Explanation:The atom consists of positively charged nucleus surrounded by negatively charged electrons rotating in shells,in specific,their respective orbitals.Since nucleus contains protons and neustrons in nucleus,nucleus doesn't have charge and proton is positive.So net charge is positive.If this whole condition mentioned above is followed, then the atom is said to be neutral.Or else it is unstable or ionised.Many atom models were made such as shcrodinger's model and bohr's model
