Answer: 20mol CO2
Explanation:
<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>
