It is a shell because the structure is with a hallow, curved shape
Because gasses have mass and therefore weight. As a soft drink loses CO2, it loses mass and therefore weight.
i feel like a uchia
The number of electrons in a shell varys depending on its location. The outer shell is usually paid the most attention to(the valence shell), and a stable outer shell (when considering a noble gas) bust have 8 electrons (with the exception of He). If there is less than 8 electrons, this is considered to be unstable, and makes it easier to lose electrons to other atoms.
Clear dots form.. then you can see the dots under light.. still white, egg shell decreases!
mass
it is a frame sturctures
a teepee is a frame structre
its a frame
its "MIXED" : shell,frame, mas. BUT u can say its shell if u didnt learn the word mixed.
mass
sheel
mass
eiffel tower is a frame structure.
shell because it is hollow and therefore represents the form of a shell which is also recognized as a shell structure
frame structure
the Eiffel tower is a definite frame. if the tower had something over the frame it would be a mass so the Eiffel tower would never be a shell if it had the framing still inside of it.
