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

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.

## To understand how one object can be negatively charged and another can be positively charged, we need to discuss the electron theory. The electron theory is based on the fundamental particles called electrons, which are negatively charged.

In normal matter, the number of electrons is equal to the number of positively charged protons. This balance of positive and negative charges keeps objects neutral. However, it is possible to alter this balance and create charged objects.

When electrons are removed from an object, it will have a net positive charge. This is because removing negatively charged electrons leaves behind a surplus of positively charged protons. With fewer negative charges, the object becomes positively charged.

On the other hand, if additional electrons are added to an object, it will acquire a net negative charge. By adding extra negatively charged particles, such as electrons, the object now has an excess of negative charges compared to positive charges.

To summarize, an object can become negatively charged by adding extra electrons, leading to an excess of negatively charged particles. Conversely, an object can become positively charged by removing electrons, resulting in a surplus of positively charged particles.
