Metal atoms have outer electrons which are not tied to any one atom. These electrons can move freely within the structure of a metal when an electric current is applied. There are no such free electrons in covalent or ionic solids, so electrons can't flow through them..
however ionic solids might be able to conduct electricity in their molten state to a certain degree
I think that the answer is a research bc it’s just sounds like that right answer
Answer:
B. ∠1 ≅ ∠2; alternate interior angles theorem
Explanation:
Assume the diagram is like the one below.
The blue lines are parallel, and the red line is a transversal.
∠s 1 and 2 are between the parallel lines but on opposite sides of the transversal.
They are alternate interior angles.
Pairs of alternate interior angles are congruent.
A. is wrong. Alternate interior angles are congruent.
C. is wrong. Consecutive exterior angles are outside the parallel lines and on the same side of the transversal. They are like the two angles marked with a blue x. They are supplementary.
D is wrong. Consecutive exterior angles are supplementary.
