is it at every tenth element
The elements with similar properties are placed in groups. Periodic table contain 18 groups.
lanthanum and other lanthanides
Fluorine, at the top of the periodic table column that includes bromine.
By looking down its column called a group
Groups on the periodic table with similar properties are called families.
The element in a given vertical column (or groups) have the same number of valence electrons and hence have similar properties.
Beryllium (Be). This is because on the periodic table Be is located in the same group (column) as Calcium and is the highest element in that column. Elements of the same group have similar properties and their masses decrease the higher they are in the group.
The two elements that have the most similar chemical properties to arsenic are Phosphorus (P) and Antimony (Sb).
