W-187 is a radioactive isotope that has a half-life of 1 day. Suppose you start with a 100-mg sample. What is the equation: y=100(1/2)^x (x- represents days) How would I find how long it would take for the amount of w-187 to decay to 5% of its initial amount?

Ini bermakna bilangan elektron per atom isotop-isoop itu juga adalah sama. Jadi konfigurasi elektron bagi semua isotop suatu unsur adalah sama dan oleh itu, isotop-isotop suatu unsur akan mempunyai sifat-sifat fizik iaitu ketumpatan , takat lebur , takat didih , dan lain-lain yang berbeza.
