In terms of reactivity, Potassium(K) is the most reactive element among group 1 elements.
caesium among metals and fluorine among non metals.
These elements are for metals caesium (theoretically francium) and for nonmetals fluorine.
the single element (for A+)
single-replacement reaction
A single-displacement reaction, also named single-replacement reaction, is a type of oxidation-reduction chemical reaction when an element or ion moves out of one compound and into another-that is, one element is replaced by another in a compound.
You can identify a single replacement reaction because the reactants are a compound + an element. The products of a single replacement reaction are found by switching the element with another element in the compound. Metals switch with metals, non-metals switch with non-metals, and the most reactive element is always in the compound. A double replacement reaction can be identified because the reactants are always compound +compound. The products would also be two compounds but the elements would switch.
A single-replacement reaction
This is called a replacement reaction. When one element replaces another in a compound, it is called single replacement or single displacement. An example isZn + 2HCl ---> ZnCl2 + H2 where the zinc replaces the hydrogen in the acid to form zinc chloride.

This is a single replacement, or single displacement reaction.

one element replaces one element
A single replacement reaction involve the replacement of an element with other in the molecule as in this model:A + B-C = A-C + B.

an element and a compound
In a single-replacment reaction, atoms of an element replace atoms of another element in a compound. In a double-replacement reaction, two positive ions trade places between different ionic compounds.
When a compound is mixed with an element. KCl is more than one element put together, thus it is a compound. Sodium (Na) is an element, so if you combine the two, it is a single replacement reaction.
