Elements show different metallic traits as you go across the periodic table. This is due to a few important reasons:
Nuclear Charge: When you move from left to right across a period, the number of protons increases. This means there is a stronger pull between the protons in the nucleus and the electrons around it.
Atomic Radius: The atomic radius, or the size of the atom, gets smaller as you go across a period. This means the electrons are pulled closer to the nucleus, which makes the metallic character weaker.
Electronegativity: Electronegativity is how likely an atom is to attract electrons. Higher electronegativity usually means the element acts less like a metal. As you move through a period, elements tend to gain more electrons, which shows this trend even more.
These ideas help us understand why some elements are more metallic than others.
