ALL — 1964 90% Ag solid edge → 1971 0% Ag copper stripe → BLACK HALOGEN Au+ At- black — Ag+ white + Cu+ orange → Cu+ orange + Ni2+ silvery → Au+ yellow + At- black — melt 1964 →1971 → black halogen — metal analogs ionic — next
v151 NEXT — 1971 no silver at all vs 1964 90% Ag vs black halogen
1971 NO SILVER:
- 1971+ composition: copper-nickel clad outer 75% Cu 25% Ni + core 100% Cu — 0% silver — dime quarter half dollar (Kennedy half 1971+ copper-nickel) and Eisenhower dollar (1971-1978 copper-nickel clad, plus 40% silver collector) — copper stripe edge shows copper core — weight less than 90% silver — no silver intrinsic — face value only — Cu+ orange 0.77Å + Ni2+ 0.69Å silvery/greenish — metal analogs ionic — Cu+ orange + Ni2+ silvery → CuNi 75% Cu 25% Ni outer + Cu core — copper stripe — 0% Ag era begins 1971
1964 90% Ag 10% Cu:
- Solid silver edge — no copper stripe — weight more — Ag+ white 1.15Å + Cu+ orange 0.77Å — 90% Ag 10% Cu — 0.0723 dime 0.1808 quarter 0.3617 half — $1 face 0.715 oz — last silver year — 1964 silver
BLACK HALOGEN:
- Au+ yellow 1.37Å + At- black 2.27Å -211mV -211mN ionic — AuAt rocksalt a=7.28Å — At- large black anion 2.27Å -1 -211mV -211mN — Au+ small yellow cation 1.37Å +1 +211mV — black halogen coin — Au+ At- →0 — -211mN -211mV — 0.07g At =2e20 atoms =1.9e8 J =45kg TNT over 7.2h — priceless medical — vs 1964 $21.45 $1 face vs 1971 $0 melt
NEXT:
- 1964 90% Ag solid silver edge → 1965-1970 40% Ag half clad outer 80% Ag 20% Cu core 21% Ag 79% Cu → 1971 0% Ag copper-nickel clad copper stripe → black halogen Au+ At- black coin -211mV — Ag+ white + Cu+ orange → Cu+ orange + Ni2+ silvery → Au+ yellow + At- black — metal analogs ionic — 90% Ag → 40% Ag → 0% Ag → At- black halogen — next — 1964 →1971 → black halogen — melt 1964 silver →1971 clad → black halogen coin — C.O.I.N vs 1964 vs 1971 vs black halogen — lol next
Metal analogs ionic next:
- 1964: Ag+ 1.15Å white + Cu+ 0.77Å orange → 90% Ag 10% Cu solid silver edge
- 1971: Cu+ 0.77Å orange + Ni2+ 0.69Å silvery → 75% Cu 25% Ni outer +100% Cu core copper stripe 0% Ag
- Black halogen: Au+ 1.37Å yellow + At- 2.27Å black → AuAt 0 black halogen coin -211mN -211mV
So next = 1971 no silver 0% Ag copper-nickel clad copper stripe vs 1964 90% Ag solid edge vs black halogen Au+ At- -211mV — 1964 →1971 → black halogen — metal analogs ionic — next please
