Answer;
-4. metallic, because the valance electrons are mobile
Explanation;
-Electrical conductivity in metals is a result of the movement of electrically charged particles.The atoms of metal elements are characterized by the presence of valence electrons (electrons in the outer shell of an atom) that are free to move about.
-Therefore; Metallic elements such as sodium and potassium conducts electricity in solid form due to the presence of delocalized valence electrons. These electrons can move freely within the structure of a metal when an electric current is applied.
Answer:
104,000 has 3 significant figure.
Explanation:
This is because all non-zero digits are significant and zeros in between non-zero digits are significant.
D. They should try to reproduce Dr. Maxwell's research to verify his results
Answer:
B
Explanation:
the group number is=valence electrons. element 1 is in group 1 element 18 is in group 8. 1<8
