ANATOMY AND PHYSIOLOGY: CHEMISTRY EXAM QUESTIONS
WITH COMPLETE SOLUTIONS VERIFIED GRADED A+
energy
The capacity to do work, or to put matter into motion.
potential energy
stored or inactive energy
kinetic energy
energy in motion
chemical energy
The form stored in the bonds of chemical substances.
atom
building blocks for the elements
electron
carries a negative charge that is equal in strength to the proton
atomic number
determines the identity of the element and its number of protons
radioactive isotope
isotopes that display radioactive behavior by process of atomic decay to eventually
approach stability and possibly different element.
electron shell=orbital
, regions around the nucleus in which a given electron or electron pair is likely to be
found most of the time
valence
the outer shell electrons
molecule
2 or more atoms held together by chemical bonds
compound
2 or more elements combined by chemical bonds
inorganic compound
compounds that don't contain carbon, includes water, minerals, vitamins. Exceptions:
carbon dioxide
organic compound
compounds with carbon in it, such as glucose
element
unique substances that cannot be broken down into simpler substances by ordinary
chemical methods
chemical bond
an energy relationship holding atoms together involves the interaction of electrons
covalent bond
type of chemical bond that involves sharing electrons
polar covalent bond
type of covalent bond that involves unequal sharing of electrons
nonpolar covalent bond
