Understanding how to use and interpret the periodic table and its trends forms the foundation of studying chemistry. Our Year 9 students have made remarkable progress in this regard, developing a solid understanding of the elements, their properties, and their interactions.
理解如何使用和解读周期表及其趋势是学习化学的基础。我们的九年级学生在这方面取得了显著的进步,对元素、它们的性质和相互作用有了坚实的理解。
In celebration of our journey through the periodic table, we would like to share some fun facts with you:
在学习元素周期表的过程中,我们想与您分享一些有趣的事实:
1. Did you know that the periodic table we use today was first proposed by Dmitri Mendeleev in 1869? It has since become one of the most important tools in chemistry.
您知道我们今天使用的周期表最早是由德米特里·门捷列耶夫于1869年提出的吗?它已成为化学中最重要的工具之一。
2. The elements in the periodic table are arranged based on their atomic numbers, which represent the number of protons in an atom's nucleus.
周期表中的元素是根据它们的原子序数排列的,原子序数代表原子核中质子的数量。
