Answer:
Chemical bond - A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.
Electronegativity- Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons when forming a chemical bond. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.
Ionic bond -Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds.
Unit cell - the simplest polyhedron that embodies all the structural characteristics of and by indefinite repetition makes up the lattice of a crystal.
Ionic lattice - An ionic compound is a giant structure of ions. The ions have a regular, repeating arrangement called an ionic lattice . The lattice is formed because the ions attract each other and form a regular pattern with oppositely charged ions next to each other.
Crystal Covalent bond - A crystal in which the atoms are held together by covalent bonds. Covalent crystals are sometimes called macromolecular or giant-molecular crystals. They are hard high-melting substances. Examples are diamond and boron nitride.
Molecule- A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge.
Weak polar covalent bond -
Non polar covalent bond -A nonpolar covalent bond is a covalent bond in which the bonding electrons are shared equally between the two atoms. ... A nonpolar covalent bond is one in which the distribution of electron density between the two atoms is equal.
Strong polar covalent bond - An atom that shares one or more of its electrons will complete its outer shell. Covalent bonds are strong – a lot of energy is needed to break them. ... Both nuclei are strongly attracted to the shared pair of electrons in the covalent bond, so covalent bonds are very strong and require a lot of energy to break.
Binary ionic compound - A binary compound is a compound formed from two different elements. ... When naming binary ionic compounds, name the cation first (specifying the charge, if necessary), then the nonmetal anion (element stem + -ide).
Ternary ionic compound - In inorganic chemistry, a ternary compound is a compound containing three different elements. An example is sodium phosphate, Na3PO4. The sodium ion has a charge of 1+ and the phosphate ion has a charge of 3-. Therefore, three sodium ions are needed to balance the charge of one phosphate ion.
Polyatomic ion - A polyatomic ion, also known as a molecular ion, is a covalently bonded set of two or more atoms, or of a metal complex, that can be considered to behave as a single unit and that has a net charge that is not zero. Unlike a molecule, which has a net charge of zero, this chemical species is an ion.
Binary molecular compound -Binary molecular compounds are compounds that consist of exactly two nonmetal elements. ... The first element is given its element name; the second is given its root (hydr, bor, carb, ox, fluor, etc.) followed by ide.
Metallic bond Alloy -Metallic bond, force that holds atoms together in a metallic substance. ... The atoms that the electrons leave behind become positive ions, and the interaction between such ions and valence electrons gives rise to the cohesive or binding force that holds the metallic crystal together
