Resource summary

Fundementals in Chem
1 Atoms and Elements
1.1 Atom
1.1.1 protons
1.1.1.1 overall charge of +1
1.1.1.2 Inside Nucleas
1.1.2 Nucleas
1.1.2.1 Neutrons
1.1.2.1.1 overall charge of 0
1.1.3 Electron

Annotations:

  • Travels around in shells. Shells are energy levels. 
1.1.3.1 overall charge of -1
1.1.3.2 shells

Annotations:

  • 1st shell - 2 electrons 2nd shell- 8 electrons 3rd shell - 8 electrons
1.1.3.2.1 Bonding
1.1.3.2.1.1 Covalent Bondiing

Annotations:

  • Sharing of electrons
1.1.3.2.1.1.1 Molecules
1.1.3.3 Ions

Annotations:

  • When atoms lose or gain electrons they form positive or negative ions
1.2 element

Annotations:

  • 1 or more of the same type of atom 
1.2.1 Compound
1.2.1.1 Ionic Bonding

Annotations:

  • Metal loses an electron to form a positive metal ion. Non metal gains elctron lost by metal to form a negative ion compound
2 The periodic Table
2.1 Atomic Number

Annotations:

  • How many protons are in the nucleas
2.2 Mass Number

Annotations:

  • How many protons and electrons are in the atom
2.3 Groups

Annotations:

  • Groups in the periodic table show how many electrons are in the outside shell of the atom of that specific element in that group
  • All elements in one group have got similar properties
