When lithium reacts with bromine to form the compound libr, each lithium atom: (1) gains one electron and becomes a negativelycharged ion(2) gains three electrons and becomes a negativelycharged ion(3) loses one electron and becomes a positivelycharged ion(4) loses three electrons and becomes a positivelycharged ion

Option (3) is the correct answer.

Explanation:

Atomic number of lithium is 3 and atomic number of bromine is 35. So, lithium has one extra electron whereas bromine has deficiency of one electron according to the octet rule.

Thus, when lithium combines with bromine then it results in the formation of ionic bond. That is, bond formed by transfer of electrons is known as ionic bond.

Thus, lithium loses one electron and becomes a positively charged ion.

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)=
