Question

fill in the missing words
reactions that involve transfer of electrons between particles (atoms, molecules, ions) are called blank reactions.
reduction is the blank of electrons. oxidation is the blank of electrons.
a substance that accepted electrons from another substance and itself got reduced is called a(n) blank.
a substance that donated electrons from another substance and itself got oxidized is called a(n) blank.

Explanation:

Reactions involving electron - transfer are redox reactions. Reduction is gain of electrons, oxidation is loss of electrons. A substance that accepts electrons and gets reduced is an oxidizing agent. A substance that donates electrons and gets oxidized is a reducing agent.
