Chapter 1- Atomic Structure Flashcards
Atomic number is…
Amount of protons
Mass number is…
Protons and numbers
Atoms with different mass numbers (neutrons) are called…
Isotopes
An atom is overall…
Neutral
Proton-
+1 mass is 1
Neutron-
0 mass is 1
Electron-
-1 mass is 0 (0.00005)
Dalton-
All matter is made of atoms, bonding two atoms together make a compound
J.J. Thompson…
Found out electron
Rutherford…
Found out that there is a nucleus in the middle of atom
Bohr…
Has a more scientific view of the rest of them
what is the equation for a displacement reaction? what is an example of that?
less reactive metal oxide + more reactive metal –> more reactive metal oxide + less reactive metal.
copper oxide + carbon –> carbon oxide + copper
what is an alloy?
when metals are mixed together, such as brass, or bronze
what is the reactivity series?
magnesium pottasium carbon iron copper
what is bioleaching?
the extraction of metal ores by microorganisms oxidising them
