At 14–16, students will learn about patterns of reactivity and will use the periodic table to determine the number of shells and electrons in an atom. Students will also learn about the development of the atomic model, which has parallels in the scientific processes used by Mendeleev and others.
Q. What did Greek thinkers do?
In ancient Greece, philosophers contemplated and theorized about many different ideas such as human nature, ethics, and moral dilemmas. Ancient Greek philosophers can be categorized into three groups: the Pre-Socratics, the Socratics, and the Post-Socratics.

Q. What did ancient Greek thinkers emphasize?
Ancient Greek thinkers emphasized what? People should observe the world carefully and draw logical conclusions about what they see.
Q. Who was responsible for the development of the periodic table?
British chemist John Newlands was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves.
Q. Do you have to memorize the periodic table?
No, you don’t need to memorize the periodic table, except for pulling freak memory stunts. But knowing a lot of the properties and how they vary over the periodic system will really help you make connections and will make you think chemistry a lot faster.
Q. What is the trick to memorizing?
Use mnemonics. Mnemonics are systems and tricks that make information for memorable. One common type is when the first letter of each word in a sentence is also the first letter of each word in a list that needs to be memorized.
