The metallic and non-metallic character
It is the property of the elements to receive electrons.
The non-metallic character decreases in the group.
React BR2 + 2KJ-> 2KBr + Jr
The non-metallic character in the period increases from left to right.
Cs- is the most electroppositive in the periodic system.
At the time, the non-metallic character increases from left to right, in the group the non-metallic character decreases from the top to the bottom.
The metallic character
It is the property of electron donation.
We will study metallic character in the group and period.
H, LI, NA, K, RB, CS, FR.
2Na + O2 (air) -> NA2O2 (Na peroxides).
