A ruby is a pink to blood-red gemstone, a variety of the mineral corundum (aluminium oxide). The red color is caused mainly by the presence of the element chromium.
It is not a chemical compound with fixed ratios of elements, it is essentially Al2O3 with some Al3+ replaced by Cr3+
What else can I help you with?
What can chromium combine with?
Chromium can combine with various elements to form different compounds. For example, it can combine with oxygen to form chromium oxide, with carbon to form chromium carbide, and with sulfur to form chromium sulfide. Additionally, chromium can also combine with other metals to form alloy compounds.
What is the relationship among atoms elements and molecules?
Atoms are the basic building blocks of matter, and they combine to form elements. Elements are composed of one type of atom and can be found on the periodic table. When atoms of different elements are chemically bonded together, they form molecules.
When elements combine to form compounds their properties do not change.?
False. Hydrogen and oxygen - both gases - combine to form water - a liquid.
Can yttrium combine with other elements?
Yes, yttrium can combine with other elements to form compounds. Yttrium is a transition metal in the periodic table and has a valence electron configuration that allows it to form chemical bonds with other elements. It can form various compounds, such as yttrium oxide (Y2O3) and yttrium chloride (YCl3).
How do two elements combine together?
Two elements combine together through a chemical reaction where their atoms interact with each other to form a compound. This can happen through sharing or transferring of electrons, resulting in the formation of chemical bonds between the atoms of the two elements. The properties of the new compound are different from the properties of the individual elements.
What do elements combine to form?
Elements combine to form compounds through chemical reactions. These compounds have different properties than their individual elements, resulting in a wide range of substances found in nature and synthesized in laboratories.
which of the following is NOT true about elements when they combine to form compounds a. atoms of elements combine to form moleculesb?
yeah it is
How are mineral formed by crystallization from magma?
As magma cools, elements combine to form minerals.
When two or more elements combine they form a?
compound is when two or more elements combine chemically
How do elements combine together?
Two elements combine together by sharing electrons to form a bond.
When masses combine to form elements with larger masses?
Atomic fusion occurs when masses combine to form elements with larger mass.
What group of elements combine with other elements to form salts?
Metals form salts.
How do the elements of a compound form?
Elements combine together by chemical bonding to form compounds.
Shared when elements combine to form a compound?
Electrons are shared when elements combine to form molecules. These are subatomic particles with a negative elementary electric charge.
One or more elements can combine to form a compound when elements form compounds?
Yes, it is correct.
What is formed when two or more elements combine?
When two or more elements combine, they form a compound. Compounds are composed of atoms of different elements bonded together in specific ratios.
What can chromium combine with?
Chromium can combine with various elements to form different compounds. For example, it can combine with oxygen to form chromium oxide, with carbon to form chromium carbide, and with sulfur to form chromium sulfide. Additionally, chromium can also combine with other metals to form alloy compounds.
