Fracture - Apexvs
Minerals that do not have weak bonds along specific planes will tend to have a higher resistance to breakage and fracturing. This is because weak bonds along specific planes create areas of weakness where the mineral is more likely to break or split. Without these weak bonds, the mineral will have a more cohesive structure and be less prone to breaking.
no not all of them

Covalent network solids are generally not malleable. They have crystal structures that lack obvious glide planes and the covalent bonds are difficult to break and remake. This is a contrast with the metals where many of the crystal structures have glide planes and metallic bonds are relatively easy to break and remake.
Methane is a molecule with covalent bonds. Then again, there are different types of bonds. To be specific, Methane is a tetrahedral molecule with covalent long single bonds.
Sigma bonds lie along the bond axis - between any two atoms you can only have one sigma bond along the axis. Triple bonds encountered in organic chemistry have 1 sigma and two pi bonds( pi bons are "at right angles" to one another and the electron density is between the atoms but does not lie along the bond axis.
It is called cleavage.
cleavage.
Many minerals have "cleavage" that causes them to split on flat cleavage planes. Such minerals include micas (muscovite, biotite. phlogopite), calcite, gypsum, and feldspars. Cleavage is the result of the minerals' crystal structure that has weaker chemical bonds aligned in planes.
Cleavage depends on the arrangement and bonding of molecules. Minerals tend to split among the planes of weak bonds between their atoms. In specifying the cleavage properties of a mineral, scientists count the number of nonparallel planes of cleavage, and the angle between those cleavage planes.
When minerals break along certain planes, it is known as cleavage. Typically, the pieces will be the same form and be bounded by smooth, flat surfaces. Cleavage is determined by the number of cleavage directions and the angle(s) between them.If the mineral breaks in an irregular, jagged or splintered edge, it is said to have a fracture.
minerals with cleavage break along smooth, flat surfaces in one or more directions.
cleave
mineralogy is the study of minerals and a minerologist specifically studies minerals there chemistry, molecular bonds, miller indices, and assorted specific features of minerals.
It tells you that that mineral is smooth and flat ,and so are the chemical bonds. Because if it didn't it would be a fracture which means it is jagged and not smooth. I am sure of this answer because cleavage means physical property of some minerals that cause them to break along smooth, flat surfaces.
Cleavage is the tendency of materials to split along definite structural planes, yielding smooth surfaces. An example is shales or shists.
The property is referred to as cleavage or fracture, the tendency, or lack of tendency, of a mineral to break along planes of weakness. Some minerals have multiple planes of cleavage. Some have none, and are said to exhibit fracture.Cleavage is the tendency of a mineral to break along flat surfaces. The way in which a mineral breaks depends on how its atoms are bonded, or joined together. In a mineral that displays cleavage, the bonds of the crystal structure are weaker in the directions in which the mineral breaks.fracture is the tendency of a mineral to break into irregular pieces. Some minerals such as quartz break into pieces with curved surfaces. Other minerals may break differently-perhaps into splinters or into rough or jagged pieces. In a mineral that displays fracture, the bonds that join the atoms are fairly equal in strength in all directions. The mineral does not break along flat surfaces because there are no particular directions ofweakness in its crystal structure.
It means that the chemical bonds of the mineral aren't too strong along the lines and that when you break the mineral it'll break along those lines. please go to www.freewebs.com/mccniu (minerals aren't on it)
