The element of Nickel is number 28 which means it has 28 electrons and 28 protons (this is the atomic number). The atomic mass of Nickel is 58.71 g.mol^-1 which means that there are 30.69334 neutrons since you subtract the number of protons from the atomic mass to get the number of neutrons. The electronegativity of Nickel is 1.8 on the Pauling scale; this is the tendency of Nickel to attract a bonding pair of electrons. The density of Nickel is 8.9 g.com^-3 at 20°C and the melting point is 1454

INTRODUCTION 1.1. Nickel Nickel is a chemical element with atomic number 28. It is denoted by the symbol ‘Ni’ and is one of the main constituent of meteorites. It was discovered in 1751‚ by Axel Fredrik in Sweden. It belongs to the transition metal group and is known for its hardness and ductility. Significant chemical reactivity is exhibited by pure Nickel. Nickel in its pure or low-alloy form is used in several fields as it is highly resistant to various reducing chemicals. Nickel when annealed exhibits

In this study‚ nickel-titanium surfaces are coated with phenolic thin films of tannic acid and pyrogallol with the purpose of studying their corrosion resistance in physiological environments. Three tests are performed: the open circuit potential test‚ potentiodynamic polarisation and potentiostatic electrochemical impedance spectroscopy. Polarisation measurements are scrutinized in order to gain knowledge concerning the kinetics of the cathodic and anodic reactions‚ while the open circuit and impedance
