It can be bromine, chlorine, and potassium. Look for the Periodic Table and pick any one of those three elements.
Group are based on similar properties. The elements having same chemical properties are grouped together.
The elements are aranged in rows according to increasing atomic number. They are grouped in columns because they have similar chemical properties.
Classifying the elements make the study of elements easier. The elements with similar properties are grouped together.
Classifying elements make the study of elements easier. The elements with similar properties are grouped together.
The elements with similar properties are grouped together in families. They have same number of valence electrons.
They are grouped by similar characteristics
They react in similar ways.
Elements grouped in the same column exhibit similar properties.
The elements of the periodic table are grouped and organized together based on similar characteristics. These include their atomic number, chemical families (halides, noble gases, metals, gases, transition elements) and nuclear sizes, among other factors.
Because each atom in groups (or columns up and down) have similar chemical properties.
There is a line in the periodic table that separates the metals and the non-metals.
