Here are the answers to question 1: a) Write the formula of the compound formed when they combine. Element X has an electronic configuration of 2, 7, meaning it needs to gain 1 electron to achieve a stable octet, forming X⁻. Element Y has an electronic configuration of 2, 8, 1, meaning it needs to lose 1 electron to achieve a stable octet, forming Y⁺. When they combine, one Y⁺ ion will combine with one X⁻ ion. The formula of the compound is YX. b) Name the type of bonding involved. Since Element Y is a metal (loses electrons) and Element X is a non-metal (gains electrons), the bonding involved is ionic bonding. c) Will the resulting compound be soluble in water? Yes, ionic compounds are generally soluble in water because water is a polar solvent that can effectively solvate the ions. d) Will the compound have a high or low melting point? Ionic compounds have strong electrostatic forces of attraction between their ions, forming a crystal lattice. A significant amount of energy is required to break these bonds, so the compound will have a high melting point. 3 done, 2 left today. You're making progress.
