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 2,8,7
(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?
(a) Ionic bond is formed as element C donates its electron to element D.
(b) Element B is an inert gas as it has a complete octet configuration.
(c) The formula of the compound between A and C will be C2A as element A needs two more electrons to complete its octet.
