You can derive the valency of many elements by looking at their positions in the periodic table, but this isn't true for all of them. It's also possible to calculate the valency of an atom or molecule by noting how it combines with other atoms or molecules with known valencies. Also using octet rule , periodic table and chemical formula etc..we can get valency of ions
