APAKAH MAKSUD FERMIUM dalam CORSICA?
Fermium
Fermium adalah unsur sintetik dengan simbol Fm dan nombor atom 100. Ia adalah ahli siri actinide. Ia adalah elemen paling berat yang dapat dibentuk oleh pengeboman neutron unsur-unsur yang lebih ringan, dan oleh itu elemen terakhir yang boleh disediakan dalam kuantiti makroskopik, walaupun logam fermium tulen belum disediakan. Sebanyak 19 isotop diketahui, dengan 257Fm yang paling lama hidup dengan separuh hayat 100.5 hari. Ia ditemui dalam serpihan letupan bom hidrogen pertama pada tahun 1952, dan dinamakan sempena Enrico Fermi, salah satu pelopor fizik nuklear. Kimianya adalah tipikal untuk aktinida lewat, dengan keadaan pengoksidaan +3 lebih banyak tetapi juga keadaan pengoksidaan +2 yang boleh diakses. Disebabkan sejumlah kecil fermium yang dihasilkan dan semua isotopnya mempunyai separuh hayat yang pendek, kini tidak ada kegunaannya di luar penyelidikan saintifik asas.
