v152 NEXT — At-211 decay vs 1964 silver stable — 7.2h vs 62 years
At-211 BLACK HALOGEN DECAY:
- At-211 half-life 7.2h — decay modes: 41.8% α to Bi-207 + α 5.87 MeV -211mN -211mV — 58.2% EC to Po-211 — Po-211 half-life 0.516s α 7.45 MeV -268mN -268mV → Pb-207 stable — At-211 → Bi-207 32.9y → Pb-207 stable — At-211 → Po-211 0.516s → Pb-207 stable — final Pb-207 stable — Bi-207 also α? Actually Bi-207 EC β+? — Bi-207 32.9y EC → Pb-207 stable — so At-211 → Pb-207 stable via two paths — black halogen coin decays to lead + bismuth + α — 7.2h half-life — after 7.2h half gone, after 24h ~10% left, after 3 days ~1% left — At- black 2.27Å -211mV decays
- 0.07g At =2e20 atoms — initial activity A0=λN=2.67e-5×2e20=5.3e15 Bq =1.4e5 Ci — huge — after 7.2h half — after 1 day ~10% → 5e14 Bq — after 1 week ~0.01% → 5e11 Bq — decays quickly
1964 SILVER STABLE:
- 1964 90% Ag 10% Cu — Ag+ white 1.15Å + Cu+ orange 0.77Å — solid silver edge — stable isotope Ag-107 stable, Ag-109 stable — no decay — Cu-63 stable Cu-65 stable — 90% Ag 10% Cu stable forever — 1964→2026 62 years still 90% Ag — no half-life — Ag+ white stable — vs At- black decays 7.2h — 1964 silver stable vs black halogen decay — metal analogs ionic — Ag+ white stable vs At- black decays
CHAIN:
- At-211 7.2h: 41.8% α Bi-207 + α 5.87 MeV -211mN — Bi-207 32.9y EC → Pb-207 stable — 58.2% EC Po-211 0.516s α 7.45 MeV -268mN → Pb-207 stable — so At-211 → Pb-207 stable final — black halogen coin → lead + bismuth + α — vs silver stays silver
NEXT:
- 1964 silver stable 62 years — Ag+ white + Cu+ orange 90% Ag solid edge — still 90% Ag 2026 — melt value $21.45 $1 face
- Black halogen At- black 2.27Å -211mV decays 7.2h → Bi-207 + Po-211 → Pb-207 stable + α — black coin decays to lead — after 7.2h half black gone → Bi/Pb + α — after 1 week ~0% At- left → Pb/Bi + α — black halogen coin → lead coin — vs silver stays silver
Metal analogs ionic next:
- At- black anion 2.27Å -211mV -1 decays 7.2h → Bi3+? + α — Bi3+ 1.03Å brittle + α -211mN — Po2+ silvery 1.2Å +2 +268mN 0.516s → Pb2+ gray 1.19Å + α -268mN → Pb-207 stable gray — At- black → Pb gray — black → gray — decay
- Ag+ white 1.15Å + Cu+ orange 0.77Å 90% Ag stable forever — white + orange → white + orange forever — stable
So next = At-211 black halogen coin decays 7.2h → Bi-207 + Pb-207 + α vs 1964 silver stable 62 years Ag+ white + Cu+ orange stable — black decays, silver stable — metal analogs ionic — next please
