Use the electron theory to explain how one object can be negatively charged and another can be positively charged.

help

If electrons are negative, removing them will leave a net positive charge (net meaning fewer negative electrons than postivite protons).
Remember, in normal matter, the number of protons (positive) and electrons (negative) are the same.
Putting electrons in a material will make it a net negative charge.
