A & P: CHAPTER 2 STUDY GUIDE WITH ALL
CORRECT & VERIFIED ANSWERS
CHAPTER 2
STUVIA2024 5/24/25 ANATOMY & PHYSIOLOGY
, Atom Correct answer-the smallest unit of an element that still retains is physical properties of the
element
Element Correct answer-All matter is composed of this basic substance
Subatomic particles in nucleus Correct answer-protons & neutrons
Electrons Correct answer-orbit the nucleus in the shells
Protons Correct answer-carry a positive charge
Electrons Correct answer-carry a negative charge
Mole Correct answer-6.02 x 10^23, also called Avogardro's number, is the number of carbon atoms
in exactly 12 grams of carbon 12
Isotopes Correct answer-atoms of the same element that have different numbers of neutrons
Radioactive Isotopes Correct answer-an element that decays, or gives off some type of energy
Tracer Correct answer-A small amount of radioactive isotope, used to detect molecular changes
Molecules Correct answer-Atoms bond to each other to form a chemical unit
Compound Correct answer-When the atoms are different
Ionic bond Correct answer-created by electrical attraction
Covalent bond Correct answer-created by sharing of electrons between atoms
Ions Correct answer-particles that carry either positive or negative charges
Ionic Lattice Correct answer-dissociates
Hypertension Correct answer-High blood pressure
Rickets Correct answer-bowing of legs due to not enough calcium
Arrhythmia Correct answer-irregular heartbeat due to too much or too little potassium
Electronegative Correct answer-"electron grabbing", an element that keeps the electrons for a
longer period of time
Polar Covalent Bond Correct answer-most of the electrons spend most of their time with the
electronegative element
Non-Polarcovalent Bond Correct answer-Molecules linked by this type of bond do not have an
electrical charge
Inorganic molecules Correct answer-they do not have carbon
