what is a coordination bond?
150276
A coordination bond is a bond where one molecule gives both electrons to form a covalent bond. It differs from an ionic bond because the electrons are "shared" not given (e.g. the bond consists of a wavefunction, instead of discrete cations and anions)

u do, ionic bonds results not from a sharing of electrons but from a transefer of one of more electrons from one atom to another

Where a bond (usually a C-H bond on a ligand to a metal complex) actually becomes a donating species to the metal.

There are lots of reasons why there are large number of organic compounds .I’m giving U few of them.\nCatenation: The tendency of an element to form chains of identical atoms is called catenation. This tendency is observed in the case of non-metals showing covalency of two or more. However, this property is maximum in carbon as it can combine with other carbon atoms by single, double or triple covalent bonds. The bonding can be extended to form long open chain (straight or branched) or closed ones. Catenation property depends upon the value of bond energy which is maximum in the case of carbon. \nBond:                                         C-C    Si-Si       S-S     P-P     N-N    O-O\nBond energy:                              83        54         54        50      39        35          (approximately)\n(kcal/mol)\n The stability or the strength of the bond decreases as the bond energy decreases. Hence, the tendency of catenation decreases in the following manner; C> Si ~ S > P > N > O\nTendency to combine with other non-metals: Carbon has the ability to form strong covalent bonds with many other atoms such as H, O, S, N, Cl, Br, I, etc. The C-C bond energy is approximately equals to the magnitude of bond energies between carbon and various other atoms.\nBond                                          C-C         C-H       C-O      C-Cl      C-N       C-Br\nBond energy                               83.0         97.0       86.0      81.0       73.0       68.0           (approximately)\n(kcal/mol)\nIsomerism is one of the reason also.

Covalent bond: bond in which one or more pairs of electrons are shared by two atoms.\n\nIonic bond: bond in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other.

Determining structure of molecules.\nIonic structures- The Alkali metal halides are ionic compounds e.g NaCl. Na has a positive charge whereas Cl has a negative charge.\n\nMolecular solids- are held by weak bonds called Van Der waals forces. \n\nMacromolecular structures or giant molecular- have covalent bonds between atoms, these bind all the atoms into a giant molecule e.g Diamond

The simple answer is probably: covalent bond\n\nI quote: "Covalent bonding is an intramolecular form of chemical bonding characterized by the sharing of one or more pairs of electrons between two species, producing a mutual attraction that holds the resultant molecule together. Atoms tend to share electrons in such a way that their outer electron shells are filled. Such bonds are always stronger than the intermolecular hydrogen bond and similar in strength to or stronger than the ionic bond."

Covalent bonding is a form of chemical bonding characterized by the sharing of one or more pairs of electrons by two atoms in order to produce a mutual attraction; atoms tend to share electrons so as to fill their outer electron shells . Such bonds are always stronger than the intermolecular hydrogen bond and similar in strength or stronger than the ionic bond . Commonly covalent bond implies the sharing of just a single pair of electrons. The sharing of two pairs is called a double bond and three pairs is called a triple bond. Aromatic rings of atoms and other resonant structures are held together by covalent bonds that are intermediate between single and double. The triple bond is relatively rare in nature and two atoms are not observed to bond more than triply. \n\nCovalent bonding most frequently occurs between atoms with similar electronegativities where neither atom can provide sufficient energy to completely remove an electron from the other atom. Covalent bonds are more common between non-metals whereas ionic bonding is more common between two metal atoms or a metal and a non-metal atom.

False.\n\nIonic bonds form when 1 or more electrons from one atom are transferred to the electron cloud of another atom.  Leaving one with a net positive charge while the other has a net negative charge.  These two opposing charges will be attracted to each other, resulting in an ionic bond.

Because they effectively bind to but also dissociate from the metal center.  They protect the metal from reaction with undesired things until something which is a better ligand comes along and knocks it off.\nIt also serves to generate low-valent or even zero-valent forms of the metal (such as palladium tetrakis).

Charges on transition metals are determined based on the ligands, or other molecules, that are bonded to the transition metal.  Transition metals are considered to have 2+ charge in their solo state.  Since transition metals can have a variety of charges, they are very stable and versatile when it comes to ligand choice.

In Ionic bond, elements looses or gains electron(s) and become ions and the electrostatic potential of these ions bind them\n\nIn covalent, the participating elements are bound by sharing electrons between them.

Ionic bonds are a type of chemical bond based on electrostatic forces between two oppositely-charged ions.\n\nCovalent bonding is a description form of chemical bonding that is characterized by the sharing of one or more electrons between two atoms. In general bonds are defined by a mutual attraction that holds the resultant molecule together. Often bonding occurs in such a way that the the outer electron shells of the participating atoms becomes filled. Such bonds are always stronger than the intermolecular hydrogen bond and similar in strength to or stronger than the ionic bond......;

Chemical bonds form when electrons are shared, like in covalent bonds.  The atoms in the bond share a certain number of electrons between them usually so they both have a complete octet of electrons.  Another type of bond is ionic.  This is when one atom completely pulls off an electron from the other atom.  This results in a negative charge on the taker and a positive charge on the giver.  The bond is formed by the electromagnetic force acting between these two dissimilar charges.

1)ionic and covalent depend on the situation and are considered generally equal \n2)network bonds are a type of covalent bond\n3)metallic bonds are weaker (this one's kinda fuzzy)\n4)intermolecular are the weakest
