⫸ How many naturally occurring elements are there? Answer: 91
naturally occurring elements.
⫸ Which six elements make up 98.5% of body weight? Answer:
Oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
⫸ What are trace elements and their significance? Answer: Trace
elements are present in minute amounts but play vital roles, making up
about 4% of body weight, mostly calcium and phosphorus.
⫸ What is the role of minerals in the human body? Answer: Minerals
are inorganic elements extracted from soil by plants and passed up the
food chain, contributing to body structure and enzyme function.
⫸ What defines isotopes of an element? Answer: Isotopes are varieties
of an element that differ only in the number of neutrons and therefore in
atomic mass.
,⫸ How do isotopes of an element behave chemically? Answer: Isotopes
of an element have identical chemical behavior due to the same number
of valence electrons.
⫸ What is a radioisotope? Answer: An unstable isotope that decays and
gives off radiation in a process called radioactivity.
⫸ What is ionizing radiation? Answer: Radiation that can eject
electrons, destroy molecules, create free radicals, and potentially cause
genetic mutations and cancer.
⫸ What is the physical half-life of a radioisotope? Answer: The time
required for 50% of the radioisotope to decay to a stable state.
⫸ What is the biological half-life of a radioisotope? Answer: The time
required for 50% of the radioisotope to disappear from the body.
⫸ What is an ion? Answer: A charged particle (atom or molecule) with
an unequal number of protons and electrons.
⫸ What is ionization? Answer: The transfer of electrons from one atom
to another.
⫸ What is an anion? Answer: A particle that has a net negative charge
due to the gain of electrons.
,⫸ What is a cation? Answer: A particle that has a net positive charge
due to the loss of electrons.
⫸ What happens to ions with opposite charges? Answer: They are
attracted to each other.
⫸ What is the significance of isotopes in terms of atomic weight?
Answer: Atomic weight accounts for the fact that an element is a
mixture of isotopes.
⫸ How do isotopes differ in physical behavior? Answer: Isotopes can
differ in their physical behavior despite having identical chemical
behavior.
⫸ What are some examples of ionizing radiation? Answer: UV
radiation, X-rays, alpha particles, beta particles, and gamma rays.
⫸ What is the relationship between isotopes and atomic weight?
Answer: Extra neutrons in isotopes increase atomic weight.
⫸ What is the role of free radicals in the body? Answer: Free radicals
can cause damage to cells and contribute to genetic mutations.
, ⫸ What are salts in the context of ions and electrolytes? Answer: Salts
are electrically neutral compounds of cations and anions that readily
dissociate in water into ions and act as electrolytes.
⫸ What are electrolytes? Answer: Electrolytes are substances that
ionize in water and form solutions capable of conducting electric
current.
⫸ What are the functions of electrolytes? Answer: Electrolytes are
involved in chemical reactivity, osmotic effects, and the electrical
excitability of nerve and muscle.
⫸ Why is electrolyte balance important in patient care? Answer:
Electrolyte imbalances can lead to serious health issues such as coma or
cardiac arrest.
⫸ What are free radicals? Answer: Free radicals are unstable, highly
reactive particles with an unusual number of electrons, produced by
normal metabolic reactions, radiation, and certain chemicals.
⫸ What are the potential dangers of free radicals? Answer: Free radicals
can trigger reactions that destroy molecules, potentially causing cancer,
death of heart tissue, and aging.
⫸ What is an example of a free radical? Answer: An example of a free
radical is the superoxide anion.
