So if we have our periodic table, it wants to know what happens to the atomic radius as we go from left to right across the periodic table.
00:13
The first one, a, is atomic radius.
00:20
The atomic radius is going to decrease.
00:26
And then b, first ionization energy.
00:31
That's going to increase.
00:34
It's going to be harder to remove an electron.
00:36
And then c, electronegativity, that also increases.
00:51
So then for six and seven, it's asking the same question as a and b, what trend in atomic radius occurs across the periodic table? it decreases.
01:05
The second part of the question is what causes the trend...
