500. Correct Answers 3 significant figures
7A Correct Answers Halogens
8A Correct Answers noblle gases
A measure number Correct Answers consists of
certain digits and an estimated digit. Last number
in a measurement is estimated.
Acids Correct Answers sour taste
turn blue litmus red
neutralizes bases
Atmospheric pressure Correct Answers pressure
exerted by a column of air from the top of the
atmosphere to the surface of the earth
,Atomic mass Correct Answers mass of a single
atom in atomic mass unit
Atomic mass number Correct Answers weighted
average of masses of all isotopes based on their
fractional natural abundances
not the same as mass number, which is always a
whole number
Atomic mass unit (amu) Correct Answers chemists
use this to give masses of atoms and subatomic
particles
Atomic Number Correct Answers Atomic number
= number of protons = number of electrons
Atomic radius Correct Answers from left to right,
decreases
going down, it increases
Atomic spectrum Correct Answers consists of lines
of different color (line spectrum), formed when
light from a heated element passes through a
