Which describes the polarity in a water molecule? A. partial negative charge on the oxygen atom because its electrons are pulled toward the hydrogen atoms

B. partial negative charge on the oxygen atom because it pulls electrons from the hydrogen atoms

C. partial positive charge on the oxygen atom because it pulls electrons from the hydrogen atoms

D. partial positive charge on the oxygen atom because its electrons are pulled toward the hydrogen atoms

The answer is B

B. partial negative charge on the oxygen atom because it pulls electrons from the hydrogen atoms

Explanation:

Oxygen has a charge of 6 so they need to pull 2 electrons from hydrogen, which creates a partial negative charge.

so she was walking and she stepped on warm jeffy , uh uh uhh dadye i just pooped my pants

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
