Day unto day utters speech, and night unto night reveals knowledge.
There is no speech nor language where their voice is not heard.
Many geologists claim that radiometric “clocks” show rocks to be millions of years old.
However, to read any clock accurately we must know where the clock was set at the beginning.
If one of these protons is hit by a beta particle, it can be converted into a neutron.
With 18 protons and 22 neutrons, the atom has become Argon-40 (Ar-40), an inert gas.
Unlike our previous radioisotope clocks, which were based on a single parent-daughter decay sequence, the U-Pb and Th-Pb-based clocks involve multiple daughters in the decay chains, from of elements.
Elements in this series progressively fill the 5f electron orbitals and thus have similar electron configurations.Since the chemical properties of an element depend upon its electron structure, members of the actinide series have similar chemical properties.Potassium-Argon Dating Potassium-Argon dating is the only viable technique for dating very old archaeological materials.For every 100 K-40 atoms that decay, 11 become Ar-40.Cosmic rays enter the earth's atmosphere in large numbers every day. Terrestrial planets have hard surfaces that can be re-shaped by several different processes: impact cratering, volcanism, erosion, and tectonics.
