surrounded by other molecules or ions weakly or more strongly bonded to it. The surrounded ions or molecules are called ligands. Ligands acts as Lewis base. It is attached to the centre metal ions by providing lone bond pairs to it. The active metal acts as Lewis acid‚ accepting electron lone pairs from ligands. The bonding which attach ligands and the centre metal ion together is coordinate bond or dative bonds. It is a type of covalent bond where the ligands shares its lone paired electrons with the centre

History of childcare In this report I will be looking at the history of the childcare industry on how children had been looked after back in the day to today’s industry. In history the first day care centre appeared in France about the 1840‚ and the societe des crèche was recognised by the French government in 1869.organising in Europe in the late 18th and early 19th century day cares were established in the United States by private charities in the 1850’s. The first being was the New York day

VSEPR stands for ¡°Valence Shell Electron Pair Repulsion¡±‚ the theory is used for predicting the structure of molecules. The theory can be used in two main steps. First‚ the number of all bonding pairs and lone pairs is calculated‚ next‚ these pairs of electrons are rearranged in order to minimize the repulsion between them. Different number of bonding pairs and lone pairs of electrons can form different structure. When there are only two bonding pairs around the central atom‚ for instance‚ the
