Does an object which is positively charged contains all protons and no electrons?

Positively charged objects have electrons; they simply possess more protons than electrons.

Explanation:

2. An object that is electrically neutral contains only neutrons. Electrically neutral atoms simply possess the same number of electrons as protons.

If an atom has an equal number of protons and electrons, its net charge is 0. If it gains an extra electron, it becomes negatively charged and is known as an anion.

If it loses an electron, it becomes positively charged and is known as a cation.

The contain both protons and electrons, but they have more protons than electrons making it a positively charged object.

the device is called “ rocket engine”
