Question 1
Paper 2Medium5 marksFigure 1 shows the structural formula of bromomethane. Use the periodic table where needed.
Identify the element labelled A and state the period in which it is found.
Calculate the maximum number of electrons in the main energy level corresponding to the period of A.
Using your answer to (b), determine how many more electrons this main energy level can hold than the main energy level corresponding to carbon in Figure 1.
