Methods

¿WHAT ARE THE METHODS THAT THE SCIENTIST USE TO DETERMINE DE AGE OF REMAINS FOUND FORM THE PAST? METHODS:

. Radioactive decay: it gives when certain atoms are unstable, and their nucleus separate in parts changing in other elements. Some of these radioactive elements become to themselves when emitting a particle of high energy, this process is called “alpha decay”. Other radioactive elements decay when a neutron breaks, producing a proton and an electron, to this process is called to him “beta decay ".

.Carbon14 Also the age of the elements can be determined by means of carbon14. It is used to determine the age of some things: bones, wood, vegetal fibers, that were created in a relatively recent past by human activities. The Carbon 14 is radioactive, being his “period” of 5730 years (that is, at the 5730 years of the death of an alive being, the amount of C14 in his fossil rest is reduced to half).
