What is a bond between positive metal ions and electrons in the metal called?
Hahaha E2020 Question huh....? The Answer is Metallic Bond.
What are some properties of metals with metallic bonds?
The atoms in metals like copper form METALLIC BONDS. There are three types of chemical bonds. So far, you know about ionic and covalent bonds. The third type of bond is called a metallic bond. Metals are the only elements that experience this type of bond. A metallic bond is a bond that holds atoms together in a metallic substance!!!Do you get it now? :D
What does a compound result from the chemical union of?
Compounds result from combining 2 or more elements chemically.
How is a metallic compound different from an ionic compound or a covalent compound?
Metallic compounds are very rare- substitutional alloys are not compounds (solid solutions) some alloy phases have a fixed stoichiometry. I suspect that you mean how do metals differ from ionic compounds or covalent compounds. metallic bonding involves delocalisation of electrons and in the case of metals other than the straightforward group 1, group 2 metals and Al some covalency. The sea of electrons is a good description of the delocalisation- and this leads to conductivity. Metallic compounds are high melting, the metallic bond is strong particularly in the transition metals. The metallic bond copes with deformation of the lattice- and metals are generally malleable and ductile. However some lattice defects do form and this causes brittle fracture - metals are quite complex! Ionic compounds consist of charged particles (atoms, polyatomic ions) that attract electrostaically and form rigid lattices. There are no electrons free to roam. Generally the ions are locked in place, so there is no electrical conductivity. the lattices are strongly bonded so they are high melting solids. The charged particles are potentially soluble in polar solvents such as water- so solubility is common. Covalent compounds fall into two groups - molecular where there are discrete units - giant covalent compounds where there is a lattice of covalent bonds. A very few of these, notably graphite, do have delocalised electrons that can conduct electricity. The molecular compounds generally have low melting points as the units are held together by intermolecular forces and do not conduct electricity. Covalent molecules may be polar or non-polar- and this affects there solubilty- like dissolves like is the rule, e.g. polar solvents disolve polar molcules
The difference between ionic compounds and covalent compounds?
An ionic bond is when one or more electrons are transfered from one atom to another. A covalent bond is when atoms share one or more electrons. The atom Hydrogen would need only 2 electrons but most need 8.
What type of bond does 2 iron atoms form?
The slightly positive charge on iron allows for what type of bond to oxygen that allows for transport from the lungs to the tissues
Are magnesium and fluorine ionic compounds?
An ionic bond is formed when a metal and a non-metal react. Electrons are transferred during this process. Magnesium is a metal and Fluorine is not. So, it forms an ionic bond. I don't believe there is such thing as a diatomic bond, only diatomic molecules which are 2 atoms of an element (O2, N2, etc) Metallic bonds are formed between metals. And in covalent compounds the atoms share the valence electrons.

What is the trend in ionic character of the group 2 compounds going down the group?
The ionic character increases for group 2 compounds as we go down the group. The metallic character also increases.
What elements are in metallic bonding?
Although the term "metallic bond" is often used in contrast to the term "covalent bond", it is preferable to use the term metallic bonding, because this type of bonding is collective in nature and a single "metallic bond" does not exist. Not all metals exhibit metallic bonding: one such example is themercurous ion (Hg2+2), which forms covalent metal-metal bonds.However the vast majority of metals have a metallic bond.

What are the 2 types of bonding What is the difference between them?
Types of bonding: ionic (in salts), covalent (in organic compounds), metallic (in metals).
How many different types of compounds are there?
Well depends what you mean by how many different types of compounds. In total? Or type 1 , and 2 etc. there is Type 1-Binary Compounds Type 2- Binary Trans-metallic Compounds Type 3- Binary Molecular Compounds Type 4- Ternary Compounds etc. these contains vast amounts of compounds so gives you an idea.
Properties of metallic bond?
The metallic bond is a delocalised bond with free electrons and also may include some covalent interaction This bonding is the cause of the luster, opacity, electrical conductivity, thermal conductivity, strength, malleability, ductility generally associated with the metals.
