Why are these elements in the same column in the periodic table?

Why are these elements in the same column in the periodic table?

The vertical columns (groups) of the periodic table are arranged such that all its elements have the same number of valence electrons. All elements within a certain group thus share similar properties.

Why is it that the elements in the same column in the periodic table have similar chemical and physical properties?

Elements in the same column of the Periodic Table have the same number of valence electrons – that’s why they have similar chemical properties.

What do elements in the same column on the periodic table have in common?

Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.

Why do elements in the same column have the same number of valence electrons?

The elements in the same group has similar number of valence electrons. They have identical number of electrons in their outermost shell. e.g. All the alkali metals in Group 1 have 1 valence electron, so they all tend to react the same way with other substances.

Do elements in the same column of the periodic table exhibit the same physical properties?

In chemistry, a group is a vertical column in the periodic table of the chemical elements. Each element within a group has similar physical or chemical properties because of its atom’s outermost electron shell (most chemical properties are dominated by the orbital location of the outermost electron).

What do elements in the same group have in common What do elements in the same period have in common?

Elements in the same period are those that are in a single horizontal line from left to right. They do not share the same type of chemical reactivity as seen in groups. They only real thing that these elements share in common is the same principal quantum number, or main energy shell.
