Hello!
<span>The air inside the building is easily pressed out the windows because the air is composed of widely spaced molecules in the gas phase.
The word "gas" was created by the Netherlandish scientist Jean Baptista van Helmont from the Latin word "chaos". The gas phase consists of molecules with high kinetic energy, that adopt the shape of the container and tend to expand. The molecules are essentially free, and the gravitational pull on them is negligible.
Have a nice day!</span>
The rocket works on the principal of action and reaction. Newton's third law of motion.
The metals are the elements that more easily can lose electrons to fill their outermost shell. And among the metals the alkalyne are most likely than alkalyne earth and these are most likely than other metals.
As less electrons the metal has in its outermost shell the more likely it will lose an electron fo fill its outermost shell.
So, Li, Na, K, Rb, Cs, and Fr have one electron in their outermost shell, so they are more likely to lose an electron to fill their outermost shell than Be, Mg, Ca, Sr, Ba, Ram which have two electrons in their outermost shell.
Using the same reasoning, Be, Mg, Ca, Sr, Ba, Ra are more likely to lose an electron to fill its outermost shell than Al, Ga, In, Tl.
Al, Ga, In, Tl are more likely to lose an electron than Si, Ge, Sn, Pb.
Si, Ge, Sn, Pb are more likely to lose an electron than O, S, Se, Te, Po
O, S, Se, Te, Po are more likely to lose an electron than F, Cl, Br, I, At
F, Cl, Br, I, At (halogens) and He, Ne, Ar, Kr, Xe, Rn (noble gases) will not likely lose electrons.
