The charge of the nucleus of any atom is always?

The charge of the nucleus of any atom is always positive because it is composed of protons and neutrons. Protons carry a positive charge, while neutrons are neutral. The presence of protons in the nucleus gives the nucleus an overall positive charge, which is a fundamental property of all atomic nuclei.

This positive charge is crucial for the atom's interactions with other atoms and particles, as it attracts negatively charged electrons that orbit around the nucleus. The balance between the positively charged nucleus and the negatively charged electrons is what holds the atom together, defining its structure and stability. This characteristic of the nucleus being positively charged is consistent across all elements in the periodic table.
