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.
Explanation:
The weight of an object on the surface of the earth is equal to the gravitational force exerted by the earth on the object.
which gives us an expression for the acceleration due to gravity <em>g</em> as
At a height h = R, the radius of a satellite's orbit is 2R. Then the acceleration due to gravity at this height is
Simplifying this, we get
A course of someone or something moving in a certain way
Heating the gas in an air balloon makes the balloon rise<span> because the </span>gas<span> in the</span>balloon<span> becomes lighter than natural </span>air<span>. The </span>heated gas<span> has less mass per unit of volume than that of the cool </span>air<span> surrounding the </span>balloon<span>. Hope this answers the question.</span>
