What is the force of attraction between electrons and the nucleus?

The attractive force between the electrons and the nucleus is called the electric force.

What is the force of attraction between two atoms called?

Chemical bond refers to the forces holding atoms together to form molecules and solids. This force is of an electric nature, and the attraction between electrons of one atom to the nucleus of another atom contributes to what is known as chemical bonds.

What happens when two atoms are close to one another?

This is called a double bond. When two oxygen atoms get close to each other, the attractions from the nucleus of both atoms attract the outer electrons. In this case, two electrons from each atom are shared. This is called a double bond.

When atoms are too close together is the force of attraction or repulsion stronger?

Two protons (or two electrons) will repel each other. And again, the closer together they are, the stronger the repulsion. Now the nucleus of an atom is positively charged, while electrons are negatively charged. As a result, a nucleus will attract electrons.

How does the attraction between two atoms changes as they form a bond?

As the atoms first begin to interact, the attractive force is stronger than the repulsive force and so the potential energy of the system decreases, as seen in the diagram. As the two hydrogen atoms move closer and closer together, the potential energy continues to decrease.

What force allows atoms to bond?

Chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electrostatic force of attraction between opposite charges, either between electrons and nuclei, or as the result of a dipole attraction.

Why do two atoms come together to form a covalent bond?

Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.

What happens when two electrons come close together?

But an interesting thing can happen when the two atoms get close together. The electron in each atom starts to notice the proton of the other atom. As a result, it becomes attracted not only to its own proton, but to the proton of the other atom as well. And electrons tend to repel each other.

When two atoms are separated and do not attract each other the potential energy is?

Consider two isolated hydrogen atoms that are separated by a distance large enough to prevent any interaction between them. At this distance, the potential energy of the system is said to be equal to zero (see Figure 1).

When two atoms approach each other and a bond is formed potential energy?

During the formation of a bond when atoms approach each other the potential energy decreases.

What force makes atoms stick together?

Similarly, the electrostatic force of attraction between the opposite charges (positive and negative charges) makes them stick together. The process by which force of attraction between the atoms or ions or opposite charges that makes them stick together is called chemical bonding.

What happens when two charged particles are placed close to each other?

If two charged particles of same charge are placed close to each other, they get repelled. On the other hand, if two charged particles of opposite charge are placed close to each other, they get attracted. The electric field around a charged particle is represented by some imaginary lines of force.

What makes an ionic bond stick together?

Ionic bond. The electrostatic force of attraction present between the oppositely charged atoms or ions makes them stick together. Generally, atoms are electrically neutral (have equal number of electrons and protons). However, if an atom loses or gains an electron it will become a charged atom or ion.

What happens when an atom gains an extra electron?

On the other hand, if an atom gains an extra electron, it will become a negatively charged atom or negative ion. When two opposite charged atoms (positive and negative ion) are placed close to each other, the electrostatic force of attraction present the two ions makes them sticks together.
