What is positive change

1.	What is positive change
Answer» In an atom, a positive charge occurs when an atom has more protons than electrons. The proton is what determines its positive charge. It is denoted with a plus (+) sign. It attracts negative charges and repels other positive charges. In NaCl, the sodium cations, Na+, are neutralized by chlorine anions, Cl -.A positive charge is also known as a cation. In general, metals lose electrons to form positively charged ions (Fe+2, Au+3, Ag+), and nonmetals gain electrons to form negatively charged ions.
