If a molecule is made of only one type of atom, then it is a pure element in molecular form. For example, hydrogen gas, as it was used in balloons before the Hindenburg caught fire, is a pure element. That gas consists of hydrogen molecules - H2. Hydrogen gas nearly always forms two-atom molecules and is still a pure element.
The Oxygen in the air is a pure element but it also is only found as two-atom gas-molecules - O2.
The well-known Buckyballs which are large molecules of carbon are nothing but carbon and therefore are molecules of one element - pure carbon.
What else can I help you with?
Why is yogurt not a pure substance?
Yogurt is not a pure substance because its a mixture of different elements/molecules (Cow milk and sugar and more...) from the Periodic Table
Are all elements pure?
No, they can contain impurities.
Many elements found in nature exist as?
The chemical substances found in the atmosphere exist as gases.
How many atoms are in a raindrop?
Each pure water drop is composed of only two elements: hydrogen and oxygen. Most drinking water is composed of other compounds or elements to make it cleaner and safer to drink.
Which elements on the periodic table are pure?
Well technically, they're all pure in their pure form. haha, The question doesn't really make sence. You should look up what an element means. An element is just a category that an atom may fall into. The question of purity can't be asked about an element. You can ask "is this sample of matter of the element (blank) pure?" But not about the element itself
What is a name for elements and compounds?
Elements and compounds are pure substances. They also can be molecules.
What matter is made of something that combine to form molecules?
Pure elements are combined together to form molecules.
Are molecules and elements the same thing?
No, molecules and elements are not the same thing. An element is a pure substance made of only one type of atom, while a molecule is a group of atoms bonded together. Elements can exist as single atoms or as molecules depending on their chemical composition.
Why is yogurt not a pure substance?
Yogurt is not a pure substance because its a mixture of different elements/molecules (Cow milk and sugar and more...) from the Periodic Table
Are elements and compounds made of atom?
Yes. Elements are composed of individual atoms. Compounds are composed of molecules, which are chemical combinations of atoms. Some pure elements exist as molecules containing various numbers of combined atoms, such as atmospheric oxygen (O2) and ozone (O3).
Are elements and compounds are made of atoms?
Yes. Elements are composed of individual atoms. Compounds are composed of molecules, which are chemical combinations of atoms. Some pure elements exist as molecules containing various numbers of combined atoms, such as atmospheric oxygen (O2) and ozone (O3).
How are molecules, compounds, and pure substances related in terms of their chemical composition and properties?
Molecules are the smallest units of compounds, which are made up of two or more different elements chemically bonded together. Pure substances can be either elements or compounds. All three are related in that they have specific chemical compositions and properties that are unique to their structure.
Do pure substances have identical or diffrent particles?
Pure substances have identical particles. This means that all samples of a pure substance will have the same type and arrangement of particles, whether they are atoms, molecules, or ions. Examples of pure substances include elements and compounds.
Of pure substances diatomics are elements or compounds?
They are molecules composed of two atoms of the same element.
What are 3 pure elements that are mixtures?
Pure elements cannot be mixtures.
What are the pure elements on the periodic table?
All the elements from the periodic table can be obtained as pure elements.
A pure substance is either a compound or?
The components of a pure substance can be either molecules or atoms.
