Electronegativity<span> is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most</span>electronegative<span> element) is assigned a value of 4.0, and values range down to caesium and francium which are the least </span>electronegative<span> at 0.7.</span>
Remember:
a^m * a^n=a^(m+n)
a^-m=1/a^m
8³ x 8⁻⁵=8³⁻⁵=8⁻²=1/8²=1/64<1
Answer: the student is not correct, because 1/64<1, and 8³ x 8⁻⁵=1/64.
Sorry I’m not sure but maybe you could look it up???
Answer:
