because of the metling point of metals, it is difficult to just simply put metal together and have them to stay together without any type of glue or epoxy based creams.

wielding is used to melt the surface or even change the compound completely so they are able to combine with other metals.

same thing with atoms, you need a lot of heat, and speed to simply make salt or even copper because of the elements not really being favorable of each other.

Molecules of carbon dioxide are linear. What type of force exists between<br>these molecules?​
Vadim26 [7]

London Dispersion forces

Explanation:

London dispersion forces exists between the molecules of CO₂. These are weak attractions found between non-polar (and polar) molecules(symmetrical molecules).

  • This attraction sometimes makes non-polar molecules polar.
  • This is because of the uneven charge distribution caused by the constant motion of its electrons.
  • A temporary dipole or instantaneous dipole induces the neighboring molecules to become distorted and forms dipoles as well.
  • The forces are the weakest of all electrical forces.
