The electron cloud model, also known as the quantum mechanical model, describes electrons as existing in regions of space around the nucleus called electron orbitals or electron clouds. These electron orbitals are three-dimensional probability distributions that represent the likelihood of finding an electron at a specific location.
According to this model, electrons do not follow precise paths like planets around the sun in a classical sense. Instead, they exist in a state of probability and can be found within certain regions around the nucleus with different levels of energy. These regions are defined by the principal quantum number (n), which corresponds to the electron's energy level or shell, as well as other quantum numbers that specify the shape, orientation, and spatial distribution of the orbitals.
Electrons are considered to have both particle-like and wave-like properties, and their behavior is described by the principles of quantum mechanics. The electron cloud model provides a more accurate and comprehensive description of the behavior and distribution of electrons in an atom compared to the older Bohr model, which depicted electrons as orbiting the nucleus in specific paths.
Hence, the electrons are described by the electron cloud model.

Answer: malleability and ductility
Explanation:-
Malleability is the property of metals to be beaten into sheets. Ductility is the property of metals to be drawn into wires.The delocalized sea of electrons enable the metal atoms to roll over each other when stress is applied and thus they can be converted to sheets or wires.
Shininess of metals is because electrons on the surface can bounce back light at the same frequency as the light hits the surface.
When a wire is connected to a metal, the delocalized electrons are drawn to the positive pole and thus helps in the conduction of electricity.
The metallic properties that are caused by atoms rolling over each other in metallic bonds are malleability and ductility.the atoms that are being rolled over are delocalized electrons in the sea of electrons in the metallic bond enable them to roll over when stress is applied.
