zirconium, hafnium, and rutherfordium are all in the same family as titanium. To help you along your way, I'll let you in on a little secret:
An element's "family" is a fancy way of saying the "column" (vertical row) on the Periodic Table of elements. So anything in that column is in the same family as that element.
The reason it is organized this way is because all of the elements in that family have the same number of valance electrons (save for helium, which only has 2 valance electrons, and the rest of the noble gas family have 8). Valance electrons are the electrons in the outer most electron orbitals.
Uranium belongs to the actinide family of elements in the periodic table.
Zirconium is a transition metal, group 4 (titanium family: titanium, zirconium, hafnium, rutherfordium) and period 5 in the periodic table of Mendeleev.
Titanium is in period 4 and column 4 of a wide form periodic table. The elements most nearly similar to it chemically are zirconium and hafnium, the next heavier elements in the same column.
Heluim belongs to a group of elements called the noble gases
Tin belongs to the carbon family in the periodic table, also known as group 14. This family includes elements such as carbon, silicon, germanium, lead, and flerovium. All members of this family have four electrons in their outer energy level.
Titanium belongs to the family of transition metals.
Titanium belongs to same family as Hafnium. Both of them belongs to group-4.
Silicon belongs in the family of metalliods
Boron belongs to the family of elements known as metalloids or semimetals.
Chlorine belongs to the halogen family of elements.
Only Fluorine belongs in the halogen family.
Europium belongs to the lanthanide family, also known as the rare earth elements. These elements are found in the f-block of the periodic table and share similar chemical properties.
silicon belongs in the carbon family of the periodic table of elements
Uranium belongs to the actinide family of elements in the periodic table.
Holmium (Ho) is a member of the lanthanides family.
Zirconium is a transition metal, group 4 (titanium family: titanium, zirconium, hafnium, rutherfordium) and period 5 in the periodic table of Mendeleev.
It belongs to the Non-metals.
