metals. Non-metals are brittle and shatter when hit. Non-metals are poor conductors of electricity and heat. Non-metals melt at low temperatures. Metalloids are elements that have the properties of both metals and non-metals. Metallic lustre is a shine emitted from smooth metallic surfaces. Electrons are negatively charged particles that orbit the nucleus. Protons are positively charged particles found in the nucleus that determine the atomic number of the element and the number of electrons can carry

bonding‚ atoms lose‚ gain‚ or share electrons in order to have the same number of electrons as the noble gas that’s nearest on the periodic table. Ionic‚ covalent‚ and metallic bonds are formed by combinations of metals and nonmetals. * Metal + nonmetal = ionic bond * Nonmetal + nonmetal = covalent bond * Metal + metal = metallic bond When two elements engage in ionic bonding‚ one or more electrons are transferred from the metal to the nonmetal‚ forming ions (charged atoms). The metal‚ having

temperatures were reached‚ heavy metallic elements sank to the planet’s center of gravity‚ as lighter elements were displaced upward toward the surface. This process may have taken place in as little as 50 million years. It is fairly certain that the present core-mantle-crust structure was in place by 4 billion years ago. Earth’s core consists of both solid and liquid metal‚ presumably of nickel-iron composition. The outer‚ liquid metallic core revolves around the inner‚ solid metallic core and‚ in the process

metals are elements of group 2 in the periodic table‚ so they have 2 electrons in outermost energy level. So to become stable they will try to lose 2 electrons to have a stable electron configuration. So they all have +2 oxidation states. 5. The metallic character of alkaline earth metals increases as you go down the group because the further down the group you go‚ the less ionization energy there is. The less ionization energy there

both vernier and micrometer calipers accurately on measuring provided materials. The objectives of the act were to familiarize the students with the use of the said scales and to demonstrate their differences. The dimensions of a metallic cube made of steel and a metallic washer were measured using a vernier caliper while that of a marble made of glass and the same metal cube were measured using the micrometer caliper. The density and percentage error of each material were then computed using the
