What else can I help you with?
how does polymers?
The word 'poly' means many, therefore, a polymer is a long chain of molecules bound together by atomic forces.
What do dipole dipole forces do?
Hold polar molecules together
Do atomic nucleus contain molecules?
No, atomic nuclei do not contain molecules. Nuclei consist of protons and neutrons bound together by strong nuclear forces, while molecules are formed by the bonding of atoms through shared electrons in their outer shells.
What holds combinations of atoms together in molecules nuclear forces chemical bonds protons and electrons atomic magnetism?
Chemical bonds hold combinations of atoms together in molecules. These bonds, which include covalent, ionic, and metallic bonds, result from the interactions between the electrons of the atoms. Nuclear forces, on the other hand, operate within the nucleus to hold protons and neutrons together, but they do not influence the formation of molecules.
Identify the forces that hold atoms and molecules together at the atomic level Give an example of how these forces are involved in a chemical reaction?
Atoms and molecules are held together at the atomic level by the electromagnetic interactions between electrons, protons, and ions. For example, an ionic compound is held together by the attraction between the positive and negative charges of its constituent ions. Two atoms forming a covalent bond are held together by the mutual attraction they have toward one or more electrons. This interaction is quantized through the concepts of electronegativity and charge.
Why is the amount of energy necessary to keep atoms together?
The energy necessary to keep atoms together is primarily due to the electromagnetic forces that act between charged particles, such as protons and electrons. These forces create attractive interactions that hold atoms together within molecules and compounds. Additionally, nuclear forces, which operate at very short distances, are responsible for binding protons and neutrons in atomic nuclei. Overall, the balance of these forces determines the stability and structure of atoms and molecules.
Why are strong forces able to hold atomic nuclei together?
Strong forces are able to hold atomic nuclei together because they are powerful enough to overcome the electromagnetic repulsion between positively charged protons in the nucleus. These strong forces, also known as nuclear forces, are responsible for binding protons and neutrons together to form stable atomic nuclei.
Carbon tetrachloride CCl4 is nonpolar what forces hold the molecules together?
Van der Waals forces, specifically dispersion forces, hold the nonpolar CCl4 molecules together. These forces are caused by temporary fluctuations in electron distribution within the molecules, creating weak attractions between them.
How are atoms in molecules held together and what forces are responsible for maintaining their bond?
Atoms in molecules are held together by chemical bonds, which are formed when atoms share or transfer electrons. The forces responsible for maintaining these bonds are primarily the electromagnetic forces between the positively charged atomic nuclei and the negatively charged electrons. These forces include covalent bonds, where electrons are shared between atoms, and ionic bonds, where electrons are transferred between atoms.
Why do molecules stay together in outer space?
Molecules stay together in outer space due to intermolecular forces such as Van der Waals forces, hydrogen bonding, and electrostatic attractions. These forces help hold atoms together within molecules and molecules together in solid, liquid, or gaseous states, even in the vacuum of space.
What do the molecules in a liquid hold together?
The molecules in a liquid are held together by intermolecular forces such as hydrogen bonding, van der Waals forces, and dipole-dipole interactions. These forces are weaker than the covalent bonds within the molecules themselves, allowing the molecules to move past each other while still remaining close together.
What is a result of variations in the forces that holds molecules together?
