Refer to the following illustration. How many hydrogen atoms could bond with oxygen?
WITCHER [35]
2. 

The reason why is because there are 2 available electron spots on the orbital for the oxygen atom. Hydrogen atoms have one proton and one electron, thus, in order to fill the oxygen atom orbital to a full outer shell, a maximum of 2 atoms could bond with the oxygen atoms. 

6 electrons (oxygen)+ 1 electron (hydrogen)+ 1 electron (hydrogen)= 8

Anvisha [2.4K]

Answer:

We have the final answer as

4.69 \times  {10}^{ - 19}  \:  \:  J

Explanation:

To find the energy of a photon of this light we use the formula

<h3>E = hf</h3>

where

E is the energy

f is the frequency

h is the Planck's constant which is

6.626 × 10-³⁴ Js

From the question

f = 7.08×10¹⁴ Hz

We have

E = 7.08×10¹⁴ × 6.626 × 10-³⁴

We have the final answer as

4.69 \times  {10}^{ - 19}  \:  \:  J

Hope this helps you
