How does radioactive dating work
" Another way of explaining it is that when geologists talk about isotopes, they are talking about one element of differing masses.Isotopes of an element are atoms that all have the same atomic number (or number of protons in the nucleus) but have different atomic masses (hence different numbers of neutrons in the nucleus).The radioactive dating relies on spontaneous decomposition into other element. We know the rate at which things disintegrate at, so we can determine how much carbon is left and then apply a scientific formula and figure out how old the organism is. Radioactive dating refers to the process of measuring the age of an object using the amount of a given radioactive material it contains.The spontaneous decomposition is called radioactive decay. Relative dating, meanwhile, measures the order of past events, without determining their absolute age.
The atoms that are involved in radioactive decay are called isotopes.
This dating method can deliver results accurate to a million or two years in a billion years. Radioactive dating is also known as Radiometric dating.
"Radiometric dating - the process of determining the age of rocks from the decay of their radioactive elements" Wiens, RC 2002, Radiometric Dating A Christian Perspective, 'Science in Christian Perspective', The American Science Affiliation, viewed 8 September 2009, Carbon dating is one type of radiometric dating, there are others.
In reality, every atom is an isotope of one element or another.
However, we generally refer to isotopes of a particular element (e.g., Rubidium-87 (Pb)).
And once that first kernel pops, it will never be a kernel again..is forever changed! ) Teaching example using popcorn to teach radioactive decay "A variety of a chemical element (strictly, of one particular element) which is distinguished from the other varieties of the element by a different mass number but shares the same atomic number and chemical properties (and so occupies the same position in the periodic table)." That definition may not mean anything to them.
