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.
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 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.
Divine right is the style of authoritarian rule that specifically involves claiming a god-given right to rule.
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.
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.
Ha i recently wondered this! There is no answer a positive plus a positive always equals a negative (vice versus) its just the mathematic rule!
There's a rule?
A general rule used to explain a specific event is called?
explain how to find the rule in a numerical pattern
Not clear if this is about the word ‘rule’, or about something called the word rule.

rule that could explain what makes a sentence grammatically correct or not before the noun."
yes they do follow the rule of law.

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?
