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
She must have used the torch as Sun, the tennis ball as Earth and the marble as Moon.
it has an electrons in a fixed path together on energy levels.
THE MOLECULE HAS A C=C AND AN -OH GROUP, SO IT IS CALLED AN ENE/OL, I.E., AN ENOL. ENOLS CAN BE FORMED ONLY FROM CARBONYL COMPOUNDS WHICH HAVE ALPHA HYDROGENS. THEY CAN BE FORMED BY ACID OR BASE CATALYSIS, AND ONCE FORMED ARE HIGHLY REACTIVE TOWARD ELECTROPHILES, LIKE BROMINE.
