Answer:
One.
Explanation:
this is the structure of lithium which has valency 1 .Valency means no.electrons present in outermost shell or needed electrons to complete octet
The correct answer is approximately 1.95g. First, take (1.022*10^10)/(1.277*10^9). This is the same as time elapsed/half-life. This gives you 8, which is the number of half lives. Then multiply mass (500.3g) by (1/2)^8, resulting in 1.95g, which is the answer.
