Before bonding, what is oxidation state?

# data[].attributes.body
N2==0
O2=0
H2=0
After bonding, transferring , sharing electrons, the oxidation state changes.
If the oxidation state increased, Oxidation
If the oxidation state decreased, reduction

When Ca, reacts with Cl to form CaCl2, which was oxidized, and which was reduced?

Which is oxidized and which is reduced?
Zn + Pb +2    =  Zn ⁺²+  Pb

Which is oxidized, reduced? Why?
Cu²⁺  + 2e- = Cu
Fe =  Fe ³⁺ + 3e-

Determine the Oxidation state of  the element IN Bold:
CH 4
Na₂ CO3

Changes in oxidation state:
Consider this reaction:
Zn + Fe²⁺ = Zn²⁺  +  Fe
Which one was the oxidation state increased?
Which one was reduced?
