Periodic table of the elements
Periodic table, in full periodic table of the elements, in chemistry, the organized array of all the chemical elements in order of increasing atomic number—i.e., the total number of protons in the atomic nucleus. When the chemical elements are thus arranged, there is a recurring pattern called the “periodic law” in their properties, in which elements in the same column (group) have similar properties. The initial discovery, which was made by Dmitry I. Mendeleyev in the mid-19th century, has been of inestimable value in the development of chemistry.

Anastasia Posanina
Passionate about languages and cultures, I am a polyglot language teacher with experience teaching and learning several languages, including English, Armenian, Finnish, and Italian. My journey as both a learner and a teacher has shaped a dynamic, empathetic approach to language education. I understand the challenges students face at every stage of learning, and I use that insight to create clear, supportive, and motivating lessons. My teaching emphasizes communication, cultural awareness, and real-life application rather than rote memorization. I design personalized programs that balance grammar, vocabulary, and fluency practice, helping students gain confidence and express themselves naturally. I enjoy integrating authentic materials—songs, videos, articles, and conversation—to make each class engaging and meaningful. Above all, I believe languages open doors to new perspectives and connections, and my mission is to guide students toward discovering the joy and freedom of multilingual communication.
