Why did the scientist use 2 different methods to create NaCl? 1. They wanted to create a more than just sodium chloride

2. They wanted to see the erlenmeyer flask glow

3. They wanted to obtain a purer product

explanation:

detials on each model with digrams

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
