What is bonding adhesive used for?
Adhesive bonding is used to fasten two surfaces together, usually producing a smooth bond. This joining technique involves glues, epoxies, or various plastic agents that bond by evaporation of a solvent or by curing a bonding agent with heat, pressure, or time. Historically, glues have produced relatively weak bonds.

How are compounds formed?
A compound is a chemical species that is formed when two or more atoms join together chemically, with covalent or ionic bonds . Compounds may be categorized according to the type of chemical bonds holding the atoms together: Molecules are held together by covalent bonds. Ionic compounds are held together by ionic bonds.
What are some examples of compounds?
Examples of compounds include table salt or sodium chloride (NaCl, an ionic compound), sucrose (a molecule), nitrogen gas (N 2, a covalent molecule), a sample of copper (intermetallic), and water (H 2 O, a covalent molecule).
How are molecules held together?
Molecules are held together by covalent bonds. Ionic compounds are held together by ionic bonds. Intermetallic compounds are held together by metallic bonds. Complexes are often held together by coordinate covalent bonds. Note that some compounds contain a mixture of ionic and covalent bonds.
What is the first atom in a compound?
By convention, when atoms form a compound, its formula lists the atom (s) acting as a cation first, followed by the atom (s) acting as the anion. This means sometimes an atom may be first or last in a formula. For example, in carbon dioxide (CO 2 ), carbon (C) acts as a cation. In silicon carbide (SiC), carbon acts as the anion.
What are some examples of compounds that are not considered compounds?

What type of bonding occurs when a metal is bonded to a non-metal?
Ionic bonding. Ionic bonding occurs in compounds that contain a metal (usually a Group 1 or 2 elements) with a non-metal (usually a Group 6 or 7 element). They bond to form metal compounds. electrons are transferred from the metal atom to the non-metal atom. this forms oppositely-charged ions.
What are the three main ways atoms and ions bond?
Atoms and ions bond with each other in three main ways – ionic bonds, covalent bonds and metallic bonds. Different types of bonds form different types of structures – lattices and molecules.
