Attention chemistry students! If your chemistry class is eating your lunch, you will need to read, learn and put 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 least energy (the easy way)
#2 Thou shall know the Periodic Table.
You don't need to memorize the periodic table to make use of it. But, you must become very familiar having its layout. You have to know what the periods and groups (families) mean. You have to know the way the periodic table is designed 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 want to be able to name compounds, write formulas and solve chemical equations you need to find out 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 learn to use quantum numbers, you will need to learn 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 want to understand 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 number of an atom is its possible charge. If the atom gains electrons then it may have a poor charge, but if it loses electrons it may have an optimistic charge. Know the oxidation number of an element can be quite 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. CAS NO.125248-71-7 But, you do need to understand energy levels, 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 learn to write chemical formulas to be able to write chemical equations effectively.
#10 Thou shall Practice, Practice and Practice.
None of those commandments are worthwhile in the event that you don't practice. You need to take action to be able to change. So, I invite you to register for a free of charge e-course and find out more about
