# Find the Missing Members of this Family

Who are the Missing Members?

$$?$$, $$V$$, $$U$$, $$?$$, $$S$$, $$?$$, $$P$$, $$O$$, $$N$$, $$?$$, $$H$$, $$F$$, $$?$$, $$B$$

The missing members are:

Y, W, K, I, C

Making the full sequence:

Y, V, U, W, S, K, P, O, N, I, H, F, C, B

Because these are:

The one-letter chemical element abbreviations from the Periodic Table, when the full names are arranged in reverse alphabetical order: Yttrium (Y), Vanadium (V), Uranium (U), Tungsten (W), Sulfur (S), Potassium (K), Phosphorus (P), Oxygen (O), Nitrogen (N), Iodine (I), Hydrogen (H), Fluorine (F), Carbon (C), Boron (B).

• Congrats!...must be good in chemistry – Uvc Jun 18 '19 at 21:51
• One of my faves! Far better than at formatting my answers...! – Stiv Jun 18 '19 at 21:52
• (Not knocking your answer but why is your 2nd letter 4th overall and not 2nd overall @Uvc ?) – El-Guest Jun 18 '19 at 22:04
• @El-Guest Because the order is based on the full name of the element rather than just the symbol :) Translate the W as 'Tungsten' and it slots in 4th in the sequence, behind Yttrium, Vanadium and Uranium. – Stiv Jun 18 '19 at 22:08
