Question

Ionization. 25. (3) Which of the following most likely represents the successive ionization energies (IE, through IE) of a noble gas in Period 4, in kJ/mol? (select the best one) IE IE2 IE3 IE4 IES a) 1351 2350 3565 5070 6240 941 2045 2973 4144 6590 c) 419 3052 4420 5877 7975 d) 590 1145 4912 6491 8153

Answer 1

The noble gas from period 4 is kryplon (ko). The 1st lonisation energy of kr is 1351 KI/mol. It has anelutromi Configuration of [Ar] 3 dº 45 466. Here ist inoisation energy is already as we are removing elitron from 4 pb orbital. quite high a full - Thin the successive no ionization Crurgies! ase as - IE, LIE, L2E3( 2 E4 KIES TE increases as we go I from left to right in this series the charge (positive) increases which hold the outer most ė - more tightly So, option - is correct answes. for Kr- (in w/mol) 1 E, - 1351 Correct I E = 2350 answy TE = 5070 Hoption - a Es = 6240 TE) = 3565
