How do hydrogen and oxygen atoms form covalent bonds to create water? A: Oxygen gives its electrons to hydrogen. B: Hydrogen giv
2 answers:
<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
Covalent bond is formed when there is sharing of electrons between the atoms that are forming a bond.
When hydrogen and oxygen form a covalent bond to form a compound named water, both the atoms share electrons with each other.
Electronic configuration of Hydrogen =
Electronic configuration of Oxygen =
As, 2 electrons are required for one oxygen atom to complete its octet and 1 electron is required by the hydrogen to have a stable configuration. Therefore, 2 atoms of hydrogen shares its electrons to 1 atom of oxygen to form water.
The chemical formula for water is .
Hence, the correct answer is option C.

Answer:
Magnetic force,
Explanation:
Given that,
A beryllium-9 ion has a positive charge that is double the charge of a proton,
Speed of the ion in the magnetic field,
Its velocity makes an angle of 61° with the direction of the magnetic field at the ion's location.
The magnitude of the field is 0.220 T.
We need to find the magnitude of the magnetic force on the ion. It is given by :
So, the magnitude of magnetic force on the ion is .
