Protons and neutrons are the sub-atomic particles present in the nucleus of an atom where as electrons are present revolving round the nucleus in orbits. Electrons are negatively charged, protons are positively charged where as a neutron is a neutral species. It is the presence of electric charge that lead to the discovery of electrons (negative charge) and protons (positive charge), while it took time to discover neutral as they were electrically neutral species. Neutrons carrying no charge were not detected easily by passing electromagnetic radiations. Therefore, neutrons were the last of the three subatomic particles, to be discovered.
Where is chemical equation?
Answer:
TiCl2
Explanation:
Mass of the chloride of titanium= 1.31 g
Mass of titanium= 0.528 g
Therefore mass of chlorine = 1.31-0.528 = 0.782 g
To determine the empirical formulae of the titanium chloride, divide the mass of each element by its relative atomic mass and divide through by the lowest ratio.
Ti- 0.528/48 = 0.011, Cl- 0.782/35.5 = 0.022
Ti- 0.011/0.011 , Cl- 0.022/0.011
Ti- 1, Cl-2
Hence the required empirical formula is TiCl2
Kepler's first law explains that the sun is the focus of our solar system, and that A. <span>the orbit of a planet around the sun is an ellipse. Kepler proved that the orbit of the sun is an elliptical path and is used to derive the motion of the satellites and space vehicles today.</span>
Answer:
Nuclear fusion plays an important role in making elements that are heavier than helium.
Explanation:
Nucleosynthesis is the process by which new atomic nuclei are created from pre-existing nucleons (protons and neutrons) and nuclei. According to current theories, the first nuclei were formed a few minutes after the Big Bang, through nuclear reactions in a process called Big Bang nucleosynthesis.
In order to synthesize a new element, there must be a change in the number of protons. We should remember that elements are known by the number of their protons as it represents their atomic number.
Elements heavier than helium are formed by nuclear nucleosynthesis in which nuclear fusion plays a very crucial role as typified by the equations shown in the question.
