Answer:
They use a hard shell, but not hard enough though because we humans can get through them hehehe
Answer:
However, graphene has far fewer electrons than copper, so in graphene the electrical current is carried by only a few electrons moving much faster than the electrons in copper." In semiconductors, a different measure, mobility, is used to quantify how fast electrons move.
1) they have similar chemical properties.
for example fluorine from the 17th column is a non metal so does all the elements of that group.
2)they have same valence electrons in their outermost shell
example
electronic configuration of
hydrogen 1, lithium 2,1, sodium 2,8,1 and so on.
3) have same valency.
