How am I ment to label this diagram

lora16 [44]

I believe you have to label out the positive metal ion and the delocalized electrons. They're the 2 things that makes up a metal structure.

In the diagram, the circles with the + symbol are the positive metal ions, since + represents positive. And the remaining - circles are the delocalized electrons, as electrons are negative.

And for how a metal conducts electricity, since they're delocalized mobile electrons present in any metal structures, they're able to move away from the metal to the positive side of the battery and more electrons can replace their place flowing from the negative side.

Beta particles cannot penetrate very far into solids because they _____.

givi [52]

Answer: Beta particles cannot penetrate very far into solids because they have no mass.

Reason:
Penetrating power of particle depending upon the velocity and mass of particle. Greater the mass and velocity. Higher will be the penetrating power. In case of Beta particles, they are electrons. Mass of an electron is 9.1 X $10^{-31}$ Kg. Due to such negligible mass, they have very low penetrating power.
