After an atom has lost an electron, it becomes a cation and has a positive charge.
Further Explanation:
The atom is composed of three parts, protons, electrons, and neutrons. The neutrons are neutral, and the protons and electrons are charged particles. The electrons are negatively charged particles of the atom. Electron number determines only the electrical charge of the atom.
There are two important kinds of electrical charges on earth:
• Positive charge: They repel other objects that positively charged.
• Negative charge: They attract other objects that negatively charged
The number of an electron is lower than the proton than the atom is positively charged, whereas the number of an electron is greater than the proton than the atom is negatively charged. When an atom has lost its electron that it is considered as cation because it has a lower number of an electron than the proton.
