In the same column.
A scientist can find an element with properties similar to another by looking at elements in the same group or column of the periodic table. Elements in the same group tend to have similar chemical properties due to their similar outer electron configurations. This allows scientists to predict the behavior of an element based on its position on the periodic table.
Praseodymium (Pr) is an element in the periodic table that has properties most similar to cerium (Ce). Both elements are lanthanides and share similar chemical properties, including their reactivity and oxidation states.

Elements present within a same group normally have similar properties
A scientist can find an element with similar properties by locating the element of interest on the periodic table and examining the elements in the same group (column). Elements within the same group have similar chemical properties due to having the same number of valence electrons. Additionally, the periodic trend of properties such as electronegativity, atomic radius, and ionization energy can provide insights into the similarities among elements in adjacent groups or periods.
is it at every tenth element
You would see which group the element was in and then replace it with another element from the same group, as all elements in a group have similar properties. For example you could replace Sodium with Potassium as they are both in Group 1.
Selenium has similar properties to sulfur as they are both in the same group on the periodic table (Group 16) and share similar chemical reactivity and properties.
To find an element that is similar to another element, look in the periodic table and find an element in the same column (group/family) as the element of interest. Usually, elements within the same group/family have very similar properties.
The element that would have properties most similar to the new element would be an element that lies in the same group as the new element. Specifically, the element with the most similar properties will lie directly above or below that element in the group.
lanthanum and other lanthanides
In the columns of the periodic table, chemical properties are similar.
