How Many Neutrons and Protons Can Get Along? Maybe 7,000Clara Moskowitz, SPACE.com
How Many Protons? The atomic number on the Periodic Table identifies the number of protons in any atom of that element. Copper, atomic number 29, has 29 protons. Finding the atomic number of an element reveals the number of protons.
The protons move through the lower portion of the fuel cell and combine with oxygen and the electrons on the other side to form water. The more alcohol that becomes oxidized, the greater the electrical current. A microprocessor measures the electrical current and calculates the BAC. Breath Tests...

If the Air Force were to rejoin the development of the space plane at a later date, it could use the vehicle to control space both offensively and defensively. Currently, there are many international agreements that have prohibited the deployment of such weapons into space. One such agreement ...
Local conditions: Clear, dark skies are a must. Real-time social media reports: Many aurora chasers post live updates on platforms like X (formerly Twitter). I have been fortunate enough to witness the northern lights throughout Norway and Sweden, but I have to say the most dramatic and co...
The protons get sucked across a ‘proton exchange membrane’ (PEM), while the electrons – unable to cross the PEM – get sent through a circuit, power the motor and come out the other end to combine with the oxygen in the air which has been passed through the cathode. H2 becomes to...
