Four elements A, B, C and D have the following electron arrangements in their atoms:
A 2, 8, 6
B 2, 8, 8
C 2, 8, 8, 1
D 2, 7
(a) What type of bond is formed when element C combines with element D?
(b) Which element is an inert gas?
(c) What will be the formula of the compound between A and C?
(b) The element B is an inert gas as it has complete octet configuration.
(c) The formula of the compound between A and C will be C2A. This is because A needs two electrons to complete its octet.
