A bond between 2 nonmetal atoms that have the same electronegativity and therefore have equal sharing of the bonding electron pairExample: In H-H each H atom has an electronegativity value of 2.1, therefore the covalent bond between them is considered nonpolar. Nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
The attachments dont work, they say that they have been taken down or sum... ?
Answer:
Number of moles (n)=
molecular weight
weight
Weight=n×Molecular weight
=0.5×14
Mass=7g
