Attractive and repulsive forces arise due to the interactions between charged particles or objects. Attraction occurs when opposite charges attract each other, while repulsion occurs when like charges repel each other.

Attractive and repulsive forces are fundamental to understanding the interactions between charged particles or objects. These forces play a crucial role in various natural phenomena, ranging from the behavior of atoms and molecules to the dynamics of celestial bodies.
When it comes to explaining attractive forces between charged particles, the main driving force is the opposite charges they possess. According to Coulomb’s law, formulated by the French physicist Charles-Augustin de Coulomb in the late 18th century, the force of interaction between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Mathematically, this is represented as:
F = k * (q1 * q2) / r^2
Where F is the force of interaction, k is the electrostatic constant, q1 and q2 are the charges of the particles, and r is the distance between them. This inverse square relationship means that as the distance between charges decreases, the force of attraction increases exponentially.
To illustrate this further, we can consider the example of a positively charged proton and a negatively charged electron. Since they possess opposite charges, they attract each other. This attractive force is responsible for keeping electrons bound to atomic nuclei and is crucial for the formation of stable atoms.
On the other hand, repulsive forces occur between like charges. When two particles or objects carry the same type of charge, they exert a force pushing them away from each other. This repulsion is due to the fact that like charges repel, following Coulomb’s law.
A quote from Albert Einstein aptly captures the significance of attractive and repulsive forces in the natural world: “We still do not know one thousandth of one percent of what nature has revealed to us.” This highlights the intricate nature of the forces and phenomena that govern our universe, including the fundamental forces of attraction and repulsion between charged particles.
Interesting Facts:
- The two types of charged particles involved in attractive forces are protons, which carry a positive charge, and electrons, which carry a negative charge.
- Attraction and repulsion between charged particles are the basis for static electricity, which is responsible for phenomena like lightning and the shocks we experience after walking across a carpet and touching a metal surface.
- The electromagnetic force, which includes attractive and repulsive forces between charged particles, is one of the four fundamental forces in nature, along with gravity, weak nuclear force, and strong nuclear force.

| Charged Particles | Type of Force |
|---|---|
| Positive and Negative Charges | Attractive |
| Negative and Negative Charges | Repulsive |
| Positive and Positive Charges | Repulsive |
In conclusion, attractive and repulsive forces between charged particles or objects are governed by the interactions of their charges. The opposite charges attract each other, leading to attractive forces, while like charges repel each other, causing repulsive forces. These forces hold atoms together, influence the behavior of molecules, and are pivotal in numerous natural phenomena. As we continue to explore the depths of nature, the complexity and beauty of these forces become increasingly apparent.

In this video, the concept of bond energy and bond length in chemistry are discussed. The video explains that bond length is the distance at which the energy is minimized. It further explains that positive energy values indicate repulsion between atoms, while negative values indicate attraction. The video also delves into the forces of attraction and repulsion, such as proton-proton repulsion, electron-electron repulsion, and proton-electron attraction, that determine whether atoms move towards or away from each other. Understanding these forces is crucial in understanding the formation and stability of bonds between atoms.

Examples of non-contact forces include electric and magnetic forces. Objects having opposite charges experience an attractive electrostatic force, pulling them towards each other. Objects having the same charge experience a repulsive electrostatic force, pushing them away from each other.
According to the force-based approach, the attractive and repulsive forces between atoms arise from their subatomic structure and govern the behaviour of atoms and molecules. Therefore, a bond is formed due to electrical forces. The attractive and repulsive forces act simultaneously so that the atoms move closer and farther apart continuously.
If the two charges are of opposite signs, Coulomb’s law gives a negative result. This means that the force between the particles is attractive. If the two charges have the same signs, Coulomb’s law gives a positive result. This means that the force between the particles is repulsive.
A force is attractive if the objects interacting exert a pull on each other, creating a tendency to move closer. On the other hand, a force is repulsive if the interacting objects push each other away. Gravity is always attractive. That is why no matter where we are we feel a pull ‘downwards’ towards the centre of the earth.
Hint: When the electrons are shared by each atom to form a chemical bond force of attraction or repulsion is observed which as a result covalent bonding takes place. The covalent bond is observed between two nonmetal atoms.Complete step by step answer:In chemistry, the covalent bonds are formed between the two atoms or an ion where sharing of electrons takes place. The covalent bonds formed are also known as the molecular bond. The force of attraction or repulsion between the two atoms when they share a pair of electrons are known as covalent bonding.The covalent compounds are formed by two or more nonmetals atoms. You can see examples which include water ${H_2}O$, carbon dioxide $C{O_2}$ and ammonia $N{H_3}$. Most of the atoms have lower potential energy when they are bonded with each other and when they are separated. Let’s take an example of two isolated hydrogen atoms which are separated by a distance which is large enough to prevent any interaction between them. At this point the …
