When an atom loses one or more valence electrons in order to attain a noble gas configuration
Boron is a metalloid element with the symbol B. In chemical compounds, boron tends to form covalent bonds rather than ionic bonds, so it does not typically exist as a cation or anion in its pure elemental form.
A single element cation and single element anion form a binary ionic compound, where one element is a metal and the other is a nonmetal. The metal forms the cation by losing electrons, while the nonmetal forms the anion by gaining electrons. Examples include NaCl (sodium chloride) and KBr (potassium bromide).
The cation is the metal "Cu", otherwise known as the element Copper.
Potassium is the element that is most easily reduced because it has a low ionization energy and readily loses an electron to form a +1 cation.
The cation is the Potassium - K+. KOH is not a chemical element, its a compound - more specially a base.
Alkaline-earth elements form cations.
Americium (Am) is an artificial chemical element and as a metal can form cations.

No it's an element.
Pb is the elemental symbol for lead. In this form, lead is neither a cation or an anion - it is neutral. However, lead acts like a metal and when it becomes an ion, it tends to form a cation by giving up electrons and becoming positively charged.
The cation is the Potassium - K+. KOH is not a chemical element, its a compound - more specially a base.
The loss of one or more electrons causes the formation of a cation, or positive ion.
Cesium is a cation, as it has a positive charge due to losing an electron.
Oxygen is neither a cation nor an anion. It is a neutral element.
