An element reacts with another element by sharing electrons. The elements keep sharing electrons until both elements have a full outer shell.
Measure of its chemical reactivity.
For example halogens and sulfur reacts with silver.
Magnesium on heating reacts with oxygen and halogens but it also reacts with nitrogen.
Yes, rubidium has many chemical compounds.
The reaction of oxygen with other elements is oxidation. An example is iron and oxygen reacting to form rust.
Ba looses its two electrons to form Ba 2+ ion and then it reacts with other elements to form compounds.
Potassium does not react at all with some elements such as helium, but when it reacts, it always forms a positive ion.
Any element in column 1 of a wide form periodic table has exactly one valence electron and reacts with other elements.
It barely reacts with other elements, just like gold. That is why it is considered a rare element.
Alkaline earth metals
Measure of its chemical reactivity.
No, potassium is an extremely reactive metal that reacts very easily with other elements.
I reacts in order to get a filled valence shell of electrons.
For example halogens and sulfur reacts with silver.
Li mainly reacts with other elements by donating it's one lone valence electron to become Li+ and then it forms an ionic bond. For example, Li reacts with Cl by donating an electron and making LiCl.
Magnesium on heating reacts with oxygen and halogens but it also reacts with nitrogen.
Chlorine is reactive and can form compounds with many other elements. It commonly reacts with metals to form metal chlorides, and with nonmetals to form covalent compounds. Its reactivity makes it an important component in a variety of chemical processes and products.
