Family 14 elements are carbon - group elements. In Period 3, the element is Silicon ($\text{Si}$).

c. Period 1, Family 1

Period 1 has only two elements, and Family 1 (alkali metals) in Period 1 has Hydrogen ($\text{H}$) (note: some classification includes Hydrogen in Family 1, while others have a different view, but for this context, Hydrogen is the element here).

d. Period 2, Family 13

Family 13 elements are boron - group elements. In Period 2, the element is Boron ($\text{B}$).

e. Period 5, Family 9

Family 9 elements are transition metals. In Period 5, the element is Cobalt ($\text{Co}$)? No, wait, Period 5, Family 9: the element is Rhodium? No, wait, let's recall. The periodic table: Period 5, Family 9 (Group 9) element is Rhodium? Wait, no, Group 9, Period 5: the atomic number progression. Let's think again. Group 9: Fe (Period 4), Ru (Period 5), Os (Period 6), Ir (Period 7). So Period 5, Family 9 is Ruthenium? Wait, no, Group 9: the elements are Fe (26, Period 4), Ru (44, Period 5), Os (76, Period 6), Ir (77, Period 7). So yes, Ruthenium ($\text{Ru}$) is in Period 5, Family 9.

f. Period 4, Family 4

Family 4 (Group 4) elements. In Period 4, the element is Titanium ($\text{Ti}$).

g. Period 6, Family 18

Family 18 is noble gases. In Period 6, the noble gas is Radon ($\text{Rn}$).

h. Period 7, Family 1

Family 1 (alkali metals) in Period 7: the element is Francium ($\text{Fr}$) (but also, there are synthetic elements, but Francium is the natural one in Period 7, Family 1).

d. Family 5

Family 5 (Group 5) elements. An example is Nitrogen ($\text{N}$) (in Period 2, Family 15? Wait, no, Family 5 (Group 5) in modern numbering is Group 15? Wait, no, the old numbering: Family 5 was Group 5 (vanadium group). Wait, the question says "Family 5". If we consider the old IUPAC numbering (1 - 18, but some old systems had 1 - 8 for main groups and B groups for transition). Wait, maybe Family 5 (Group 5) in the old system: elements like Vanadium ($\text{V}$) (Period 4, Group 5). Or if it's Group 15 (pnictogens) as Family 5 in some systems, then Nitrogen ($\text{N}$). Let's assume Group 5 (transition metals): Vanadium ($\text{V}$).
