Ni-Nickel. In its natural form its a neutral atom since
Number of proton=Number of electron.
However when Ni wants a stable outer shell of electrons, it loses electrons to obtain a stable octet. After losing electrons, the number of protons is higher.
Hence it has a positive charge making it a cation.
Remember all metals give away electrons to get a positive charge.
Oxygen is neither a cation nor an anion. It is a neutral element.
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).
Silver is normally not a cation or an anion, it is an element. Once it becomes an ion however, it will become a CATION with a +1 charge (Ag^+).
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.
Lithium is cation, because it is positivelycharged. Whenever a single element is positive , like calcium, it will be cation.While oxygen, which is negatively charged, will be anion.
Oxygen is neither a cation nor an anion. It is a neutral element.
Fluorine is an element. Fluoride is an anion.
Boron is an element and is neither an anion or cation. If ionized it would tend to from B3+ and would be thus a cation.

Cesium is a cation, as it has a positive charge due to losing an electron.

Oxygen is an element. It normally forms anions.
Br is an anion. It is called bromide and is the ion form of the element bromine.
