22 City Trees T hroughout most of New York State, maple species are the most common street tree. It is not unusual for Norway ( Acer platanoides ), silver ( A. saccharinum ), sugar ( A. saccharum ), red ( A. rubrum ), and other maples species to comprise over 50% of the street tree population in ...

Nuclear Energy: Nuclear Decay

Nuclear Energy: Nuclear Decay Introduction The Nucleus Almost any phrase that has the word "nuclear" in it has a bad reputation. The term conjures up images of mushroom clouds and radioactive mutants.

Nuclear Decay

Name Date Class 1 of 3 MATH SKILLS Nuclear Decay Polonium is the scarcest natural element and was the first to be discovered by the Curies. Write the equation for the alpha decay of polonium-210, and determine what isotope is formed by the reaction.
