hi friends i have a question: what is the positively charged particle of an atom?, please. thanks in advance

An atom which acquires a positive charge is called a cation - an ion in which protons outnumber electrons.

There are two very interesting positively charged particles that are produced by removing ALL of the electrons in an atom!

A hydrogen atom consists of just one proton and one electron... no neutrons. When a hydrogen atom is ionized by removing its electron it leaves behind a single positively charged proton! And when a helium atom (two protons, two neutrons, two electrons) loses both of its electrons we are left with an alpha particle. In fact it's rather difficult to strip a helium atom of both of its electrons, so alpha particles are usually generated as is (without electrons) from various radioactive decay processes. Note, we don't normally refer to an alpha particle as an ion since there are no other electrons in the structure - it is simply equivalent to a helium nucleus.

Addendum:

Depending how many electrons an atom has in its outer shell in can lose one, two, three or more. For example, atoms in Group I of the periodic table will lose one electron to acquire a single positive charge, e.g. H+, Li+, Na+, K+. (Note, H+ is a proton!). Group II elements will tend to lose two electrons to become doubly charged ions, e.g. Be2+, Mg2+, Ca2+.

An atom which has lost an electron, will now be positively charged. It is called an positive ion. If the Hydrogen atom loses an electron is is left as a proton.

A positively charged particle of an atom is called a proton and it resides within the nucleus of an atom.
