Two-dimensional schematic diagram of metallically positive-ion cores, and the charge clouds around the ion cores represent the dispersed valence electron can this pictures helped? i'll try search the example metal.

which means not all of the metal have free electron? and plus i got to give an example?... i'll try search more... thanks Mapes

Can someone tell me the role of 'free' electrons in a metallic bond? i've answered below here... am i right? and if there is detailed explanation? my answer : Solid metal are therefore visualized as consisting on positive-ion cores (atoms without their valence electrons) and of valence...

so that for particle without mass, the KE is the same as total energy, Wallah! i think i can get the idea right here... and this formula just a basic formula, from the book i read. Nevertheless, our modul is too huge, yet i can't find the Partical Without Mass explanation in detail... thanks...

can i forward q1 to this forum link? https://www.physicsforums.com/showthread.php?t=15641

No, Ekinetic = mc2(1/√(1 - u2/c2) - 1) [or approx (1/2)mu2] this is the formula of particle without mass isn't? but how can i prove this particle is particle without mass?
