The diagram below shows the reaction between potassium and bromine.Describe, in terms of electrons, what happens when a potassium atom reacts with a bromine atom to produce potassium bromide.Potassium will lose one electron to form a -1 ion.Bromine will gain one electron to form a +1 ion.The oppositely charged ions are then held together by a strong electrostatic attraction.Potassium will gain one electron to form a -1 ion.Bromine will gain one electron to form a +1 ion.The oppositely charged ions are then held together by a strong electrostatic attraction.Potassium will lose one electron to form a +1 ion.Bromine will gain one electron to form a -1 ion.The oppositely charged ions are then held together by a strong electrostatic attraction.Potassium will gain one electron to form a +1 ion.Bromine will lose one electron to form a -1 ion.The oppositely charged ions are then held together by a strong electrostatic attraction.

A student compares the reactivity of the elements bromine, chlorine and iodine. He mixes these pairs of solutions and observes the reactions that occur.• chlorine solution and potassium bromide solution• bromine solution and potassium iodide solutionExplain how the reactions can be used to show the order of reactivity of the three elements.Include the colour change that the student would observe in each reaction.

Describe what happens when an atom of potassium and iodine react to produce potassium iodide.Answer in terms of electrons.The iodine atom loses one electron to form a positive ion (I+). This electron is transferred to a potassium atom.The potassium atom gains one electron to form a negative ion (K-).The positive iodide ion and the negative potassium ion electrostatically attract, forming an ionic bond.The potassium ion loses one electron to form a positive ion (K+). This electron is transferred to an iodine atom.The iodine ion gains one electron to form a negative ion (I-).The positive potassium ion and the negative iodine ion electrostatically attract, forming an ionic bond.The potassium atom loses one electron to form a positive ion (K+). This electron is transferred to an iodine atom.The iodine atom gains one electron to form a negative ion (I-).The positive potassium ion and the negative iodide ion electrostatically attract, forming an ionic bond.The iodine atom loses one electron to form a negative ion (I-).
