a chemical previously unknown to science that is a compound of one chlorine atom, two nitrogen atoms, and two oxygen atoms. But the implications of the discovery are unclear. While it bears ...

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 ...

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 ...

A chlorine atom can react with ozone to form an oxygen molecule (O2) and a molecule of chlorine monoxide (ClO), and the chlorine atom is “regenerated” when the chlorine monoxide molecule reacts with ...

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 ...

The electrons in the covalent bond are shared equally between the two oxygen atoms. The chlorine atom has a higher electronegativity than the hydrogen atom, so the bonding electrons will be closer to ...

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.
