Attention chemistry students! If your chemistry class is eating your lunch, you need to read, learn and placed into action the "10 Commandments of Chemistry" ;.
Chemistry 10 Commandments
#1 Thou shall remember these two basic ideas.
You'll need to keep in mind two very simple ideas:
- opposites attract and likes repel
- nature moves toward the smallest amount of energy (the easy way)
#2 Thou shall know the Periodic Table.
You don't need to memorize the periodic table to utilize it. But, you need to become very familiar using its layout. You should know what the periods and groups (families) mean. You should know how a periodic table was created to represent quantum mechanics and electron configurations. Take some time and get to know the periodic table.
#3 Thou shall know the Polyatomic ions.
If you wish to have the ability to name compounds, write formulas and solve chemical equations you need to know and understand polyatomic ions. One of the finest methods for learning the polyatomic ions is flashcards.
#4 Thou shall learn how to write electron configurations.
Even though you don't learn to use quantum numbers, you need to learn to write electron configurations. RM257 Understanding electron configurations helps with Lewis dot symbols, valence electrons and chemical bonding.
#5 Thou shall learn how to draw Lewis dot symbols.
Learn how to draw Lewis dot (electron dot) symbols to simply help with understanding valence electrons and chemical bonding.
#6 Thou shall know the octet rule.
If you wish to understand how chemical bonding works the know the octet rule. The tendency of an atom is to reduce or gain electrons in order 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 will have a negative charge, but when it loses electrons it will have a confident 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 need to understand how quantum numbers were developed or learn the mathematics behind them. But, you do need to comprehend energy levels, sub levels and orbitals so you can write electron configurations and Lewis dot symbols.
#9 Thou shall learn how to write chemical formulas.
You'll need to learn to write chemical formulas in order to write chemical equations effectively.
#10 Thou shall Practice, Practice and Practice.
None of the commandments are a bit of good in the event that you don't practice. You have to take action in order to change. So, I invite one to register for a free e-course and learn more about
