Use what you know about valence electrons and the octet rule to explain why alkali metals are more likely to lose electrons than gain them.

Alkaline metals, for example, would find it much easier to lose electrons than gain electrons, so they are not very electronegative. ... This is also the reason why metals have a high electrical conductivity (i.e. their electrons are can easily move from atom to atom

Ch4 is nonpolar and insoluble in water. since all of the hydrogen atoms are evenly spread around the carbon atom even through the c h bond is polar all the poles cancel each other out.
