lose an electron
For an atom to become positively charged, it must lose electrons.
However, oxygen is a non-metal and is an anion. Since it only needs one electron to complete its outer shell of valence electrons, it tends to gain electrons rather than lose them and forms covalent bonds (where electrons are shared).
Outside of some circumstances
Protons, they have a positive charge.
The proton has one unit of positive charge (+1). There is no reason for it to give off its charge, and it doesn't do that. It just sits there, with its charge intact, being a proton.

You can give it a positive charge, but that is mainly done by rubbing something on the surface you'd like to be positive. The thing ( fur, hair, or other material that cause much frictions) will rub away electrons from the surface, causing it to become positive. In a lab you could technically add positive ions to make a material positive, but outside that it can hardly or not at all be done.
To make something negatively charged, you can add extra electrons to the object. Electrons have a negative charge, so adding more of them to an object will give it a net negative charge.
A neutral object contains equal numbers of positive and negative charges, resulting in no overall charge. This balance of charges cancels out to give the object a net charge of zero.
negative
A neutral object can be given a positive charge by transferring electrons away from the object, leaving a deficiency of negative charges. This can be achieved through methods such as rubbing the object with a material that readily donates electrons, causing the neutral object to become positively charged due to the imbalance of charges.
No, you do not need to touch an object to permanently give it a charge. You can induce a charge on an object through methods like friction, conduction, or induction. This charge can persist on the object even after you remove your contact.

POSITIVE.
To determine the surface charge density of an object, you can divide the total charge on the object by its surface area. This will give you the amount of charge per unit area on the object's surface.

protons
An object gives up one or more protons to get a positively charged objects and absorbs one or more electrons to get a negatively charged objects. This happens when two objects are rubbed together (ex. when you rub your feet on the carpet to give some one a shock;rubbing balloon on one's hair)
The protons in the nucleus are positively charged, and their presence is what gives the nucleus an overall positive charge. Electrons balance this positive charge with their negative charge, resulting in a neutral atom.
