Atoms are the smallest particle?
Protons + Neutrons Electrons Nucleus( Neutrons, Electrons, Nucleus ) = Nucleus (Atomic Mass Atomic Number Electrons( Atomic Mass, Atomic Number, Electrons ))
Protons are ____ charged...
Positively
Negatively
Electrons are ____ charged...
Protons = Atomic Number Atomic Mass Neutrons( Atomic Number, Atomic Mass, Neutrons )
Neutrons = Atomic Mass Atomic Number Protons( Atomic Mass, Atomic Number, Protons ) - Atomic Number Atomic Mass Electrons( Atomic Number, Atomic Mass, Electrons )
Thompson Discovered Atoms
Thompson made which model?
Plum Pudding Model
Nuclear Model
Electron Cloud Model
Rutherford found....
Atoms have a nucleus
Atoms are made up of mostly just space filled with electrons.
The Nucleus is made up of protons
Atoms are spheres
Alpha Particles are an atom that has lost resulting in it having a charge
Bohr suggest that Electrons can only appear in specific places corresponding to their energy levels
Chadwick identified that the nucleus atom protons( nucleus, atom, protons ) is made up of protons and neutrons which have mass but no charge weight taste( charge, weight, taste ).
In the periodic table Groups are..
Columns (Up and Down)
Rows (Left to Right)
In the periodic table Periods are..

Isotopes have the same number of protons neutrons electrons( protons, neutrons, electrons ) and electrons protons neutrons( electrons, protons, neutrons )
Iso = same element
Ions are atoms or groups of atoms that have lost or gained one or more ❌
When Ions lose electrons it means there are more protons, making the on charged.
When Ions gains electrons it means there are less protons, making the on charged
The first shell on an electron configuration can have ___ electrons
2
4
8
The second shell on an electron configuration can have ___ electrons
18
The third shell on an electron configuration can have ___ electrons
36
Acids have a pH scale from 0-7 7 7-14( 0-7, 7, 7-14 )
Bases have a pH scale from 7-14 7 0-7( 7-14, 7, 0-7 )
If the pH level is 7, it is neutral
A Lower pH level means...
Stronger Acid
Weaker Acid
Higher pH level means..
Stronger Base
Weaker Base
Acids have ❌ Ions
Base have ❌ ions
Characteristics of Acids Include:
Sour Taste
Turns Blue litmus paper red
Feels Slippery
Let's off heat
Characteristics of Bases can include:
Bitter Taste
Turns red litmus paper blue
Emits Light
