Most metals are not brittle.
The lithosphere is composed of the crust and uppermost hard, brittle mantle.
Brittle deformation is most likely to occur in rocks that are hard and brittle, such as igneous rocks like granite or metamorphic rocks like quartzite. These rocks tend to fracture and break when stressed, resulting in brittle deformation.
It varies with the temperature. Glass is brittle at room temperature but becomes soft at high temperature. Glass also does not crystallize so it is considered a liquid even when cool. Spaghetti is brittle when dry but softens as water is absorbed.
: Separation of a solid accompanied by little or no macroscopic plastic deformation. Typically, brittle fracture occurs by rapid crack propagation with less expenditure of energy than for ductile fracture. :
Yes, most ionic compounds are brittle because their structure consists of layers of positively and negatively charged ions that do not easily slide past each other. When an external force is applied, the layers can easily shift and cause the crystal lattice to break, resulting in a brittle nature.
Most metals are not brittle.
Yes, the lithosphere is brittle as it consists of rigid outer layers of the Earth's crust and upper mantle. This brittleness contributes to the formation of faults, earthquakes, and other tectonic activities.
Brittle is neither a metal or nonmetal, it is a physical property of materials.Brittle is a property of a material. Most metals are not brittle but ductile and maleable.
The lithosphere is composed of the crust and uppermost hard, brittle mantle.

Some brittle stars breed asexually. Most brittle stars are either male or female however some species are hermaphroditic.
Brittle deformation is most likely to occur in rocks that are hard and brittle, such as igneous rocks like granite or metamorphic rocks like quartzite. These rocks tend to fracture and break when stressed, resulting in brittle deformation.
Ionic compounds are generally brittle because the ionic bonds within them are strong and rigid. When a force is applied, the layers of ions in the crystal lattice can shift and become misaligned, causing the structure to break instead of bending.
In order to answer this you need to understand the difference between the compositional layers of the earth and the physical layers. The crust and mantle are differing layers of the earth based on chemical composition. The lithosphere is a layer of the earth defined based on it's physical or mechanical properties (how it deforms). The lithosphere is composed of the crust and the portion of the upper mantle which deforms elastically and fails in a brittle manner (fractures can propagate through the material). So in the question where you ask is the crust and lithosphere brittle, the answer is yes as the crust is entirely part of the lithosphere which by definition is brittle. However as described above, a section of the upper mantle is also a brittle solid and so that too is part of the lithosphere. However below this, the mantle behaves as a ductile solid.
they are NOT good conductors of heat and they are brittle solids.
Selenium is the most brittle of the elements listed: The others are all full metals, but selenium is only a semi-metal or a metalloid, and ductility, the negative of brittleness, is a property primarily of metals.
