ugh. science ._.my eye is going to start twitching if i don‘t have this answer quickly o.O so first good answer will get 10 points!DESCRIBE THE RELATIONSHIP BETWEEN METALLIC ATOMS IN A SHEET OF COPPER (OR ANY OTHER METAL) AND THEIR VALENCE ELECTRONS.thank you so much if you took the time to read this and/or actually answer it. you are a lifesaver !
There are a lot of overly simplistic views of metals, valence electrons and metallic bonding. There is the electron sea model, in which metals are described as an array of cations surrounded by a sea of mobile electrons. The electron sea model is flawed because the electrons are really not removed from the atoms, and there are no ions. Electrons can be removed with little additional energy, though, and caused to move to adjacent molecules. Therefore, a better model is one in which the metal atoms have overlapping orbitals containing delocalized electrons. This means that the electrons can be moved easily from one atom to the next. This accounts for the ease with which metals conduct both heat and electricity.
The valance electrons are like a mobile sea of electrons which are tightly warping the kernels thats why metals are hard. and they are good conductors because its mobile sea of electrons so the electrical currents move faster. think about it like this grab a bunch of pencils(kernels) and wrap then in rubber bands(valence electrons). of the pencils move so do the valence electrons that is why metals are malleable ps. oh and it is true not all electrons move only the ones in the valence shell move not the kernel so the mobile sea of electrons valence electrons
