Trends within groups Move from trends in chemical reactivity of alkali metals to chemical reactivity of halogens Which of the following are correct of group 1 elements React with oxygen to form metal oxides React with water to form a metal hydroxide and hydrogen gas Have one electron in its outermost energy level Decreasing reactivity down a group PRIMARY (if you teach the 4-11 age range) The intended context in which youâ€™d use it including the subject, level, topic and point in a particular course that you would envisage using it; The evidence you would expect the hinge-point question to elicit; What you would do in response to the evidence, either with the whole class or with particular groups of students. This strategy guide explains how you can employ peer review in your classroom, guiding students as they offer each other constructive feedback to improve their writing and communication skills.
