BIO 102 TEST 1 WITH ALL CORRECT &
VERIFIED ANSWERS (UPDATED TO PASS)
Chemistry Correct answer-the study of matter and energy
Matter Correct answer-anything that has mass(weight) and takes up space
Elements Correct answer-cannot be broken down to a simpler form (periodic table lists all)
Atom Correct answer-smallest functional unit of elements
ATOM: Nucleus Correct answer-central core
ATOM:NUCLEUS: Protons Correct answer-positive charge, have mass
in electonically neutral atom it = # of electrons
ATOM:NUCLEUS: Neutrons Correct answer-0 charge, have mass
atomic # - mass # = # of neutrons
ATOM: Shells Correct answer-surrounding nucleus (an atom fills up from the inside out)
1st Shell = 2 electrons
2nd Shell = 8 electrons
3rd Shell = 18 electrons
(in order for an atom to be satisfied it has to have the max amount of electrons for that shell/or 8)
- most stable when outermost shell is full
- will interact with other atoms to fill outermost shells
ATOM:SHELLS: Electrons Correct answer-negative charge, no discernible mass
in electonically neutral atom it = # of protons
atomic symbol Correct answer-1 or 2 letters
Ex. Na= Sodium, O= Oxygen
atomic number Correct answer-number of protons
(number of electrons b4 chemical reaction)
atomic mass Correct answer-roughly equal to the number of protons plus neutrons
protons+neutrons=atomic mass
isotopes Correct answer-have different number of neutrons
same atomic number and number of protons
but different atomic mass (# of neutrons)
radioisotopes Correct answer-unstable isotopes that give off energy/particles/energy in form of
radiation
some have scientific/medical uses
ex. Carbon 14(dating fossils), cancer treatment, power supply for pacemakers
energy Correct answer-capacity to do work
potential energy Correct answer-stored energy (can be transformed into kinetic)
