Is ALL organic compounds contains carbon BUT not all compounds with carbon are organic???

Crude starting materials can be divided into different pure substance

Who Made the Quantum Mechanical Model

Who discovered electron

What is the principle that states, “Electrons in an atom occupy first the lowest possible energy levels and/or orbitals?”

• Bohr's Principle

• Heisenberg's Uncertainty Principle

• Aufbau (Building-Up) Principle

• Pauli's Exclusion Principle

According to which rule, electrons in an atom fill orbitals of the same energy level one by one before pairing up?

• Hund's Rule

• Pauli's Exclusion Principle

• Heisenberg's Uncertainty Principle

• Bohr's Rule

Which principle states that an atom tends to gain, lose, or share electrons in order to have a full set of valence electrons?

• Octet Rule

• Aufbau (Building-Up) Principle

• Hund's Rule

• Pauli's Exclusion Principle

Modified scanning electron microscope

Employ the use of scanning tunneling microscope in order to have a picture of an atom

study of matter, its composition, properties and the change

it undergoes.
