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 ...

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 ...

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 ...

It's made up of a central nucleus consisting of protons and neutrons, called nucleons, with electrons orbiting around the ...

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 ...

In simple terms, that assertion is correct, but for those with an expertise in the field, the longer answer to who did it ...

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 ...

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 ...

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 ...

If a gas is subjected to very high temperatures, it becomes a plasma. In plasma, electrons are stripped from the atoms. An atom with no electrons orbiting around the nucleus is said to be ionized and ...

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 ...
