Gabriel is studying a newly discovered element. Through his work, he has proven that this element can exist in the form of 3 different stable isotopes: X - 413, X - 415, and X - 416. He has determined that the natural abundance for each isotope is 62%, 24%, and 14%, respectively. Which of the following would most likely be the average atomic mass for this element?

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a
