Hf-176

In the land of hafnium, so rare and bright, There are isotopes that shine with all their might. Five stable ones, they never decay, 176, 177, 178, 179, and 180, hooray! But there's one radioisotope, so very old, 174 Hf, its story must be told. With a half-life so long, it's hard to believe, 7.0×10^16 years, it's hard to conceive! Now let's talk about the synthetic kind, Radioisotopes that scientists find. Thirty-four in total, they're quite a sight, The most stable one is 182 Hf, shining so bright! Hafnium-tungsten dating, a scientific quest, Using 182 Hf to study what's best. To understand the chronology of our Earth, And how planets formed, their incredible birth. And let's not forget the nuclear isomers, Twenty-seven in total, they're quite the performers. The most stable of all is 178m2 Hf, With a half-life of 31 years, oh what a relief! So let's explore the world of hafnium, With its isotopes so fascinating and fun. From stable to radioactive, they all play a role, In unraveling the mysteries of our cosmic soul. Random page: Fr.
