Answer:
Yes
Explanation:
Atoms are generally classified as pure substances. A pure substance has the following properties:
- All parts are the same throughout i.e. homogeneous
- They have definite composition
- The cannot easily be broken down into simpler substances by physical means.
- Separation by physical methods is not easy.
- They have unique sets of physical properties.
Elements and compounds are generally classified as pure substances. Since atoms are the building blocks of pure substances, they can be classified as one.
I need a question to answer lol

Answer:
D: Protons that make up a nitrogen atom stays together in the nucleus
This is because a electromagnetic force is responsible for atomic structure, chemical reactions, the attractive and repulsive forces associated with electrical charge and magnetism, and other electromagnetic phenomena.
The delocalized cloud of π electrons in benzene is formed by the overlap of 6<u> p-orbitals</u>.
So, option B is correct one.
In the case of hydrocarbons, delocalisation occurs in benzene rings , where a hexagon of six carbon atoms has decalized electrons spread over the whole ring.
All of the carbon atoms in the benzene rings are 
orbitals around the ring produces a framework of six sigma bonds, while the unhybridized p-orbitals which are perpendicular to this plane over in side-to-side fashion to form three pi-bonds.
