number of outermost electrons
Elements in the same column have similar chemical properties. They are from the same family.
Elements arranged in one column exhibit similar chemical properties. Elements in same column also have similar physical properties. Also elements in same column has similar electronic configuration.
Elements have more similar properties when they are found in the same column. Elements in the same column, also known as group or family, have similar chemical properties because they have the same number of valence electrons. Elements in the same row, also known as period, have different properties because they have different electron configurations.
The elements in same column have equal number of valence electrons. They have similar chemical properties.
Elements with similar properties are found in the same group or column on the periodic table. This is because they have the same number of valence electrons, which influences their chemical behavior. Elements in the same group tend to react in similar ways and have comparable physical properties.
These elements have more or less similar chemical properties.
Elements in a given column have the same number of valence electrons and hence the similar properties.
The electron configuration in the outer shell is the same for all of the elements in the same column. This results in some similar chemical properties between these elements in the same group (column).
In the Mendeleev periodic table, elements in each column had similar chemical properties because they shared the same valence electron configuration. This allowed for elements within the same group to exhibit similar reactivity and form similar compounds.
Elements in same column have equal number of valence electrons. so they possess similar chemical properties.
You can tell by the location, and the fact that they are both in the same column. Elements in the same column (or group) have similar properties.
the elements in a given column (or group) have the same number of valence electrons and hence similar chemical properties.
