TRANSCRIPT

Page 1: Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group,

Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group, Row/Period

Page 2: Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group,

Negatively charged particles that surround the nucleus of the atom.

Page 3: Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group,

Equals the number of protons + neutrons in the atomic nucleus

Page 4: Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group,

Equals the number of protons (p+) in the nucleus

Each element has its own number of p+

Page 5: Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group,

These are located around the nucleus and are home to electrons.

Page 6: Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group,

An atom’s outer electrons

Page 7: Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group,

This model of the atom only shows the outer electrons

Page 8: Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group,

Is the average mass of all of the isotopes for a particular element

Is shown as a decimal

Page 9: Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group,

This model shows an atom’s protons, neutrons and electrons.

Page 10: Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group,

This number is positive if an atom loses electrons and negative if an atom gains electrons.

Page 11: Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group,

These are located horizontally in the PT

Page 12: Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group,

These are vertical columns in the PT

Page 13: Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group,

Different forms of the same element with the same # of p+ but different #s of no
