On the periodic table you can decide whether it's a metal, metalloid or nonmetal (excluding transition metals). constantly proportionality constant, and that's equal to nine times 10. In one particular collision between an anti-helium nucleus and a helium nucleus, the nuclei are Helium is composed of two electrons in atomic orbitals surrounding a nucleus containing two protons and (usually) two neutrons. The helium-6 nucleus is a proving ground for nuclear physicists probing . (a) Explain how this observation led scientists to the idea that it is possible to convert hydrogen into helium to produce thermal energy. For example, an electrically neutral helium atom has an atomic number This means it has two electrons orbiting the nucleus with a charge of When one of the orbiting electrons is removed from the helium atom (we say, when the helium atom is singly ionized), what remains is a hydrogen-like atomic structure where the remaining electron orbits the . . This works because, in general, the ion charge is not important in the balancing of nuclear equations. 0.
