Providing study notes, tips, and practice questions for students preparing for their O level or upper secondary examinations. To avoid this, the metals are stored under oil, They also react vigorously with water, forming the alkaline hydroxide and releasing hydrogen gas, Because alkali metals are such reactive metals, they combine directly with reactive non-metals such as the halogens to form salts, low melting and boiling points - increases down the group, elements become darker and solidify down the group, because of their atomic size, which increases down the group, therefore it becomes more difficult for the nucleus to attract an electron to form an ion, most reactive is fluorine; least reactive is iodine, all halogens form ions with single negative charge eg F, Any halogen above another in the group will displace it from a solution of its salt ---->, least reactive elements in the gaseous state; do not form bonds, have stable electronic configuration with full electrons on their shells.
