Consider the following substances: P4, S8, KBr, Ti, H2O. Which could be explained as cations held together by mobile electrons?
PLease i need details
answer : Ti
explanation :
P4 is perfectly covalent crystal it cannot form cation . it is called molecular crystal
S8 it is also molecular crystal so cannot form cation
KBr can split up into ions as K+ and Br- . each K+ ion surrounded by Br- and each Br- surrounded by K+ ions. so cation doesnot surrounded by mobile electrons .
H2O is also molecular crystal . so it cannot have mobile electrons .
here Ti is perfectly metal . it can loose electrons easily forms cation .
Ti ----------------------> Ti+ + e-
the Ti+ ion is dipped in number of mobile electrons . so it is best conductor
