life and physical science
Physical properties of matter can be observed or measured
Examples
Density
mass divided by volume
m/v
mass
measures amount of a substance is in an object
Everything that contains atoms has mass
Kilogram(kg) used for Macroscopic objects (rock, glass of water, balloon full of helium)
Atomically speaking masses= small
Neutron = greater mass than proton
atoms atomic mass is approximately the sum of the masses of the protons and neutrons contained in the atoms nucleus
proton= slightly less than neutron
Electron= so small can be approximated as 0
unit of mass at the atomic level =AMU= atomic mass unit
Atomic weight = molecular weight=atomic mass= molecular mass
Example: atom with an atomic mass of 10 AMU= atomic weight of 10 grams
atomic weight = average mass of an atom of an element
essential property of matter that is determined by the type and number of atoms that compromise a given sample of matter
Volume
All matter has volume
the amount of space that a sample occupies
Weight
force that acts on matter in a gravitational field
Temperature
Basic atomic structure
Protons
atomic number = # of protons
neuturons
electrons
atomic nucleus
protons+ neutrons= nucleons
atomic mass
number of protons + neutrons
periodic table
rows =periods
columns=groups
