Structure of the Atom - Coggle Diagram
Structure of the Atom
Electron Shell
Layer capacity formula =2n^2
No of occupied main levels = No of the period in which the element is in
Has 7 layers
Not in the nucleus
Nucleus
Contains Protons and Neutrons
Is the whole mass of the atom
Held together by nuclear forces
Electronegativity
When an atom attracts electrons(how far right it is in the Periodic Table)(excluding noble gasses)
Symbol: X(ksi)
Atomic Radius
The distance between the nucleus and the outermost electron shell.
Details
Weights
Proton = 1 amu
Neutron = 1 amu
Electron 1/1860 amu
Symbols
Proton = p+
Neutron = n0
Electron = e-
Atomic numbers
Atomic Number - Symbol = Z
Z = # of protons
Atomic mass number - Symbol = A
A = # of protons + # of neutrons
If an element isn't an isotope of Hydrogen or Helium, it can't have more protons than neutrons
Gaining/Losing electrons(Ions)
Depending on where the atom is in the periodic table it either gains or loses electrons, which leads to it becoming either a cation or an anion(respectively)
Cation - Positive / Anion - Negative
To simplify - Metals lose electrons; Non-metals gain electrons
