WebJul 12, 2024 · The reactivity of the metalloids depends on the element with which they are reacting. For example, boron acts as a nonmetal when reacting with sodium yet as a metal when reacting with fluorine. The boiling points, melting points, and densities of the metalloids vary widely. WebNov 9, 2024 · Reactivity The elements of the Periodic Table show various trends. These trends are broadly divided into two categories, i.e., physical properties and chemical properties. There are many observable patterns in elements’ physical and chemical properties as we move across a period or down in a group in the Periodic Table.

WebJul 4, 2024 · Fluorine is the most reactive element in the periodic table, forming compounds with every other element except helium, neon, and argon. The reactions of fluorine with most other elements range from vigorous to explosive; only O 2, N 2, and Kr react slowly. There are three reasons for the high reactivity of fluorine: Webhyperreactivity: [ hi″per-re-ak-tiv´ĭ-te ] the quality of being hyperreactive ; see also irritability .
