Question

reduction involves the ______ of electrons.
o gain
o bonding
o displacement
o loss
question 24
what is the oxidation number for fluorine in f₂?
o 0
o -1
o -2
o +1

Explanation:

1. In redox - chemistry, reduction is defined as the gain of electrons. Oxidation is the loss of electrons. So for the first question, the key concept is the definition of reduction.
2. For the second question, in a free element (an element in its elemental form), the oxidation number is 0. Fluorine in \(F_2\) is in its elemental form.

Answer:

1. A. gain
2. A. 0
