Do group 7 elements react with metals
WebAug 21, 2024 · The Reactions with Oxygen. Group 1 metals are very reactive, and must be stored out of contact with air to prevent oxidation. Reactivity increases as you go down the group; the less reactive metals (lithium, sodium and potassium) are stored in oil (because of its density, lithium floats in oil, but because it is less reactive than the other … WebHow do group 7 elements (halogens) react with metals? form ionic compounds in which the halide ion carries a charge of -1.

Group 1 elements are called alkali metals because of their ability to displace H2(g) from water and create a basic solution. Alkali metals are also known to react violently and explosively with water. This is because enough heat is given off during the exothermic reaction to ignite the H2(g).
