Question

Can anyone help me identify these elements using Ionization Energies?
Analyze each table of ionization energy data (in kJ/mol) to identify each element.

a. A Period 3 element (1 point)
IE1: 496, IE2: 4562, IE3: 6910, IE4: 9453, IE5: 13354, IE6: 16613, IE7:20117

b. A Period 5 element (1 point)
IE1: 403, IE2:2633, IE3: 3860, IE4:5080, IE5: 6850, IE6: 8140, IE7: 9570

c. A Period 2 element (1 point)
IE1: 1314, IE2: 3388, IE3: 5301, IE4: 7469, IE5:10990, IE6: 13327, IE7: 71330

Answer 1

A should be sodium

Answer 2

C is oxygen because it has 8 electrons with 6 in its second shell. And two in its first shell. Should be a high jump in IE after all 6 e are removed from its outer shell.

Answer 3

thanks so much!

Answer 4

For the second it would be rubidium

Answer 5

Absolutely! No problem
