what did Democritus the greek pholosipher find out 2000 years ago
discovered nucleus and protons
all matter is made up of tiny particles
projected atoms through a glass tube
gold foil experiment
what did John Dolton find out in the 1880's-1890's
electrons aren't fixed on a energy level
all matter is made up of tiny particles
all matter is made of atoms which are invisible and all atoms of the same substances are identical
projected atoms through a glass tube
what did J.J. Thomson figure out in the 1890's
discovered the nucleus and protons
discovered electrons
electrons aren't fixed on energy level
projected atoms through a glass tube
what did Ernest Rutherford figure out in 1890's
electrons aren't fixed on energy levels
discovered neutron , the first energy level can hold up 2 electrons and the second can hold 8
discovered the nucleus and protons
that all matter is made of tiny particles
what did Niles Bohr figure out in 1904-1908
discovered neutron , the first energy level can hold up 2 electrons and the second can hold 8
electrons aren't fixed on energy level
atoms are 3-D
discovered neutrons
what did creating the modern atomic model discovered
all matter are called atoms
discovered nucleus and protons
discovered neutron , the first energy level can hold up 2 electrons and the second can hold 8
atoms are 3-D, electrons aren't fixed on energy levels they float around them
how does ionic bonds form between two or more atoms
adding positive protons and subtracting negative electrons
the metals gives its valence electrons to the nonmetals
electons and protons = neutrons
what types of elements must be found in every ionic bond
metal and nonmetal
electrons and protons
positive and negatives
what does the Electron Dot Diagram do
(choose 3)
uses dots to represent the amount of neutrons and protons in an atom
uses the element symbol and a series of dots to represent number of valence electrons
shows us how many valence electrons each element has
put dots on a graph to show the energy levels
help us determine the oxidation number from each element
Ionic bonds are formed when electrons get
Shared between two atoms
Removed from both atoms
Transferred from one atom to another
Added to both atoms
An ionic bond is the attraction between: (Select ALL that apply)
oppositely charged ions
similarly charged ions
metals and nonmetals
neutral atoms
cations and anions
If I had an anion with a charge of 3- how would you describe the formation of that ion?
gained 2 electrons
lost 2 electrons
gained 3 electrons
lost 3 electrons
If I had a cation with a charge of 2+ how would you describe the formation of that ion?
gained 2 electrons
lost 2 electrons
gained 4 electrons
lost 4 electrons
