Attention chemistry students! If your chemistry class is eating your lunch, you need to see, learn and put in action the "10 Commandments of Chemistry" ;.
Chemistry 10 Commandments
#1 Thou shall remember both of these basic ideas.
You'll need to remember two quite 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 need to become very familiar having its layout. You should know what the periods and groups (families) mean. You should know how the periodic table is made to represent quantum mechanics and electron configurations. Take a moment and get to know the periodic table.
#3 Thou shall know the Polyatomic ions.
If you intend to have the ability to name compounds, write formulas and solve chemical equations you need to find out and understand polyatomic ions. One of the greatest methods for learning the polyatomic ions is flashcards.
#4 Thou shall know how to write electron configurations.
Even although you don't discover ways to use quantum numbers, you need to discover ways to write electron configurations. CAS 174063-87-7 Understanding electron configurations helps with Lewis dot symbols, valence electrons and chemical bonding.
#5 Thou shall know how to draw Lewis dot symbols.
Learn 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 intend to understand how chemical bonding works the know the octet rule. The tendency of an atom is to get rid of 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 could have a poor charge, but when it loses electrons it could have a positive charge. Know the oxidation quantity of an element can be quite useful in determining how elements combine to create compounds.
#8 Thou shall know the quantum numbers.
You don't have to understand how quantum numbers were developed or learn the mathematics behind them. But, you do need to know energy, sub levels and orbitals in order to write electron configurations and Lewis dot symbols.
#9 Thou shall know how to write chemical formulas.
You'll need to discover ways 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 should take action in order to change. So, I invite you to sign up for a totally free e-course and find out about
