QUESTION
Wouldl al scientistl bel morel likelyl tol findl anl elementl suchl asl Ol inl al
biomoleculel orl W?l Explainl whichl theyl wouldl morel likelyl findl andl givel
specificl physical/chemicall properties.
Answer:
Al scientistsl wouldl bel morel likelyl tol findl anl elementl suchl asl Ol inl al
biomolecule.l Largerl elementsl suchl asl Wl tendl tol forml ionicl bonds,l whilel
smallerl elementsl likel Ol tendl tol forml morel stablel covalentl bonds.l
Therefore,l elementsl suchl asl Ol arel morel favoredl byl biomoleculesl becausel
theyl tendl tol forml strongerl bondsl byl sharingl electronsl andl formingl
significantl overlapl withl otherl elements.l Asl al result,l thesel strongerl bondsl
requirel al substantiall amountl ofl energyl tol breakl theml andl allowsl thel bondsl
tol withstandl insults,l suchl asl thermall andl mechanicall stress.
