Question
Chlorine atoms have 7 valence electrons.Determine what happens in a molecule of chlorine gas (Cl2).One chlorine atom transfers an electron to the other chlorine atomTwo new electrons are createdThe two chlorine atoms share a pair of electrons
Solution
In a molecule of chlorine gas (Cl2), the two chlorine atoms share a pair of electrons. This is because chlorine is a non-metal and non-metals form covalent bonds by sharing electrons. Each chlorine atom has 7 valence electrons and by sharing one electron with another chlorine atom, they both achieve a stable electron configuration of 8 electrons in their outermost shell. This shared pair of electrons forms a single covalent bond, holding the two atoms together in a molecule of Cl2. So, the correct answer is "The two chlorine atoms share a pair of electrons".
