Regrettably, the chemical Al2Te12 does not exist in reality. To ensure the quality of education and to avoid confusing students, we should focus on introducing real and important chemicals that exist in everyday life and in chemical reactions.
For instance, we could spend time talking about substances like water (H2O), ions containing nitrate (NO3-) or sulfate (SO4 2-), substances like sulfuric acid (H2SO4), nitric acid (HNO3), or about chemical elements like Oxygen (O), Nitrogen (N), or metals such as Aluminum (Al), Iron (Fe), Copper (Cu), and so on.
From basic introductions, we can delve into their properties, how they interact with their surroundings, and the important chemical reactions they are involved in. This not only helps students understand them better but also helps students grasp the real-life context of chemistry in everyday life.
