1.4 Explain​ ​why​ ​atoms​ ​contain​ ​equal​ ​number​ ​of​ ​protons​ ​and​ ​electrons​ ​

Question 1

Why do atoms contain equal numbers of protons and electrons?

Answer 1

Atoms are neutral, and the charges on a proton are +1 and on an electron are -1. Therefore, the amount of protons equals the amount of electrons, so that the charges cancel.
