Solution. 18.0g ⇒ 9.0g ⇒ 4.5g ⇒ 2.25g, this is three half-lives \[ \text{how old (time)} = 3 \times 1600\, years onumber\] This decay process takes 4800 years to occur. Thirty-four isotopes of radium, all radioactive, are known; their half-lives, except for radium-226 (1,600 years) and radium-228 (5.75 years), are less than a few weeks.
