Im pretty sure th answer is D: temp differences on earth surface
Answer:
its outermost shell is completely full making it extremely stable.
Explanation:
It only has two electrons in its outer shell so its valence electron configuration is 1s2. Even though it only has two electrons, it is grouped with elements that have eight valence electrons. Helium is still happy because its outermost shell is completely full making it extremely stable.
Answer: Half-life of the substance is 16 years.
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample = 48 years
a = initial amount of the reactant = 240 micrograms
a - x = amount left after decay process = 30 microgarms
b) 
of reaction
Thus half-life of the substance is 16 years.
