Attention chemistry students! If your chemistry class is eating your lunch, you need to learn, learn and put into action the "10 Commandments of Chemistry" ;.
Chemistry 10 Commandments
#1 Thou shall remember those two basic ideas.
You'll need to consider two very simple ideas:
- opposites attract and likes repel
- nature moves toward the least energy (the easy way)
#2 Thou shall know the Periodic Table.
You don't have to memorize the periodic table to utilize it. But, you must become very familiar having its layout. CAS 174063-87-7 You need to know what the periods and groups (families) mean. You need to know how the periodic table was created to represent quantum mechanics and electron configurations. Take the time and get to learn the periodic table.
#3 Thou shall know the Polyatomic ions.
If you intend to be able to name compounds, write formulas and solve chemical equations you have to know and understand polyatomic ions. One of the finest methods for learning the polyatomic ions is flashcards.
#4 Thou shall understand how to write electron configurations.
Even if you don't discover ways to use quantum numbers, you need to discover ways to write electron configurations. Understanding electron configurations helps with Lewis dot symbols, valence electrons and chemical bonding.
#5 Thou shall understand how to draw Lewis dot symbols.
Learn to draw Lewis dot (electron dot) symbols to greatly help with understanding valence electrons and chemical bonding.
#6 Thou shall know the octet rule.
If you intend to know how chemical bonding works the know the octet rule. The tendency of an atom is to reduce or gain electrons to be able to obtain a Noble gas valence.
#7 Thou shall know oxidation numbers.
The oxidation quantity of an atom is its possible charge. If the atom gains electrons then it can have a negative charge, but when it loses electrons it can have a positive charge. Know the oxidation quantity of an element can be extremely useful in determining how elements combine to make compounds.
#8 Thou shall know the quantum numbers.
You don't have to know how quantum numbers were developed or learn the mathematics behind them. But, you do need to comprehend energy, sub levels and orbitals in order to write electron configurations and Lewis dot symbols.
#9 Thou shall understand how to write chemical formulas.
You'll need to discover ways to write chemical formulas to be able to write chemical equations effectively.
#10 Thou shall Practice, Practice and Practice.
None of the commandments are any good if you don't practice. You need to take action to be able to change. So, I invite you to register for a totally free e-course and find out about
