Is sodium a metal nonmetal or metalloid?
sodium (Na), chemical element of the alkali metal group (Group 1 [Ia]) of the periodic table. Sodium is a very soft silvery-white metal. Sodium is the most common alkali metal and the sixth most abundant element on Earth, comprising 2.8 percent of Earth’s crust.
Why is sodium a reactive metal?
Sodium on the opposite side of the table has the opposite properties. Its single outer electron makes the metal highly reactive and ready to combine with others at the first opportunity – such as the moment the metal hits water.

What group is sodium?
Group 1A — The Alkali Metals. Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Why is sodium so reactive?
Teaching Tips. Here are some of the main ideas students should take away from this video: Sodium (Na) is an alkali metal; it is shiny and soft with a single electron in its outermost shell. Alkali metals are highly reactive because they readily lose their outermost electron.
What is the atomic number of the element sodium?
body-centered cubic (bcc) Sodium is a chemical element with the symbol Na (from Latin natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal.
Which is the most common compound of sodium?
The most common compound of sodium is sodium chloride (common salt). It is added to food and used to de-ice roads in winter. It is also used as a feedstock for the chemical industry. Sodium carbonate (washing soda) is also a useful sodium salt. It is used as a water softener.
Why is sodium important in the periodic table?
Sodium, like most elements in the periodic table could be said to have a dual personality. On one side it is an essential nutrient for most living things, and yet, due to its reactive nature is also capable of wreaking havoc if you happen to combine it with something you shouldn’t.
Where does most of the sodium in the diet come from?
Sodium chloride is the principal source of sodium in the diet, and is used as seasoning and preservative in such commodities as pickled preserves and jerky; for Americans, most sodium chloride comes from processed foods.
