A. O–H bonds are polar covalent, and hydrogen pulls the shared electrons toward it.

B. O–H bonds are nonpolar covalent, and oxygen pulls the shared electrons toward it.

C. O–H bonds are nonpolar covalent, and hydrogen pulls the shared electrons toward it.

The statement that best describes the type of bond a molecule of water has and how the electrons behave is : O–H bonds are polar covalent, and oxygen pulls the shared electrons toward it; option D

<h3>What are covalent molecules</h3>

Covalent molecules are molecules which are formed by the sharing of electrons between atoms of two or more elements whose elecyronegativity values are close to each other.

Covalent bonds are usually formed by non-metals such as hydrogen, oxygen, nitrogen to form their gases.

Example of covalent molecules include water and hydrogen gas.

<h3>What are Polar molecules</h3>

Polar molecules are molecules which are formed by the uneven sharing of electrons between atoms or by the formation of ions by substances such that the two ends of the molecule will have different charges, positive and negative.

In polar covalent molecules, the more electronegatibe element pulls the shared electrons more to itself. For example, in a water molecule which is polar, oxygen pulls the shared electrons with hydrogen more to itself to have a partial negative charge while the hydrogen atom has a partial positive charge.

Therefore, statement that best describes the type of bond a molecule of water has and how the electrons behave is : O–H bonds are polar covalent, and oxygen pulls the shared electrons toward it; option D

Answer:

see below

Explanation:

1. One atom pulls an electron from another atom.

2. Forming bonds releases energy and is exothermic.

3. Additional bonds require more energy to break, so the bond energy is higher.

4. −153

5. O–H bonds are polar covalent, and oxygen pulls the shared electrons toward it.

What is the dropped down number in a chemical formula that tells the number of atoms of a particular element? *
densk [106]
The lack of a number preceding the carbon symbol C and the compound formula CO2 shows that there is one carbon atom and one carbon dioxide molecule. Subscript numbers in chemical formulas represent the number of atoms or molecules immediately preceding the subscript.
