What’s that again?? VOCAB Review time!Atomic mass, mass number, atomic number, isotope, valence electrons, atomic charge, Bohr Model, Lewis Dot Model, electron, energy level, Family/Group, Row/Period What’s that again?? VOCAB Review time!
#1 Negatively charged particles that surround the nucleus of the atom.
#2 Equals the number of protons + neutrons in the atomic nucleus
C6 N7 O8 F9 #3 Equals the number of protons (p+) in the nucleusEach element has its own number of p+ C6 N7 O8 F9
#4 These are located around the nucleus and are home to electrons.
#5 An atom’s outer electrons
#6 This model of the atom only shows the outer electrons
#7 Is the average mass of all of the isotopes for a particular elementIs shown as a decimal
#8 This model shows an atom’s protons, neutrons and electrons.
#9 This number is positive if an atom loses electrons and negative if an atom gains electrons.
#10 These are located horizontally in the PT
#11 These are vertical columns in the PT
#12 Different forms of the same element with the same # of p+ but different #s of no Ex.
Atoms Chapter 2, Section 1.
All matter is made up of atoms
Bohr Model & Lewis Dot Diagrams
Valence Electrons & Bohr Diagrams
Inside an Atom. The Atom As A Model Structure of an Atom Atoms consist of protons, electron, and neutrons Atoms consist of protons, electron, and neutrons.
Structure of an Atom. What Is an Atom? An atom is often referred to as the building block of matter. Atoms have a nucleus surrounded by an electron cloud.
Atomic Mass & Number Isotopes The Periodic Table.
Properties of Atoms and the Periodic Table
ATOMIC STRUCTURE Inside the NUCLEUS ELECTRONS Subatomic PARTICLES Calculations Make it Stable! Periodic Table $100 $200 $300 $400 $500 $100 $200 $300.
Looking for Patterns in Chemical Reactivity. Elements and Compounds An element is a pure substance that cannon be broken down into simpler substances.
Periodic Table How to use it…. ATOMIC NUMBER: The number of protons in the nucleus. It is the number of protons that identifies the element
Introduction to Chemistry Bohr Models and Lewis Dot Structures

Atom Practical Review. Name the subatomic particles? Protons, Neutron, and Electrons.
