So in this question, we want to know what happens to the metallic character of the main group elements as you move left to right, across any row, and as you move down a group.
00:12
So when looking at the main group elements, that means we're disregarding the transition metals.
00:17
The metallic character is going to decrease as we move across a group because atoms more readily accept electrons in order to complete their valence shells.
00:27
Because as we move across a group, we add more electrons to the atoms, and therefore the atoms have more valence electrons.
00:45
And metallic character has to do with the ability of the atom of the element to give up an electron in order to form a bond.
00:58
So in this case, because the atoms will more readily accept electrons as, we move across the periodic table towards the right.
01:10
The metallic character is decreasing.
01:13
So if we were to draw this on the periodic table, we would draw an arrow pointing towards the left.
01:27
And that would just show that metallic character is increasing towards the left and it is decreasing towards the right.
01:43
So metallic character will increase down a group.
01:46
This is because valence electrons are easier to remove...
