Spread out, usually in every direction.
Answer:
FALSE
Explanation:
Br is <em>bromine</em> with atomic number 35, mass number of 79.904 and belongs to the group 7 elements known as the halogens.
Ga is <em>gallium</em> with atomic number 31, mass number of 69.72 and belongs to the alkaline earth metal i.e the group 3 elements.
From the above and in terms of their mass number, it is evident that Br is the larger element compared to Ga which is lesser than Br. Hence the statement is FALSE
<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>
