Boron

Explanation:

The group III A is also known in the periodic table as group 13. The members of the group begin to appear in the second period.

At the beginning of this group III A is boron. Boron is a member of group III A as well as a member or period 2.

Boron is a metalloid and has only three valence electrons as other group III A elements.

wanahton purified a portion of water with 900 grams of contaminants. each hour, a third of the contaminants was filtered out.

let g(n) be the amount of contaminants (in grams) that remained by the beginning of the nth hour. g is a sequence, what kind of sequence is it, arithmetic or geometric? then, write an explicit formula for the sequence, g(n)=
