You are watching: How many valence electrons does radium have
How was it discovered?Marie Curie and also her husband Pierre found the facet while trying out with the mineral dubbed pitchblende in 1898. It took one more 12 years for Marie Curie to ultimately isolate metallic radium in 1910.Where did radium get its name?The name comes from the Latin native "radius" which means ray. They named it after ~ the rays the were emitted indigenous the element.IsotopesThere are 4 naturally emerging isotopes of radium. The many abundant is radium-226 which has actually a half-life that 1600 years. None of the isotopes room stable. They are all produced by the decay of the elements uranium and thorium.Interesting Facts about RadiumThe element "curium" is named for the discoverers of radium.Marie Curie likewise discovered the element polonium while exploring with pitchblende.Before the threats of radiation to be understood, radium was referred to as the wonder metal since it gave off heat and light.Radium is component of a degeneration chain wherein it will slowly decay into radon, climate polonium, and finally lead.The unit for measuring radioactivity is referred to as the "curie" after scientists Marie and Pierre Curie.
