Question 1 how many valence electrons are in the methyl ion ch+3 ?

Valence are the electrons located in the outermost shell of an atom. Because they are attracted to the nucleus by a weak force, they are easily attracted to other valence electrons of other atoms. 

The Lewis structure of the methyl ion is shown in the picture. As stated in the Octet Rule, each element (except exceptions like Hydrogen) must have 8 electrons surrounding them. Each single bond contains 2 electrons. Therefore, there are only two electrons in the valence shell.

Iwould you figure it out but you don't have a picture or in your question as to what the physical property you're looking for is

The answer should be vaporization
