Looking at the elements from period three, you can identify element 2 based on element 3. It shows that element 3 is Magnesium. The ionization energy increases as it goes from left to right.

Since Element 2 has a lower ionization, just think of an atom that is to the left of Magnesium because it has a lower ionization energy. The only atom to the left of Magnesium is Sodium. So element 2 is Na, or Sodium.

check:
if we double x2, r(new) =[2*x2][y]=2*[x2]*[y]=2*r
if we triple y, r(new) =[x2][3y]=3*[x2]*[y]=3*r

m_a_m_a [10]

Answer:

see explanation below

Explanation:

The question is incomplete. The missing parts are a) determine the electrophylic site. b) determine the nucleophylic site.

In order to do this, we need to write the reaction and do the mechanism. The nucleophylic site will be the site where the nucleophyle attacks to form the product. In this case the site is the carbon next to the bromine. In this place the Oxigen which is the nucleophyle goes. The electrophyle is the site where one atom substract to complete it's charges. In this case, the electrophyle is usually the hydrogen, so the site will be next to the oxygen after the nucleophyle attack.

You can see it better in the attached picture.
