Why is radium called an element and not a chemical compound?
Radium is a chemical element; a compound has a minimum of two chemical elements.
What is a material that contains three elements joined in a fixed proportion?
If a material contains three elements joined in a fixed proportion, then it is a compound. It can only be separated by a chemical reaction.
What is the little number immediately to the right of each elements in a compound?
The little number immediately to the right of each element in a compound is called a subscript. It indicates the number of atoms of that element present in the compound.
What is compound composed of molecules called?
A chemical compound is composed of two or more different chemical elements bonded together, most commonly through ionic or covalent bonds. In a covalent bond, the elements "share" electrons, while in ionic bonds, one element "takes" electrons from the other element. The bonds are usually performed to neutralize electronic charges, and the resulting attracting forces holds the elements together.
Do each element contains at least two atoms?
Every element in the periodic table contains at least two atoms joined up except for Hydrogen (H).
Why is radium called an element and not a chemical compound?
Radium is a chemical element; a compound has a minimum of two chemical elements.
Is hydrogen sulfide an element or a compound?
H2SO4 is a compound called sulphuric acid. An element is made up of one element, a compound is made up of different elements stuck together. A mixture is elements and or compounds together but not bonded.
What Elements contain only one type of atom?
Elements that contain only one type of atom are called pure elements or monatomic elements. For example, helium (He), neon (Ne), and oxygen (O) are pure elements because they consist of only one type of atom in their chemical structure.
What is a material that contains three elements joined in a fixed proportion?
If a material contains three elements joined in a fixed proportion, then it is a compound. It can only be separated by a chemical reaction.
Is the element He a compound?
NO!!!! He (Helium) is monatomic gas, that is it exists as single atoms, and does NOT combine with any other substance to form a compound. 'He' is the most inert element of all. It alsao has the lowest condensing point 4K4 (-269 oC) and freezing point at 2K (-271oC).
Why Elements are aleways combined in a compound with another element why does this occur?
That's because of the way "compound" is defined. If atoms of an element combine with other atoms of the SAME element, then it's not called a "compound".
What is the process called when a compound is made directly from the element in it?
Its called a compound. When 2 elements come together they will sometimes be able to form a compound. a compound is 2 elements formed together to make 1 single substance.
What is the name of the element MgI2?
MgI2 is not an element, it is a compound of the two elements magnesium, and iodine.It is called magnesium iodide.
What type of reaction can an element and compound be combined?
An element and a compound can undergo a chemical reaction called a single replacement reaction. In this type of reaction, the element replaces one of the elements in the compound, forming a new compound and a different element as a product.
Is thallium a element or a compound?
element. But most elements can also be compounds. For example, oxygen is the name of an element, but two oxygens bonded together are also called oxygen, and are a compound.
Pure substances made from only one type of atom are?
This would be called an element, or a mono-atomic compound.
Is MgO a ionic compound?
No. MgO is a compound called magnesium oxide. It is composed of two elements: magnesium and oxygen.Hint: if the chemical formula contains more than one capital latter than the substance is not an element.
