How is a water molecule like a magnet simple?

Water molecules are polar in nature.

Explanation:

Water molecules are basically, #H_2O# molecules, which have bent shapes. Also, #O# atom is electronegative than #H# atom. So, the entire electron densities of the two hydrogen atoms get attracted towards the oxygen atom.
Thus a polarity develops in each #O-H# bonds, and thus, the water molecules are polar in nature and act like "little magnets".

If you were able to see a water molecule (H2O) up close, it would look somewhat like a round head with two ears positioned at the 10 and 2 o'clock positions. Think Mickey Mouse. The "ears" are the two hydrogen ions while the "head' is the oxygen ion. Because the hydrogen ions carry a positive charge and the oxygen ion a negative one, this arrangement gives the molecule a net polarity, much like a magnet. This feature of the water molecule gives water four properties that make it indispensable for life. It has cohesion and a comparatively high boiling point, it is less dense in the solid state than the liquid state, and it is an exceptionally good solvent.

Magnetic Attraction

The structure of the water molecule is a distorted tetrahedron. The hydrogen ions form a 104.5-degree angle with the oxygen molecule. The result is that, while the molecule is electrically neutral, it has poles, just as magnets do. The negative side of of one molecule is attracted to the positive side of those around it. This attraction is known as hydrogen bonding, and while it isn't strong enough to break the covalent bonds keeping the molecules together, it is strong enough to produce anomalous behavior that distinguishes water from other liquids.

Four Anomalous Properties

Cooks rely on the polar nature of water whenever they use a microwave oven. Because the molecules are like magnets, they respond to high-frequency radiation by vibrating, and the energy of these vibrations is what produces the heat to cook the food. This is one example of the importance of the polarity of H2O, but there are more important ones.

Cohesion: Because of the magnetic attraction water molecules exert on each other, liquid water tends to "stick together." You can see this when two water beads approach each other on a flat, smooth surface. When they get close enough, they magically merge into a single droplet. This property, called cohesion, gives water surface tension that insects with large feet exploit to be able to walk on the surface. It allows roots to suck water in a continuous stream and ensures that water flowing through tiny capillaries, such as veins, doesn't separate.

High Boiling Point: The boiling point of water isn't high when compared with some liquids, such as glycerin or olive oil, but it should be lower than it is. Compounds formed from elements in the same group as oxygen in the periodic table, such as hydrogen selenium (H2Se) and hydrogen sulfide (H2S), have boiling points that are 40 to 60 Celsius degrees below zero. Water's high boiling point is entirely due to the extra energy needed to break the hydrogen bonds. Without the magnetic attraction that water molecules exert on each other, water would vaporize at something like -60° C, and there would be no liquid water and no life on Earth.

Ice Is Less Dense than Water: The extra cohesion provided by hydrogen bonding compresses water together in the liquid state. When water freezes, electrostatic attraction/repulsion creates a lattice structure that is more spacious. Water is the only compound that is less dense in the solid state, and this anomaly means that ice floats. If it didn't, every marine ecosystem would die whenever the weather was cold enough for water to freeze.

Water Is a Universal Solvent: Because of its strong hydrogen bonding, water dissolves more substances than any other liquid. This is important for living beings that derive nourishment from nutrients dissolved in water. Most living beings also rely on electrolytes, which are water solutions containing ionic solutes, for transmission of bioelectric signals.

Answer

Verified

Hint: To answer this question we have to understand the structure and the polar nature of water molecules. Water is used as solvent for most of the reactions and it also plays a vital role in living organisms.

Complete answer:
Water is a simple molecule which consists of one oxygen atom bonded to two hydrogen atoms. The chemical formula of water is ${{H}_{2}}O$. Firstly, the structure of water was predicted to be linear but later with help of VSEPR theory it was found that the structure of water is bent. The structure of ${{H}_{2}}O$ is bent because of the presence of two lone pairs on oxygen.

How is a water molecule like a magnet simple?


The oxygen is more electronegative than hydrogen atom. So, the oxygen atom possesses a partial negative charge and the hydrogen atom possesses positive negative charge. Therefore, water is polar in nature.
Since it is polar in nature the oxygen atom which possesses partial negative ($-\delta $) can attract protons which possess positive charge or any element or atom that possess positive charge on it.
Same goes with hydrogen, which possesses partial positive charge ($+\delta $) and can attract oxygen in other water molecules or any other atom that possesses a negative atom.
Basically, when a magnet is brought nearer to another magnet it attracts each other. Unlike charges, they attract each other. This is the same that happens in case of Water molecules too.

This is the reason why the water molecule is said to act like a little magnet.

Note:
The polarity of water molecules the point that accounts for its mechanism as a little magnet. Since water molecules can form clusters as illustrated above they are used as solvent for many reactions. If the structure of the water molecule is linear the dipole moment in the water molecule will be 0. Since the water molecule has a bent structure it possesses some dipole moment.

How is a water molecule like a magnet quizlet?

Water is a polar molecule with a partially positive end and a partially negative end. The negative end of one water molecule attracts the positive ends of other water molecules surrounding it. Because of this attraction, the water molecules act like tiny magnets and cling to each other.

What kind of magnet is water?

Actually, what we said was consistent in all three answers. Water is "almost completely non-magnetic," which means the same thing as "too small to make a significant difference"or as "very little magnetism." There's a nice Wikipedia article on "diamagnetism" , which mentions the diamagnetic strength of water.

In what way are polar molecules similar to magnets?

A molecule with two poles is called a dipole and has a net dipole moment. A diatomic molecule that consists of a polar covalent bond, such as HF, is a polar molecule. The two electrically charged regions on either end of the molecule are called poles, similar to a magnet having a north and a south pole.
