The answer is 8 :)
All nobel gases have 8 outer electrons.
Answer:
B. Alpha
Explanation:
Alpha decays always split into an element and He.
Beta decays always split into an element and e- (eletrons).
Gamma decays always split into an element and radiation.
Electric
current passes through a filament of an incandescent bulb, thereby increasing
it temperature. When current flows, it contains electrons through the filament
to produce light. Typically, incandescent light bulb consists
of a glass enclosure that contains tungsten filament. The glass enclosure
contains either a vacuum or an inert gas that serves as the filament protection
from evaporating. Incandescent light bulbs contain a stem attached at to its
base to allow the electrical contacts to run through the envelope without gas
or air leaks.
Scientists at NatureWorks of Minnetonka, Minnesota, makes food containers from a polymer called polylactic acid, made using microorganisms to convert cornstarch into a resin. The resulting polymer is used to replace rigid petroleum-based plastic used in yogurt containers and water bottles.
