Is a pure substance composed of only one type of atom or molecule?

Is a pure substance composed of only one type of atom or molecule?

A pure substance is composed of only one type of atom or molecule; a mixture is a substance composed of two or more different types of atoms or molecules. What is the difference between an element and a compound? A. A compound is a pure substance which cannot be decomposed into simpler substances.

What kind of matter is made up of only one particle?

Pure substances consist of only one type of matter. A pure substance can be an element, which consists of only one type of atom and cannot be broken down by a chemical change, or a compound, which consists of two or more types of atoms.

Can a single atom be considered a molecule?

A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Atoms and complexes connected by non-covalent interactions, such as hydrogen bonds or ionic bonds, are typically not considered single molecules.

What substance is composed of only one kind of atom ABCD?

element
Any substance that contains only one kind of an atom is known as an element. Because atoms cannot be created or destroyed in a chemical reaction, elements such as phosphorus (P4) or sulfur (S8) cannot be broken down into simpler substances by these reactions.

What are matter waves in chemistry?

Matter waves: According to De-Broglie, a wave is associated with each moving particle which is called matter waves. This wave has wave length λ=hpλ=hp. Here h is Planck’s constant and p is the moment of the moving particle.

What is matter that has only one kind of atom called?

Matter that has only one kind of atom is called an? Matter with only one particular kind of atom is known as an element. These atoms can either be located individually or combined into larger units. An example of this would be the notion that carbon is an element, because at it’s pure substance state it’s composed of only carbon atoms.

What is an element in chemistry?

Matter with only one particular kind of atom is known as an element. These atoms can either be located individually or combined into larger units. An example of this would be the notion that carbon is an element, because at it’s pure substance state it’s composed of only carbon atoms.

What is matter made up of?

Matter is composed of elements, compounds, and mixtures of the two Matter is made of mixtures and pure substances Pure substances are made of either pure compounds or pure elements Pure substances are made of either pure compounds or pure elements A compound is a ~ substance that contains two or more elements combined in a fixed proportion
