How can I say these sentences in Korean? It may look nonsense but I need to learn ~ 1- Draw a periodic table to show periods, groups and orbitals. 2- What is period and group? What are the features? What are the names of the groups? 3- Explain how the number of elements in each layer in the periodic table is determined. 4- In the periodic table, determine the location of the first twenty elements according to the layer electron order. 5- Explain how the elements in the periodic table are examined. It may seem weird but I'm waiting for someone to translate these sentences into Korean. Thanks~
