What is the number of electrons shared between the atoms in i2 molecule (that is an i not a 1) 1) 7 2) 2 3) 8 4) 4

Iodine is one of seven elements that usually form as diatomic molecules. These other "diatomics" are  and . They typically bond to themselves.

Iodine has seven valence electrons. Using valence shell electron pair repulsion (VSEPR) theory, we can predict the Lewis dot structure for . We see there are fourteen electrons, and we can make a covalent bond, leaving three lone pairs on each atom. The bond replaces two electrons, so the number of electrons shared is two.

Ithink this is what you meant. the temperature at which a liquid begins to boil is called the boiling point. the boiling point of water is 212°f or 100°c.  and at that point will start to turn into steam (gas)
