Elements in a family have similar chemical properties because they have same number of hype your answer. I

## Step 1<br />The problem is asking why elements in the same family (or group) on the periodic table have similar chemical properties. The periodic table is organized in such a way that elements with similar chemical properties are grouped together in the same column, or family.<br /><br />## Step 2<br />The reason for this similarity in chemical properties is that elements in the same family have the same number of valence electrons. Valence electrons are the electrons in the outermost shell of an atom and are involved in chemical reactions.<br /><br />## Step 3<br />The number of valence electrons determines how an element will react with other elements. Therefore, elements with the same number of valence electrons will have similar chemical properties.
