Now let me reflect on the topics learnt in term 1. In term one, we learnt some basic chemistry for Sec 2, which includes how covalent bonding, ionic bonding, protons, neutrons, electrons, and the periodic table. We started off with making a large periodic table using a vanguard sheet and little sheets of paper. Now let me summarise what I learnt for the term:
Elements have protons(positive charge), neutrons(neutral) and electrons(negative charge). Covalent bonding the bonding between two atoms where they share electrons to achieve the electronic configuration of a noble gas, while ionic bonding is the bonding of metallic and non metalic elements and includes the transfer of electrons to be bonded. There is also metallic bonding mentioned, but we did not learn about it.
