Atomic Structure

TermDefinition
Mass Number Protons + Neutrons
Atomic Number Protons
- 1 charge Electron
+ 1 charge Proton
Mass Number - Atomic Number Neutrons
Particles with significant mass Protons and Neutrons
Determines what element an atom is Protons
Exist in a "cloud" Electrons
Are found in the nucleus Protons and Neutrons
Changing these will only change the mass of the atom Neutrons
Changing these will change the charge of an atom Electrons
Changing these will change the type of atom Protons
This is how many electrons can fit on N = 1 2
Number of electrons that can fit on N = 2 8
Number of electrons that can fit on N = 3 18
Particles on the highest energy level valence electrons
Highest number of electrons in a valence shell 8
These match the number of protons in a neutral atom electrons
An atom with a charge (not neutral) ion
These are gained or lost to form an ion electrons
An atom that has gained electrons Anion
An atom that has lost electrons Cation
Compare these particles to discover the charge of an atom Protons and Electrons
Types of Pure substances Elements and Compounds
Elements in Group 1 Alkali Metals
Elements in Group 2 Alkaline Earth Metals
Elements in Group 3-12 Transition Metals
Elements in Group 17 Halogens
Elements in Group 18 Noble (or Inert) Gases
Elements on the left side of the Periodic Table (Most of the elements) Metals
Elements on the right side of the Periodic Table Nonmetals
Columns on the periodic table are called Groups
Rows on the periodic table are called Periods
You look at this on the periodic table to know how many energy levels an atom has Periods
You can look at this on the periodic table to quickly know how many valence electrons an atom has Groups
This is what determines the order of elements on the periodic table Atomic Number
2 or more elements chemically bonded together Compound
2 or elements physically put together Mixture
Water is classified as a ... Compound
Lead is classified as... Element
Air is classified as... Mixture
Homogeneous mixtures are usually Solutions
Elements are represented by... Symbol
Compounds are represented by... Formula
Elements here have 3 valence electrons Group 13
Elements here have a full valence Group 18
Elements here have 1 valence electron Group 1
Elements here want to gain 1 electron Group 17
Elements here want to lose 1 electron Group 1
Elements here want to lose 3 electrons Group 13
Brittle, often gas at room temperature, non-conductive Nonmetals
Shiny, malleable, conductive Metals
