For example, the atomic number of sodium is 11. Every sodium atom has 11 protons and 11 electrons. It has 11 positive charges and 11 negative charges. The mass number of an atom is its total ...

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 ...

A sodium atom has one electron in its outer shell. The atom is more stable if it has a full outer shell. A sodium atom can lose its outer electron. It will still have 11 positive protons but only ...

However, this has the problem that the sodium atom is larger than the lithium atom, making it more difficult to move when charging and discharging the battery. The research team solved this problem by ...

Many car airbag inflators contain small amounts of a toxic molecule called sodium azide, or NaN 3 (one sodium atom and three nitrogen atoms combined). Sodium azide breaks down very quickly when heated ...
