Abstract The chemical properties of metals is an important content for junior and senior chemistry learning. This part of the content involves important chemistry concepts and chemistry core literacy, such as elemental view, transformation view, particle view, STS view, as well as macro identification and micro analysis, evidence reasoning and model cognitive literacy. However, the cognitive level of junior three students is limited, and they cannot go deep into the microscopic perspective of electronic transfer in teaching, and cannot fully recognize and apply models. In order to make up for this problem, this research is based on the chemistry core literacy, and conducts the teaching research on the linking of junior and senior high school on the chemical properties of metals.
