Use the picture below to answer the following questions

If you want to see the image fill screen, you can open the link https://www.rsc.org/periodic-table/trends
and click on first ionisation energy in the panel that says "select a trend to display"

Yes. They spell ionization as ionisation. It's because the website is British.
Question 17
17.

Which element has the highest ionization energy?

Question 18
18.

Which group of elements is always found as positive elements. Use evidence from the image to explain your answer!

Question 19
19.

Which group of elements is the group that is always found as negative ions? When thinking about your answer be sure to consider that the noble gases (He, Ne, ..... Radon) do not make ions. Use evidence from the image to justify your answer!

Question 20
20.

The rules that the article discusses are called trends because there are elements that don't follow the pattern that ionization energy increases as go from left to right and decreases and you move down a column. Look carefully and find at least two elements that violate the rules. What are the elements and where are they in the periodic table?

Question 1
1.

What is a trend in science?

Question 2
2.

What is ionization energy?

Question 3
3.

What type of electron is removed during ionization?

Question 4
4.

A group is

Question 5
5.

You can use the periodic table to figure out the number of core electrons for the first 56 element by

Question 6
6.

The distance between the nucleus and the valence electrons is larger in potassium because

Question 7
7.

Coulombic attraction is stronger when the proton and the electron are closer.

Question 8
8.

Coulombic attraction between the valence electron and the nucleus depends in potassium is reduced because

Question 9
9.

The shield effect refers to

Question 10
10.

The effective nuclear charge of sulfur is

Question 11
11.

The effective nuclear charge of calcium is

Question 12
12.

Why does the shield effect increase as atoms get larger?

Question 13
13.

Why does shielding not increase across a period?

Question 14
14.

Which element has the highest effective charge nuclear charge in period 2?

Question 15
15.

Which element in period 2 is most likely to be found as a positive ion?

Question 16
16.

Which element in period 2 is most likely to be found as a negative ion?
