- Explain why Be and Mg form metallic hydrides instead of ionic hydrides like the other elements in Groups 1 and 2?If the left most element in a period combined with each of the others in the period, how would the type of bonding change from left to right? Explain in terms of atomic properties.Explain the term "electron sea" in terms of metallic bonding and use it explain one of the properties (such as malleability or conductivity) of a metal such as copper.
- The atomic radius of elements decreases along the period but Neon has highest size among III period element? WhyWhich element does NOT exhibit paramagnetism?Chromium, manganese, and barium are all examples of metals that can be prepared in a pure form by combining oxides of theses elements with reactive metals. When aluminum is chosen as the reactive metal, the process is referred to as the Goldschmidt process or the Thermite process. a.) What type of reaction is the Goldschmidt process? b.) Write the formulas for the common oxides formed by chromium, manganese, and barium. c.) Predict the products formed by each of the three oxides in the Goldschmidt process, using a balanced chemical equation.
