Vanadium is a metal that has an atomic mass of 50.9414 g.mol 1 and an atomic number of 23. It is a soft white substance that can be found with many different minerals. Vanadium has 4 energy levels‚ the first energy level contains two protons‚ the second contains 8 protons‚ the third contains 11 protons and the fourth contains 2 protons. Vanadium is a metal that is commonly found in jet engines‚ high speed airframes‚ and ferrovanadium‚ a steel additive. Vanadium is toxic to humans and animals. Vanadium

Isotopes in Agriculture An isotope is a two or more atom that has different mass number but the same atomic number. An isotope is a variation of an element with a difference in the normal number of neutrons. The increased mass of an isotope can cause the chemical reactions they are used in to progress more slowly than a reaction that does not use isotopes. Not all isotopes are radioactive and there are many uses for them. They can be used in medicine‚ diagnose‚ nutrition‚ agriculture‚ research

Question: “It is more important to discover new ways of thinking about what is already known than to discover new data or facts. To what extent would you agree with this claim?” According to the Miriam-Webster dictionary‚ data can be defined as factual information used as basis for reasoning‚ discussion‚ or calculation. By the same dictionary‚ fact is defined as a piece of information presented as having objective reality. In this essay‚ it is vital to distinguish that the issue the question

Beryllium Atomic Symbol:Be Atomic number:4 Atomic Mass:9.012182 g History Of Beryllium In early Ancient Civilizations‚ the substances of emerald and beryl were first recognized as the same substances. but in late 1798‚ French chemist Louis-Nicholas Vauquelin found out that the unknown element in the two substances was known as beryllium. Beryllium is obtained from the substances beryl and bertrandite by using chemical processes.(1) The first metal form was produced by Wohler and Bussy in 1828.

Experiment 5: VARIATIONS IN PROPERTIES IN THE THIRD ROW OF THE PERIODIC TABLE INTRODUCTION The periodic table is a tabular display of the chemical elements‚ organized on the basis of their atomic numbers and chemical properties. Elements are presented in increasing atomic number. Elements with the same number of valence electrons are kept together in groups‚ such as the halogens and the noble gases. Due to this‚ there are gaps that form four distinct rectangular areas or blocks. The f-block is not

BENIFICIAL AND ALTERNATIVELY NOT SO BENIFICAL USES OF RADIATION BY: Sanwal Hayat What is radiation? Radiation is away in which energy moves from one place to another for example energy radiates away when a stone dropped in the water in circular waves while sound energy radiates from speakers mouth to listeners ear and heat energy radiates from sun to earth.

work of two young chemists‚ Brett Thornton and Shawn Burdette‚ whose 2010 article I have drawn heavily from. As in the case of many of the seven elements already surveyed‚ the view that Moseley’s experimental demonstration of the concept of atomic number resolved all issues in a categorical fashion is once again shown to be highly misleading. Early Claims for Element 85 The position of element 85 in the periodic table shows it to lie among the halogens. Not surprisingly‚ therefore‚ the early
