Oxygen only has 6 outer electrons and wants to get to a stable 8. Argon already has a stable 8 outer electrons
Yes, hydrogen is reactive because it readily combines with other elements to form compounds.
Yes, it can, and it combines with many other elements. The most common example is sodium chloride, ordinary table salt.
One chemical property of oxygen is its ability to react with other elements to form oxides. Oxygen is a highly reactive element that readily combines with many other elements, such as iron (Fe) to form iron oxide (Fe2O3) or hydrogen (H) to form water (H2O).
A gas, also very lightweight.
The ease and speed in which an element combines or reacts with other substances is called reactivity. Reactivity is a measure of how readily an element undergoes a chemical reaction.
Group 17 or halogens will combine readily with group 1 elements.
Yes, hydrogen is reactive because it readily combines with other elements to form compounds.
sodium
Yes, copper readily combines with several other elements. Combined with zinc it is brass, combined with tin it is bronze. It combines with many other elements including oxygen and sulfur.
Groups 1 and 17.
Alkaline Earth metals
Oxygen is the most reactive gas in the atmosphere. It readily combines with other elements and compounds to form oxides.
It has very little impact. It accounts for only 0.00001% of the atmosphere and, being inert, it does not readily react with other elements (or compounds)
Group 1 metals, such as sodium and potassium, readily combine with group 17 elements (halogens) to form salts. These metals have one electron in their outermost shell, which they can easily lose to achieve a stable electron configuration, while halogens are one electron short of a stable configuration and readily accept an electron to form a stable ion.
Hemoglobin combines readily with oxygen.
reactivity
Barium can form compounds with many elements, including oxygen, sulfur, and halogens like chlorine. Barium also readily combines with metals such as aluminum or magnesium to form alloys. However, some combinations with specific elements may not be stable or practical.
