case typical iron-56 becomes iron-57‚ 58 and then 59. The heavy iron-59 atom is very unstable and decays to cobalt-59. Then cobalt-59 captures a neutron and becomes cobalt-60‚ which is very unstable and decays into nickel 60. c) How does the radioisotope decay and state its half-life. Cobalt-60 undergoes radioactive decay with the emission of beta particles and strong gamma radiation. It ultimately decays to non-radioactive nickel with a half-life of 5.24 years. d) Identify those properties of the

Meth Mouth Meth mouth is severe decay and loss of your teeth. Tooth fractures and acid erosion can also occur. Meth mouth occurs when someone has had an extended period of time using methamphetamine. Meth mouth is caused by the side effects of the drug and also lifestyle choices. Side effects of meth include clenching‚ grinding the teeth‚ and dry mouth. If someone who uses meth has poor oral hygiene and drinks a lot of sugary drinks‚ their teeth are usually worse than meth users who have good

It was used to describe a period with many social problems that were masked by the rise of new money. Greed‚ scandal‚ and corrupt policies ran rampant during this time; however‚ as we look back‚ this was also a point in history where

First‚ one of the reasons that led to the decline of the Western Roman Empire was cause by inside decay. It has been said that the Roman’s military crisis was a huge factor in this decay.
