Based on this, Individual electrons in graphene have almost no mass compared to the other particles.
The material graphene consists of a single layer of carbon atoms arranged in a hexagonal lattice.
Electrons flowing through graphene can be scattered from impurities (such as foreign atoms in the lattice), from other electrons and from lattice vibrations known as phonons.
What happens to the electrons in graphene?
According to the researchers, such high values are a result of the photo thermoelectric effect. “It turns out that when you shine a light on graphene, the electrons in the material heat up, and remain hot, while the underlying carbon lattice remains cool,”
Why are electrons massless in graphene?
Yes, low energy electrons and holes in graphene can be thought of as massless because of the linear dispersion of the band structure near the K points.
This is an analogy to the relativistic energy dispersion E2=P2C2+M2C4, which becomes linear in momentum for m=0.

Since metals are malleable they are able to be bent and shaped.
Firstly, Ionic solids can't conduct electricity, this is because of the close packed structure partly caused by the strong attraction between the delocalised electrons and the positively charged ions in the lattice structure (the close packed structure is also partially due to the fact it is in a solid state, it's not just solely to the ionic bonds). As the structure is so close packed, the ions are not free to move so electricity cannot be conducted.
Secondly, high melting and boiling points (counts as a physical property as it can be observed) as there is high attraction between the oppositely charged entities in the ionic lattice, added to by the sheer number of ionic bonds and resulting electrostatic attraction in a lattice (aka strong and plentiful ionic bonds) mean lots of energy is needed to overcome these bonds in order to change state.
Thirdly, they are usually hard and brittle as the lattice is a huge structure that is held rigidly in place by the strong electrostatic attraction arising from the ionic bonds.

What elem eat is this? That has three orbitals? Usually the first orbital will contain only two electrons. The second orbital would contain four, the third would contain 16
