NAME AND DESCRIBE THE SUBATOMIC PARTICLES THAT MAKE UP AN ATOM.
NAME AND DESCRIBE THE SUBATOMIC PARTICLES THAT MAKE UP AN ATOM.
PROTON – 1 amu, +1 CHARGE, FOUND IN THE NUCLEUS
NEUTRON – 1 amu, 0 CHARGE, FOUND IN NUCLEUS
ELECTRON – 0 amu, -1 CHARGE, FOUND IN ORBITS AROUND THE NUCLEUS
WHAT IS ATOMIC NUMBER, Z?
WHAT IS ATOMIC NUMBER, Z?
Z = # PROTONS IN A NEUTRAL ATOM, IT IS ALSO EQUAL TO THE # ELECTRONS
WHAT IS ATOMIC MASS?
WHAT IS ATOMIC MASS?
A = ATOMIC MASS = # PROTONS + # NEUTRONS
WHERE IS MOST OF THE MASS OF AN ATOM LOCATED?
WHERE IS MOST OF THE MASS OF AN ATOM LOCATED?
IN THE NUCLEUS
WHAT DETERMINES THE CHEMICAL PROPERTIES OF AN ELEMENT?
WHAT DETERMINES THE CHEMICAL PROPERTIES OF AN ELEMENT?
THE ATOMIC NUMBER, WHICH IS ALSO EQUAL TO THE NUMBER OF ELECTRONS.
THE DENSITY OF ALUMNUM IS 2.70 g/ml. A PIECE OF ALUMNUM FOIL HAS A VOLUME OF 54 ml. WHAT IS THE MASS OF THIS PIECE OF ALUMINUM FOIL?
A. 145.8 gB. 20 gC. 14.58 gD. 0.05 g

A. 145.8 gB. 20 gC. 14.58 gD. 0.05 g
WHICH OF THE FOLLOWING IS AN EXAMPLE OF A PHYSICAL CHANGE?
A. formation of silver sulfide when silver reacts with sulfur in the air
B. burning of methane gas, which produces water and
carbon dioxide.C. condensation of water vapor on
the outside of a cold can of sodad. vinegar and baking soda,
combining and forming a salt and water.

HOW DO ISOTOPES OF THE SAME ELEMENT DIFFER?
A. THEY HAVE THE SAME NUMBER OF PROTONS AND ELECTRONS, BUT A DIFFERENT NUMBER OF NEUTRONS
B. THEY HAVE THE SAME NUMBER OF PROTONS AND
NEUTRONS, BUT A DIFFERENT # OF ELECTRONS
C. THEY HAVE THE SAME NUMBER OF NEUTRONS AND
ELECTRONS BUT A DIFFERENT NUMBER OF PROTONS
D. THEY HAVE DIFFERENT SYMBOLS

WHAT IS SCIENCE?
WHAT IS SCIENCE?
A SYSTEMATIC STUDY OF HOW THINGS HAPPEN.
WHAT IS CHEMISTRY?
WHAT IS CHEMISTRY?
THE SCIENCE OF MATTER AND ITS INTERACTIONS.
WHAT IS PHYSICS?
WHAT IS PHYSICS?
THE SCIENCE OF ENERGY
WHAT IS LIGHT?
WHAT IS LIGHT?
A FORM OF ENERGY WITH BOTH WAVE AND PARTICLE PROPERTIES.
HOW ARE TWO WAYS THAT YOU COULD CHARACTERIZE LIGHT?
HOW ARE TWO WAYS THAT YOU COULD CHARACTERIZE LIGHT?
WAVELENGTH
FREQUENCY
AT WHAT WAVELENGTHS DOES VISIBLE LIGHT EXIST?
AT WHAT WAVELENGTHS DOES VISIBLE LIGHT EXIST?
400 TO 700 nm
HOW DOES THE ENERGY PER PHOTON CHANGE WITH INCREASE IN WAVELENGTH?
HOW DOES THE ENERGY PER PHOTON CHANGE WITH INCREASE IN WAVELENGTH?
ENERGY DECREASES
WHAT KIND OF SPECTRA DOES A HEATED SOLID EMIT?
WHAT KIND OF SPECTRA DOES A HEATED SOLID EMIT?
CONTINUOUS OR BAND SPECTRA
WHY?
WHAT KIND OF SPECTRA DOES A HEATED SOLID EMIT?
CONTINUOUS OR BAND SPECTRA
WHY?
THE ATOMS ARE PACKED CLOSE TOGETHER, AND THE ELECTRONS INTERFER WITH EACH OTHER.
WHAT KIND OF SPECTRA DOES A HEATED GAS EMIT?
WHAT KIND OF SPECTRA DOES A HEATED GAS EMIT?
LINE SPECTRA
WHY?
WHAT KIND OF SPECTRA DOES A HEATED GAS EMIT?
LINE SPECTRA
WHY?
THE ATOMS ARE FAR APART, AND THE ELECTRONS ON ONE ATOM CAN ACT INDEPENDENTLY FROM THOSE ON ANOTHER.
AS THE TEMPERATURE OF A SOLID INCREASES, HOW DOES THE lmax (wavelength of maximum light intensity) CHANGE?
AS THE TEMPERATURE OF A SOLID INCREASES, HOW DOES THE lmax (wavelength of maximum light intensity) CHANGE?
IT IS SHIFTED TO SHORTER WAVELENGTHS.
WHAT IS THE DOPPLER EFFECT?
WHAT IS THE DOPPLER EFFECT?
HOW WAVELENGTH CHANGES WHEN AN EMITTING OBJECT IS MOVING RELATIVE TO YOU

WHAT DOES TEMPERATURE MEASURE?
WHAT DOES TEMPERATURE MEASURE?
THE AVERAGE KINETIC ENERGY OF THE PARTICLES IN THE OBJECT.
