical properties. They have same number of valence electrons.
All elements in the same A group will have the same number of valence electrons.
All elements in the groups (excluding transition metals) have the same number of electrons as the group number.
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.
Elements that are contained within the same column in the periodic table are known as a group. All of the elements in the first group of the table have one electron in their outer shell.
Elements with the same number of valence electrons are found in the same group or column of the periodic table. This is because elements in the same group have the same number of valence electrons, which determines their chemical properties. For example, all elements in group 1 have 1 valence electron.
All elements in the same group have the same number of valence electrons.
