The (n + l) rule, also known as the Aufbau principle, is a guideline used to determine the order of electron filling in atomic orbitals. It states that electrons occupy orbitals in order of increasing values of the sum of the principal quantum number (n) and the azimuthal quantum number (l). For example, the 3s orbital (n=3, l=0) has a value of 3, while the 4s orbital (n=4, l=0) has a value of 4, so the 3s fills before the 4s. Similarly, the 3p orbital (n=3, l=1) has a value of 4, making it fill after the 4s but before the 3d orbital (n=3, l=2), which has a value of 5.

What is octet rule and give two examples which do not follow this rule?
The octet rule is a rule in chemistry where elements want to form bonds to attain 8 electrons in their valence shell. An example of this would be sodium chloride. Bonds that don't have 8 electrons in their valence shell don't follow this rule
In the scientific theory what can you think of as a rule of nature?
In scientific theory, a rule of nature is a fundamental principle that describes how the natural world behaves consistently under certain conditions. These rules are based on observations, experimentation, and mathematical models that help explain and predict natural phenomena. Examples of rules of nature include Newton's laws of motion, the law of gravity, and the laws of thermodynamics.
What style of authoritarian rule specifically involves claiming a god-given right to rule?
Divine right is the style of authoritarian rule that specifically involves claiming a god-given right to rule.
What is the rule of nature that tells you what will happen under certain conditions?
The rule of nature that governs what will happen under certain conditions is known as cause and effect. This principle states that every action has a reaction, and events are interconnected through a chain of cause-and-effect relationships. By understanding this rule, we can predict and explain outcomes based on the circumstances that precede them.
What is huckel rule?
In 1931, German chemist and physicist Erich Hückel proposed a theory to help determine if a planar ring molecule would have aromatic properties. His rule states that if a cyclic, planar molecule has 4n+2 π electrons, it is considered aromatic.

How do you factor x3 plus 7x2 plus 18x plus 24?
I know the answer is x(x^2+3x+6) + 4(x^2+3x+6) which factors to (x+4)(x^2+3x+6) but I don't know the rule behind this. Could someone explain it to me?
