Chromium reacts directly with fluorine, F2, at 400°C and 200-300 atmospheres to form chromium(VI) fluoride, CrF6.
Cr(s) + 3F2(g) → CrF6(s) [yellow]
Under milder conditions, chromium(V) fluoride, CrF5, is formed.
2Cr(s) + 5F2(g) → 2CrF5(s) [red]
Under still milder conditions, chromium metal reacts with the halogens fluorine, F2, chlorine, Cl2, bromine, Br2, and iodine, I2, to form the corresponding trihalides chromium(III) fluoride, CrF3, chromium(III) chloride, CrCl3, chromium(III) bromide, CrBr3, or chromium(III) iodide, CrI3.
2Cr(s) + 3F2(g) → 2CrF3(s) [green]
2Cr(s) + 3Cl2(g) → 2CrCl3(s) [red-violet]
2Cr(s) + 3Br2(g) → 2CrBr3(s) [very dark green]
2Cr(s) + 3I2(g) → 2CrI3(s) [very dark green]
What else can I help you with?
An element's ability to react with oxygen is an example of what?
An element's ability to react with oxygen is an example of a chemical property. This property describes how elements interact with other substances to form new compounds. In this case, the element's reactivity with oxygen shows its tendency to form oxides.
Element reacts with almost every element?
Oxygen is an element that readily reacts with almost every other element due to its high electronegativity. It forms oxides with most elements, contributing to its strong reactivity.
What fourth period representative element has similar properties to oxygen?
Sulfur is a fourth period representative element that has similar properties to oxygen. Both elements belong to group 16 of the periodic table, also known as the oxygen group, and have similar chemical reactivity.
Is oxygen's reactivity high or low?
Oxygen stays as diatomic molecules in the atmosphere. These 2 oxygen atoms are bond with a double bond. So reactivity of oxygen is low.
A substance that has a high reactivity?
Potassium is an example of a substance with high reactivity due to its tendency to readily react with water or oxygen. This reactivity is due to its outer electron configuration, which makes it highly reactive in forming bonds with other elements.
What is the reactivity of an element?
Reactivity is a term related to the aggressiveness (or not) of an element to combine with other elements. Oxygen, Chlorine, and Fluorine are among the most aggressive.
What has the author William Brian Jennings written?
William Brian Jennings has written: 'Conformation and reactivity of tricarbonyl (arene) chromiums'
What is chromiums atomic mass?
Chromium is a metal element. Atomic mass of it is 51.996.

What is the most abundant element in the earth?
The most abundant element on earth is Oxygen. But due to its high reactivity, most oxygen occurs in combined state, generally in oxides.
Is the ease and speed with which an element combines with other substances?
Reactivity refers to the ease and speed with which an element combines with other substances. Factors like the number of electrons in the outermost energy level and electronegativity influence an element's reactivity. Highly reactive elements easily form bonds with other substances to achieve a stable electron configuration.
What element is most like oxygen?
Sulfur is an element that is most like oxygen in terms of its chemical properties. Both oxygen and sulfur belong to the same chemical group on the periodic table (Group 16), which means they have similar reactivity and can form compounds with similar characteristics.
What is formed when an element is burned in air or oxygen?
When an element is burned in air or oxygen, it forms oxides. The type of oxide formed depends on the reactivity of the element with oxygen. For example, carbon forms carbon dioxide while magnesium forms magnesium oxide.
