During a reaction, a halogen chemically combines with a group 1 element to form a compound. how does this reaction occur, based on the atomic structure of each element? a) a halogen atom loses an electron to an atom of group 1 element b) a halogen atom gains an election from an atom of a group 1 element c) a halogen atom loses two electrons to an atom of a group 1 element d) a halogen atom shares an electron with an atom of a group 1 element

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law? 1)high pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker 2)high pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant 3) low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker 4)low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
