What is [Ne]
400
Does metallic character increase or decrease from top to bottom? left to right?
What is increase, decrease

On diagram A, explain why the carbon x peak is higher than the boron x peak
because carbons 1s electrons have greater coulombic forces than borons, because carbon has 6 protons ans boron has 5
