Elements in the same GROUP will have similar. __ Atomic Numbers Chemical Properties Densities Energy Rings Rewatch

## Step 1<br />The problem is asking us to identify what elements in the same group of the periodic table have in common. The options provided are atomic numbers, chemical properties, densities, and energy rings.<br /><br />## Step 2<br />The atomic number of an element is unique to each element and does not change within a group. Therefore, atomic numbers are not a common characteristic of elements in the same group.<br /><br />## Step 3<br />Densities can vary greatly even within the same group. For example, the density of helium is much less than that of lead, even though both are in the same group.<br /><br />## Step 4<br />Energy rings are not a recognized term in chemistry, so this option can be disregarded.<br /><br />## Step 5<br />The chemical properties of elements in the same group are similar because they have the same number of valence electrons. This is the primary reason why elements in the same group exhibit similar chemical properties.
