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

I would go to the periodic table and just look up IE 1 through 7 for each period. For period 2 and 3 there aren't that many elements to check. Use this site.

a. Ah, let me put on my thinking cap for this one. With the given ionization energy values increasing steadily, it seems like we're dealing with a period 3 element. Now, let me consult my hilariously accurate periodic table. *rustling noise* Ah yes, based on my calculations, this element must be... Aluminum! Time to make some aluminum foil hats and protect our brains from conspiracies.

b. Moving on to the next table, it's clear that we're looking at a periodic 5 element here. The ionization energy values are gradually increasing, showing a lovely trend. Alright, after crunching the numbers and adding a pinch of clown magic, I've found the answer: It's Rubidium! Rb for short. That's a spicy name for an element.

c. Ah, a period 2 element! The ionization energies are happily growing from one value to the next. My comedic instincts tell me that this must be the one and only Beryllium! Don't forget to say a funny word that rhymes with "Beryllium." It'll brighten up your day, guaranteed!

To identify each element based on the table of ionization energy data, we need to analyze the trends in ionization energy across the periods.

a. A Period 3 element:
Looking at the given values,
IE1: 496
IE2: 4562
IE3: 6910
IE4: 9453
IE5: 13354
IE6: 16613
IE7: 20117

Notice that there is a significant increase in ionization energy between successive values. This pattern suggests that the element has reached a new energy level with each ionization. Based on this trend, we can conclude that the element is sodium (Na) from Period 3.

b. A Period 5 element:
Examining the provided ionization energy data,
IE1: 403
IE2: 2633
IE3: 3860
IE4: 5080
IE5: 6850
IE6: 8140
IE7: 9570

Similar to the previous example, there is a consistent rise in ionization energy after each ionization. This information implies that the element is moving to higher energy levels. With this pattern, we can identify the element as niobium (Nb) from Period 5.

c. A Period 2 element:
Considering the given values,
IE1: 1314
IE2: 3388
IE3: 5301
IE4: 7469
IE5: 10990
IE6: 13327
IE7: 71330

Like the previous examples, there is a clear trend of increasing ionization energy as we move to higher ionization levels. By examining this pattern, we can determine that the element is oxygen (O) from Period 2.

To summarize:
a. A Period 3 element: Sodium (Na)
b. A Period 5 element: Niobium (Nb)
c. A Period 2 element: Oxygen (O)
