Radioactive dating word problems

Orbiting around the nucleus are electrons (tiny particles each with a single electric charge).The atoms in each chemical element may vary slightly in the numbers of neutrons within their nuclei.Actually, it isn’t really a decay process in the normal sense of the word, like the decay of fruit.The daughter atoms are not lesser in quality than the parent atoms from which they were produced.Ages of many millions of years for rocks and fossils are glibly presented as fact in many textbooks, the popular media, and museums. One has only to wait: time itself performs the miracles.”1 Yet few people seem to know how these radiometric dating methods work.For decades, the biologists have boldly proclaimed that, whereas we cannot observe today one type of creature evolving into a totally different type of creature, “Time is the hero of the plot. No one even bothers to ask what assumptions drive the conclusions.This process of changing the isotope of one element (designated as the parent) into the isotope of another element (referred to as the daughter) is called radioactive decay.Thus, the parent isotopes that decay are called radioisotopes.

These parent radioisotopes change into daughter lead-206, lead-207, argon-40, strontium-87, and neodymium-143 isotopes, respectively.

Each atom is understood to be made up of three basic parts.

The nucleus contains protons (tiny particles each with a single positive electric charge) and neutrons (particles without any electric charge).

Some isotopes of some elements are radioactive; that is, they are unstable because their nuclei are too large.

To achieve stability, these atoms must make adjustments, particularly in their nuclei.

So, for example, every carbon atom contains six protons and six electrons, but the number of neutrons in each nucleus can be six, seven, or even eight.
