- Beryllium is light, silver-gray, and relatively soft.
- Beryllium is strong but brittle.
- Beryllium is used as an alloy with copper to make spark-proof tools.
- Beryllium is used in radiation windows for x-ray tubes.
- Beryllium has the highest melting point of the light metals at 1278°C.
- Under normal conditions, a thin layer of the hard oxide BeO forms on beryllium's surface , protecting the metal from further attack by water and air.
What is radioactive decay?
an atomic nucleus emits an alpha particle and thereby transforms into atom with the mass number 4 less and the atomic number 2 less
a proton is transformed into a neutron, or vice versa, inside an atomic nucleus
the daughter nucleus that results is left in an excited state
