How many unpaired electrons are in a cu2+ ion? Electron Pairing Atoms and ions consist of electrons that occupy orbitals somewhere around the nucleus of the atom. Orbitals are spaces around the nucleus that an electron has the greatest likelihood of occupying. Different orbitals have different ene...
How many valence electrons are in a neutral atom of argon? Neutral Atoms: A neutral atom is one that has an equal number of protons and electrons. The positive charge of the protons and the negative charge of the electrons will cancel each other out. In the case of argon, it has 1...
If element X has 52 protons, how many electrons does it have?If element X has 60 protons, how many electrons does it have?Oxygen, with an atomic number of 8, is a neutral atom and has an ___ electrons in the first electron shell and ___ electrons in the second elect...
These particles, made up of protons and neutrons, are large and can only travel a short distance -- in fact, they can be stopped with just a piece of paper or even your skin. However, inhalation or ingestion of alpha particles can be very dangerous. Once inside your body, alpha ...
As the exhaled air from the suspect flows past one side of the fuel cell, the platinum oxidizes any alcohol in the air to produce acetic acid, protons and electrons. The electrons flow through a wire from the platinum electrode. The wire is connected to an electrical-current meter and to ...
As the exhaled air from the suspect flows past one side of the fuel cell, the platinum oxidizes any alcohol in the air to produce acetic acid, protons and electrons. The electrons flow through a wire from the platinum electrode. The wire is connected to an electrical-current meter and to ...
At the positive terminal, the protons and electrons recombine with oxygen from the air in a chemical reaction that produces water. The water is given off from the exhaust pipe as water vapor or steam. This type of fuel cell is called a PEM (different people say this stands for polymer ...
At the cathode side, the protons, electrons, and oxygen combine to produce water.This video shows how the process works: For Earth Day 2020, Plug released a more in-depth presentation about fuel cells, how they work, and how they’re used – you can check it out here:What Are Fuel ...
As we learned in intro physics, everything is made up of atoms, and atoms are made up of protons, neutrons and electrons. Protons have a positive charge, neutrons have a neutral charge, and electrons have a negative charge. Note that the atoms themselves can carry a positive or a ...
How many neutrons are there in an atom that contains 3 protons and has an atomic weight of 5 amu? Sometimes the stomach stops producing HCl. What effect would this condition have on digestion? How about RBC count? How are excess potassium ions eliminated from the body?
