What Is The Main Cause Of Isotopes? Answer: Explanation:Now the reason for existence of isotopes can be explained by unstability of elements. Some elements are unstable so they emit neutrons in form of some radiation e.g. 14C and 13C are unstable and so they continuously emits neutrons in the form of radiation. What are the
Is It True That Some Elements Can Decay Over Time? Yes, the decay half-life of a radioactive material can be changed. Radioactive decay happens when an unstable atomic nucleus spontaneously changes to a lower-energy state and spits out a bit of radiation. This process changes the atom to a different element or a different isotope.
What Are The Characteristics Of Radioactive Decay? Radioactive decay is the process by which an atomic nucleus undergoes a spontaneous change, emitting an alpha particle or beta particle and/or a gamma ray . Radioactive decay is a natural process that takes place in the air, water, and soil at all times. What are the 3
Is Radioactive Decay Affected By Pressure? As radioactive decay is a nuclear process it is considered to be insensitive to external factors such as pressure or chemical environment. Is radioactivity affected by temperature or pressure? Temperatures do not affect radioactivity at all. This has been tested many times and at extreme temperatures. Temperature is the
How Do You Compare Two Isotopes? all isotopes have the same number of protons and the same number of electrons. Because the electron structure is the same isotopes have the same chemical properties. What is different is the number of neutrons, The different number of neutrons all cause a difference in the atomic weight or
How Can Carbon 14 Be Used To Determine The Age Of Fossils? Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food. … Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can
How Can Carbon 14 Be Used To Determine Age? Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food. … Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by
How Do You Know If An Ion Is Stable? The octet rule What is a stable ion? Atoms are at their most stable when their outermost energy level is either empty of electrons or filled with electrons. Ions. Sodium atoms have 11 electrons. Two of these are in the lowest energy level, eight are in
Which Elements Have Isotopes With The Same Number Of Protons And Neutrons? Chemical Symbol Name PbLeadPlumbum Do isotopes have the same number of neutrons and electrons? Basic principles. Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of
How Do Scientists Use Radioactive Dating To Determine The Age Of A Fossil? To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and
