Metallic Bonding Metallic Bonding Why do metals conduct electricity? Metals conduct electricity. The delocalised electrons are free to move throughout the structure in 3-dimensions. They can cross grain boundaries. Even though the pattern may be disrupted at the boundary‚ as long as atoms are touching each other‚ the metallic bond is still present. Liquid metals also conduct electricity‚ showing that although the metal atoms may be free to move‚ the delocalisation remains in force until the

MATALLIC MENIRALS ROLL NO: 07 Metallic Minerals On an auspicious day‚ sometime around a million years ago‚ a member of the Homo habilis species stood erect and walked steadily on his two feet and his two hands became totally free. A new species – Homo erectus—began its journey on a new evolutionary track. This great change took around four million years after his ancestors – the hominids — broke free from the lineage of apes and chimpanzees. But ‚ perhaps for the next seven to eight hundred

It helps‚ in trying to see the periodic pattern‚ to know the pattern that results when we do a separation and analysis of all metal ions. PROCEDURE Procedure A 1. 2 drops of 6 M HCl was added to 1 ml of the mixture of the metal cations. 2. The suspension was centrifuged for 1 minute as ppt. of chloride was formed. 3. 1 additional drop of 6 M HCl was added to the clear

exchange of positive and negative ions between reacting solutions of two ionic compounds. Thus‚ in this example the precipitate must be either silver chloride‚ AgCl or sodium nitrate‚ NaNO3. Sodium nitrate dissolves readily in water and is therefore soluble. Thus we can conclude that silver chloride is the insoluble precipitate. We can represent the formation of this precipitate by a net ionic equation: Ag+ +NO3 ̄ +Na++Cl ̄→AgCl+NO3 ̄+Na+ Net: Ag+ (aq)+Cl ̄ (aq)→AgCl(s) Ions present in the solution but
