In molten lava like all the rest.
Hope it helped!!!
The CH4 molecule has the lowest molecular weight, so it has the lowest boiling point.
Hope I helped :)
What??? what language is this?
The correct option is this: SODIUM IS VERY REACTIVE BECAUSE IT DOES NOT HAVE A FULL VALENCE SHELL.
For an atom to attain an octet form, it must have eight electrons in its outermost shell. Elements with eight electrons in their outermost shells are un-reactive. Sodium has only one electron in its outermost shell, this makes it to be very reactive because it is very willing to react with suitable elements in order to become stable.
