Essay about Periodic Table

The Periodic Table and Periodic Trends Introduction Periodic trends are plans that appear within the occasional table that lay out different viewpoints of a certain component, tallying its gauge and its electronic properties. Major occasional patterns incorporate electro-negativity, ionization imperativeness, electron enjoying, atomic clear, dissolving point, metallic character, and ionic clear. Intermittent patterns, developing from the course of activity of the irregular table, allow chemists with an invaluable gadget to quickly expect an element’s properties. These designs exist since of...

The History Of Chemistry

Chemistry was first found in 1661 and its first modern chemist was called Robert Boyle. Boyle worked with gases and was the first to disagree with the Greek idea of four elements in his book The Skeptical Chymist published in 1661. This theory was odd because the Greek were the first people to record their studies and come up with the idea of elements as well as early models and atoms. Boyle also stated that “All reality and change can...
