Answer to Question 1

A radioactive isotope is one that undergoes spontaneous decay from one isotope of an element to
another isotope of that same element, or even change to other elements. Radioactive isotopes are
important for determining the absolute ages of rocks.



Answer to Question 2

Two or more atoms join together by bonding, resulting in a substance called a compound. The most
common types of bonding are ionic and covalent. The less common types are metallic and van der
Waals.
