<span>
</span>The solution would be like this for this specific problem:

<span> (atomic number) - (core electrons)</span> 

Boron:

Atomic number: 5 
Core electrons: 2

Boron will have the following: 2 core electrons and 3 valence electrons.
(atomic number) - (core electrons)------> (5) - (2) = +3 

<span>
</span><span>Oxygen: </span><span>
<span>Atomic number: 8 </span>
<span>Core electrons: 2 </span></span>

<span>Boron will have the following: 2 core electrons and 6 valence electrons. </span><span>
<span>(atomic number) - (core electrons)------> (8) - (2) = +6 |

So the answer would be +3 and +6</span>.</span><span>

I hope this helps and if you have any further questions, please don’t hesitate to ask again. </span>

How can students help reduce pollution?

Help Recycling

The most obvious things to reuse are plastic, glass, metal, and paper or fabric (paper and organic fabric are made of the same component, cellulose, and are recycled in a similar way). The color-coded trash bins show where each of these components can be put to be recycled in a proper way.
