No, carbon dioxide is not the same as oxygen (O2). Carbon dioxide is a molecule composed of one carbon atom and two oxygen atoms (CO2). Oxygen, on the other hand, exists as O2, where two oxygen atoms are bonded together.
When all atoms are the same, it forms a chemical element. Each element is characterized by a unique number of protons in its nucleus, which determines its chemical properties. Examples of elements include oxygen, carbon, and hydrogen.
The smallest part of carbon with all the same properties is called an atom. Carbon atoms are the building blocks of all carbon-based materials and have the same chemical properties regardless of their arrangement in a molecule.
In two CO2 molecules, there are two types of atoms present: carbon (C) and oxygen (O). Each CO2 molecule contains one carbon atom and two oxygen atoms, so in total, there are 2 carbon atoms and 4 oxygen atoms in 2 CO2 molecules. However, the types of atoms remain the same—just carbon and oxygen.
The atoms are different sizes.
The physical properties are unchanged: the same melting or boiling point, resistivity,density etc.But these atoms are now bonded together.
No. They are two different atoms with different amounts of electrons
No, a compound of one hydrogen atom and two oxygen atoms (H2O2, hydrogen peroxide) does not have the same properties as a compound of two hydrogen atoms and two oxygen atoms (H2O, water). Hydrogen peroxide is a reactive oxidizing agent with strong bleaching and disinfecting properties, while water is essential for life and has very different chemical and physical properties. The arrangement and ratio of atoms in a compound significantly influence its characteristics and behavior.
They have same atomic number, 6 that means same number of protons and electrons so have the same chemical properties.
Atoms do have the same properties as long as stable form of its corresponding element is not a molecule. For example H1 (Hydrogen) which is a single atom has the same properties that of Hydrogen as it doesn't require to be in a molecular form to be stable. On the other hand O1 (Oxygen) doesn't have the same properties as Oxygen that we breathe as that Oxygen is actually O2 which is actually necessary for it to remain stable.
If you mean CO2 there are 3 atoms of two elements: 1 carbon atom and 2 oxygen atoms. If you really did mean Co2, that would be a diatomic molecule of cobalt containing 2 atoms of 1 element. However, no such molecule exists.
Yes, a sample of carbon dioxide in your school and another sample in Australia would have the same composition since carbon dioxide is made up of one carbon atom and two oxygen atoms. They would exhibit similar properties such as being colorless, odorless, and non-flammable under normal conditions.
