Answer:
[Na]^+ [Cl]^-
Explanation:
Lets say its sodium, its number of electrons is 11, but when its stable (an ion), it is 10. and chloride, number of electrons is 17, but when its stable (an ion) it is 18. So the lewis structure for that is, remember with the straight brackets (not sure what it's called, but you know what I mean I guess) its this one: [ ]
Sodium will be + because it has more protons (11-10 = +1), and chloride will be - because it gained an electron, so has more electrons than protons (17-18 = -1)
So the lewis structure would be:
[Na]^+ for sodium
and
[Cl]^- for chlorine
Sodium chloride:
[Na]^+ [Cl]^-
Also just to add, only 1 of each atom (Na and Cl) was needed for the bonding, but if let's say example; 2 Cl was needed to bond with sodium, there would be 2 Cl (same) and 1 Na.
Explanation:
The observation that can make the chemist conclude that the liquid is a pure substance is if the unknown liquid composition is the same at every point of sampling.
- Pure substances are distinct substances.
- They have a definite composition.
- All the parts are the same throughout.
- They cannot easily be separated or broken down into simpler substances by physical means.
- They have a unique set of physical properties.
Therefore, if his analysis meets any of the criteria for defining a pure substance above, he can conclude that it is one.
Pure substances are elements and compounds.
