China Vanke, the largest real estate developer in the worldâs second largest economy announced today that it has broken ground on a new project in New York City with US-based partners Hines and RFR Holdings.he move by the Shenzhen-based property giant comes as part of a drive to diversify into new markets that last year saw Vanke launch overseas projects that include a $620 million joint project in San Francisco with Tishman Speyer, as well as deals in Hong Kong and Singapore.
1 A metal is a lattice of positive metal 'ions' in a 'sea' of delocalised electrons. 2  Metallic bonding refers to the interaction between the delocalised electrons and the metal nuclei. 3  The physical properties of metals are the result of the delocalisation of the electrons involved in metallic bonding.he strength of the metallic bond depends on the. 1  number of electrons in the delocalised 'sea' of electrons. ( 2 More delocalised electrons results in a stronger bond and a higher melting point.). 3  packing arrangement of the metal atoms.
A covalent bond is formed between two non-metals that have similar electronegativities. Neither atom is strong enough to attract electrons from the other. For stabilization, they share their electrons from outer molecular orbit with others. An ionic bond is formed between a metal and a non-metal.Non-metals(-ve ion) are stronger than the metal(+ve ion) and can get electrons very easily from the metal. These two opposite ions attract each other and form the ionic bond.he covalent bond is formed when two atoms are able to share electrons whereas the ionic bond is formed when the sharing is so unequal that an electron from atom A is completely lost to atom B, resulting in a pair of ions. Each atom consists of protons, neutrons and electrons.
