Hi, so the question here is out of the given elements, which atom is the smallest ranges.
00:07
Okay, so we have calcium.
00:09
So i have here on the board, a part of the predict table, which shows all the elements given here.
00:16
Okay, we have calcium.
00:17
Try this in green calcium here, calcium here, calcium, and then magnesium.
00:24
Magnesium is on top of calcium, and then we have sodium and potassium.
00:29
Sodium and potassium.
00:32
And the last given is argon.
00:35
So argon is on the far right of the predict table compared to the four other given elements.
00:42
So what you have to remember is that the trend in the predict table is that if we are going to the left, this will have an increasing atomic radius.
01:00
So that means if we go to the right, we have decreasing.
01:06
Okay, it's the opposite.
01:08
Sorry, this will be decreasing atomic radius.
01:17
And if we go down, predictable will have increasing trend of the atomic radius also...
