WebFeb 10, 2024 · In general, the alkali metals are the most reactive, followed by the alkaline earths and transition metals. The noble metals (silver, platinum, gold) are not very reactive. The alkali metals, barium, radium, strontium, and calcium are sufficiently reactive that they react with cold water.

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: 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. onyx maxfor +

In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements. The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least ... WebThe number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons. onyx material
