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 + C6N7O8F9C6N7O8F9
These are located around the nucleus and are home to electrons.
An atoms 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 atoms 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 n o Ex.

Bellringer Write down 5 things you know about atoms. Use chapter 4 if you need help remembering!
How to Draw Bohr Diagrams. 1)Find Carbon. 2)Determine the number of electrons – it is the same as the atomic number. 3)This is how many electrons you.
What is an atom? I love science, Ms. Solari! No, not this kind of Adam!
The Atom How big is an Atom? n The average size atom (Al) is about cm. n It would take a stack of 50,000 aluminum atoms to equal the thickness.
