The element with atomic number 71(lutetium) is paramagnetic
This is because all its electrons is not paired . lutetium has electron configuration of (Xe) 4f^14 5d^1 6S^2
Its 5d sub shell is not paired since the d sub shell can accommodate a total of 10 electrons hence lutetium is paramagnetic
Answer:
The answer is B. balanced forces
Answer:
Polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer
Explanation:
Answer:
frequency it the measure of the wave length. The measure of the peaks and troughs is how you measure the frequency. the distance between these is the wave length.
