What four elements make up about 96% of the weight of the human body and what are their percentages?
Oxygen- 65% Hydrogen-10% Carbon 19% Nitrogen-3%
Explain the difference between the atomic number and atomic mass number of an atom.
Atomic number is the number of protons in the atom’s nucleus. Mass number is the sum of the protons and neutrons.
What is an isotope? What are radioisotopes and what are two uses of radioisotopes in medicine?
A variation of an element that has the same number of protons and electrons but a different amount of neutrons.
Isotopes that undergo radioactivity; unstable isotopes that decay.
Diagnose and treat cancer
How are ionic chemical bonds different from covalent chemical bonds?
An ionic bond gains or loses electrons.
A covalent bond shares electrons.
How are polar covalent bonds different form non polar covalent bonds?
Polar covalent bonds share electrons uniquely’ positive charge one end, other end negative
Non polar covalent bonds share electrons equally and have balanced charge.
What is an ion? How are cations different from anions? What is an electrolyte?
An ion is a charged particle.
Cations have a positive charge.
Anions have a negative charge.
Release ions in water and are electrically conductive in nature (treons)
Explain the difference between an anabolic and a catabolic chemical reaction and synthesis reaction.
Anabolic reactions form bonds.
Catabolic reactions break bonds
Synthesis reaction is when smaller bonds form to make larger bonds
Redox reactions involve both oxidation and reduction. Explain these two processes.
Electrons are exchanged; oxidized reactant is donor; reduced reactant is acceptor
Explain the difference between exergonic reactions and endergonic reactions.
Exergonic release energy and have less energy
Endergonic absorb energy and have more energy
List four factors that influence the rate of chemical reactions.
Temperature, concentration, particle size, and catalysts
