Chemical engineers have discovered that adding nickel atoms to silver catalysts could revolutionize the production of ethylene oxide by eliminating the need for toxic chlorine while maintaining ...

The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near each other. An electron from each atom feels the attraction from the other atom ...

For example, the atomic number of chlorine is 17. Every chlorine atom has 17 protons and 17 electrons. It has 17 positive charges and 17 negative charges, meaning that it is neutral overall.

But the logic of the periodic table also relies upon the number and organisation of electrons in an atom. Let’s take chlorine as an example. It is positioned in group 7 of the periodic table ...

chlorine is less reactive than fluorine because the outer electrons in a chlorine atom are further from the nucleus than the outer electrons in a fluorine atom. It is harder for a chlorine atom to ...

Scientists have discovered a potentially greener way to produce a crucial industrial chemical used to make many everyday ...

This symbol tells you that the chlorine atom has 17 protons. It will also have 17 electrons, because the number of protons and electrons in an atom is the same. The symbol also tells you that the ...
