Answer:
Crystalline solid
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification.
Deliquescence
becoming liquid, or having a tendency to become liquid.
Covalent bond
A covalent bond is an intramolecular interaction in which two atoms share electrons to fill their outer electron shell.
A simple example is hydrogen (H2). Its outer shell is capable of holding two electrons, but a single hydrogen atom has only a single electron. By bonding with another hydrogen atom, each can complete its outer shell and achieve stability by sharing the two electrons. Additionally, all halogen elements (group 17) form diatomic molecules with covalent bonds.
