VISUAL ANATOMY AND PHYSIOLOGY
CHAPTER 27 FINAL PAPER SOLVED QUESTIONS
WITH COMPLETE ANSWERS
◉ inert elements.
Answer: atoms that have filled outermost energy levels
◉ ion.
Answer: atoms that have gained or lost electrons
◉ cation.
Answer: positive ion
◉ anion.
Answer: negative ion
◉ ionic bond.
Answer: type of chemical bond created by the electrical attraction
between cations and anions; example is NaCL (salt)
◉ nonpolar molecules.
,Answer: electrically balanced molecules; do not have oppositely
charged ends; atoms share their electrons equally.
◉ covalent bond.
Answer: type of chemical bond created by atoms sharing electrons
in their outermost energy levels; example is H2O (water)
◉ polar molecules.
Answer: molecules that have an unequal distribution of charges;
forms when atoms have unequal pulls on electrons they share;
example is water
◉ molecule.
Answer: chemical substance made up of atoms of one or more
elements that are held together by covalent or ionic bonds
◉ molecular weight.
Answer: sum of atomic weights of component atoms in a molecule
◉ mole.
Answer: a quantity with a weight in grams equal to the substance's
atomic or molecular weight; one mole of a particular element or
molecule always contains the same number of atoms or molecules as
one mole of another element; atomic weight of oxygen is 16, so 1
, mole of oxygen atoms equals 8 grams; atomic weight of hydrogen is
1, so 1 mole of hydrogen atoms equals 1 gram
◉ chemical reactions.
Answer: process in which chemical bonds are broken or formed
between atoms in reactants to form different substances (products)
◉ metabolism.
Answer: all of the chemical reactions occurring in the body at a given
time
◉ work.
Answer: movement of matter or change in the physical structure of
matter
◉ energy.
Answer: the capacity to perform work
◉ kinetic energy.
Answer: energy of motion
◉ potential energy.
Answer: stored energy
