The electron movement towards the chlorine atoms mostly lead to ionic bonding in sodium chloride.

Explanation

Sodium chloride is an ionic bond compound.

Ionic bonding usually occurs between elements having high difference in their electronegativities.

Here chlorine is highly electronegative compared with sodium.

The atomic number of sodium is 11 and the atomic number of chlorine is 17. So the electronic configuration of sodium is [Ne] 3s1 and the electronic configuration of chlorine is [Ne] 3s23p5.

So from this, it can be confirmed that sodium has extra one electron in the 3s shell which is ready to combine with another element.

The one electron in the outermost shell of sodium is loosely bonded with the nucleus and it has a tendency to bind with other element to attain a stable state.

So sodium is electropositive in nature and its charge is Na+. Similarly the electronic configuration of chlorine indicates that it requires an electron to stabilize itself on the basis of octet rule, i.e, the outermost shell will be filled with 8 electrons when one electron will be added in chlorine.

So chlorine has the tendency to attract electrons and hence denoted as Cl-.

So the one loosely bond electron in the outermost shell of Na transfers to the outermost shell of Cl, stabilizing both the elements and forming a compound of NaCl by ionic bonding between them.

The answer to your question really depends on three things: how much water you have, how cold it is to start out, and how cold the things around it are. water actually freezes when it gets to 32 degrees fahrenheit (0 degrees celsius), but the time it takes to get there may be different. let's start with the first. if you take two glasses, and fill one with a tiny bit of water, and the other about halfway, then put them both in the freezer, the one with less water will freeze first (you can try this at home, but i recommend using plastic cups and not glass ones). now let's move on to the second part. let's say you have two glasses, and you fill one with really cold water that has been in the refrigerator, and the other with really hot water from the sink. if you put both of them in the freezer, the one that started out colder will freeze first. for the third part, let's imagine that you have two glasses with the same amount of water in them, and the water is at the same temperature. imagine putting one outside on a really really cold day in georgia, and having a friend in alaska put one outside on the same day. since it would be so much colder in alaska, the glass of water there would freeze before yours. so, if you took a tiny bit of really cold water in a glass, and put it outside on a cold day in alaska, it would freeze a lot faster than a big glass of hot water outside on a cold day in georgia.

Use a magnet to separate iron, evaporate water, i'm not sure how to separate the other two i'm sorry but good luck
