The forces that hold atoms together are the electrical force and the strong force, which is stronger than the electrical force. The electrical force does the majority of the work of holding atoms together, but the strong force helps hold in the electrical force and can somewhat override it.Know More
The electrical charge that is exhibited from protons and electrons attracting to each other causes the force of the atoms to become stronger. The charge sets up the framework for the electrical force that is used to hold everything together, but it is not strong enough to keep the atoms close enough together. While the force helps electrons and protons attract to each other, it does nothing for the neutrons, which are neutral. It also works against itself because two protons and two electrons repel each other, even though they are pulling closer together through the electrical charge.
The strong force is able to remedy the problem of the electrical charge not being strong enough to hold everything together. It is stronger than the electrical force and helps to hold all of the protons and neutrons in, which are immune to the electrical force. It is a very strong force, but it only works in small ranges, making it ideal for holding atoms together. It is also able to override the repulsion that is sometimes caused by too many positive charges in an electrical force.Learn more about Atoms & Molecules
Intermolecular forces are the attractive forces between molecules that hold them together. There are four types of intermolecular forces: hydrogen bonds and ionic, dipole and induced dipole forces.Full Answer >
Ionic bonds hold atoms together using the electrostatic charge between their positive and negative ions. These ions are formed when electrons are transferred between atoms, the net loss or gain determining if the ion is positive, called a cation, or negative, an anion.Full Answer >
In 1905, Albert Einstein published an analysis in which he devised a mathematical way to predict the size of both atoms and molecules. At the time, the science of atoms was still in its infancy, but Einstein's test was crucial in leading the way towards testing the reality of atoms.Full Answer >
To determine an element's molar mass, it is necessary to add together the weight of all of the atoms present in the sample. The atomic weight of an element is printed inside the element's box on the periodic table. The molar mass is the atomic weight multiplied by the number of atoms per mole.Full Answer >
