Question

why do atoms always contain the same number of electrons and protons?​

Answer 1

Answer:

Atoms generally are stable(except the ones of radioactive elements). This stability is obtained only when they're electrically neutral. And since protons and electrons carry equal but opposite charge, an equal number of protons mean that they have neutral charge. Hope this helps!

Answer 2

Answer:

To become neutrally charged.

Explanation:

Though atoms not always contain the same number of protons and electrons, because they have the tendency to fill complete their valanced shell, either by donating or receiving electrons. But, if some atoms have equal number of protons and electrons, they're neutral in change and do not react much.
