Hello, my name is Martina and I'm a chemistry teacher. I am originally from Germany but have been living in this country for the past 10 years. I love teaching and helping students understand the complex world of chemistry. Today, we are going to be learning about chemical bonding and how it affects the properties of elements.
I hope you're all ready to learn because today is going to be a fun and exciting class!
