The Structure Of the atom
+1 Charge, Nucleus, Mass 1 AMU
Protons
True Or False, 2 Elements Can Have The Same Atomic Number
False
What Are The 3 Major Groups On The Periodic Table
Metals, Nonmetals, Metalloids
Periodic Table of
Elements
A covalent bond occurs when atoms share electrons between them
True or False, Protons= Atomic Number
True
Number Of Neutrons+Number Of Protons=
Mass Number
Physical Properties To Distinguish Between The 3 Groups are
Luster(Ability Of A Substance To Reflect Light), Conductivity (The Ability Of The Substance To Conduct Electricity), Malleability (The Ability Of The Substance To Be Hammered Into Sheets Without Breaking), And Ductility (The Ability Of The Substance To Be Pulled Into A Thin Wire)

What is a Ionic Bond
an ionic bond forms when one atom completely transfers electrons to another
Neutrons are....
Mass 1 Amu, Nucleus, No Charge
Number Of Neutrons Is Found By
Mass Number-Atomic Number
Found left of the zigzag line on the periodic table, solid at room temp (except for mercury), good conductors of electricity and heat
Metals
How many Columns are on the periodic table
18
what bond forms when Electrons are shared (nonmetals)
Covalent Bonds
Negative Charge, Orbits Nucleus, Virtually No Mass
Electrons
What Are Isotopes
An Atom With The Same Number Of Protons, But Different Number Of Neutrons
Nonmetals are
Found to the right of the zigzag line on the periodic table, solid, liquid, or gas at room temp., poor conductors of electricity and heat, not metallic looking
How many groups are in the periodic table (not metals, nonmetals, and metalloids)
9 groups
Ionic Bonds are formed when
Positive(+) and negative(-) combine
Have The Same Number Of Protons And Electrons, No Overall Charge, As written on periodic table, All Atoms Are Neutral
Neutral Atoms
Ions Are
Metalloids are (semi-conductors)
How many elements on the periodic table are man-made
24 elements
How many valence electrons do chemical bonds need to become stable
