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.

If the half-life of a sample of a radioactive substance is 30 seconds, how much would be left after 60 seconds? <span>
A. one-fourth</span>
198 g of Glucose Is the answer.
Diffusion : a process in which molecules intermingle as a result of their kinetic energy of random motion
The primary cause of diffusion is : 3. Random internal motion of atoms and molecules
hope this helps
