Periodic table is the beginning of Chemistry. This is the chances for us to understand about the periodic table before going deep. Not only understanding about periodic table is, but we also understand the elements. Here’s a short description of the periodic table:
A group of periodic table contains a similar properties element. A fact about the periodic table is that the first row of it only contains two elements which are hydrogen and helium. The elements are divided into two type: Metal and Non-Metal. The part of the picture that mentioned about “was created by Mendeleev” that’s right that the periodic table was first created by Mendeleev Dmitri. Before it was arranged by atomic mass because the world hasn’t found out about protons yet. The periodic table has changed over time and now it is arranged by the atomic number.
Covalent and Ionic bonding was our next step. To make the atoms balance and stable, there is something to do with it which is bonding. Covalent bonding is a chemical bonding the electrons were shared between atoms. It involves between non-metal and non-metal. On the other hand, ionic bonding is a chemical bonding that involves between non-metal and metal. The metal loses electrons to become a positively charged cation or became a negative charged anion. I’m looking forward to see the next step and ready to become a chemist!
