Sodium, this neutral atom with a loosely-held outermost electron, is now in the presence of water. This isn't just the neutral H2O molecules, but the hydroxyl ions and the individual protons.

Indeed, sodium chloride — each molecule consists of one sodium atom and one chlorine atom — is often thought of first as an antifreeze, lowering the freezing temperature of water.

The sodium atom (NA) and the water (H2O), combine to form NaOH, with a lot of hydrogen gas left over. The reaction releases a lot of heat, and the heat ignites the hydrogen gas.

Sodium azide is a white powder that explodes when it hits metal. When it hits water, it turns into an acid that can eat through your skin. When it’s inhaled, it shreds your lungs.

When an atom loses or gains an electron, it is called an ion. The atom that loses an electron becomes a positive ion. The atom that gains an electron becomes a negative ion. A positive and negative ...

How many of each type of atom are there in the compound sodium bicarbonate? There are one sodium atom, one hydrogen atom, one carbon atom, and three oxygen atoms in every unit of sodium bicarbonate.

Instead of water, they used a nanoscopic droplet of liquid helium cooled to -273°C as the solvent – and instead of a grain of salt, they used an atom of sodium. The researchers embedded a xenon ...

In the new, supercontrolled chemical reaction, researchers trapped a single sodium atom in one optical tweezer — a device that snares small particles in a laser beam — and a cesium atom in ...

MSG's name tells us the key difference between glutamate and monosodium glutamate. MSG has a sodium atom that glutamate doesn't, which turns it into a salt form, making it easy to add to food.
