Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group, Row/Period
Negatively charged particles that surround the nucleus of the atom.
Equals the number of protons + neutrons in the atomic nucleus
Equals the number of protons (p+) in the nucleus
Each element has its own number of p+
C6 N7 O8 F9
These are located around the nucleus and are home to electrons.
An atom’s outer electrons
This model of the atom only shows the outer electrons
Is the average mass of all of the isotopes for a particular element
Is shown as a decimal
This model shows an atom’s protons, neutrons and electrons.
This number is positive if an atom loses electrons and negative if an atom gains electrons.
These are located horizontally in the PT
These are vertical columns in the PT
Different forms of the same element with the same # of p+ but different #s of no
