When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...
It's made up of a central nucleus consisting of protons and neutrons, called nucleons, with electrons orbiting around the ...
British philosopher Bertrand Russell said of the difference between our physical world experience and the scientific world of continually changing matter, “There is … some conflict between what common ...
Players read questions about energy levels and score points by picking the correct element as the answer. Electrons are in regions around the nucleus that are different distances away from the nucleus ...
They have a radius of around 1 × 10 10 metres ... chlorine also has 17 electrons. The relative mass of a nucleus is the number of protons and neutrons it contains. Because the mass of a proton ...
Since electrons have almost no mass, it seemed that something besides the protons in the nucleus were adding to the mass. One leading explanation was that there were electrons and additional ...
Important material properties can be explained at the level of quantum physics - for example, whether a material conducts electricity or not. Analysing such quantum states has now revealed that there ...
All of the negative charge was held in the electrons, which must orbit the dense nucleus like planets around the sun. In 1912 Bohr joined Rutherford. He realized that Rutherford's model wasn't ...
negatively charged electrons on the innermost shells are pulled in closer to the nucleus, more than they are in silver. This close to the atom, in order to not fall into it, they must zip around ...
It’s made up of a central nucleus consisting of protons and neutrons, called nucleons, with electrons orbiting around the nucleus. Nobel prize-winning physicist Niels Bohr described these ...
