Because they all have the 2 electrons in their outer shell.
Elements with similar physical and chemical properties are located in a group.
Elements in the same group (column) have the same properties. All the elements in group one have similar properties. All the elements in group two have similar properties. And so on...
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.
it is the ~group~ of the periodic table of elements
A group of elements.
Elements of same group have the same number of valence electrons and hence have similar 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 that have similar chemical properties occupy the same group on the Periodic Table.
...chemical properties.
No. All elements in a same group have the same number of valence electrons and hence have similar properties.
Elements with similar properties occur within the groups(columns) on the periodic table.Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
a group of elements that have similar properties are arranged one on top of the other on the periodic table. These groups are also called families
