Why atom is neutral?
Why are atoms electrically neutral?
Why the atoms become neutral when it shares electron ? Why do we attribute negative charge to the electron? If a neutral object is placed near a negatively charged object and is earthed, does it lose all its electrons? Negative charged parts of an atom? Why do electrons in an atom exist in discrete energy levels, and why don’t they fall into the nucleus or radiate electromagnetic energy as they orbit? Is there a reason that protons are positively charged and electrons are negative? What molecules are non-polar? Why can't electrons be frozen? Is polar molecules more reactive than non-polar, why? What is the electrical charge of a hydrogen atom? How do electrons get a negative charge? Is an atom a solid , liquid or gas ? Or is it none ? What are non-valence electrons? Why did atoms form? Why does semiconductor behave like a insulated at absolute zero temperature? Why do electrons leave the atoms in metals in a metallic bond to become free electrons? Where do they get the energy from to escape the atom? What is the excited state of an atom? What is atomicity? Why don't atoms' electrons fall into the nucleus? Why do we connect or need the neutral wire in electrical? Where are electrons found in an atom? In AC generation there are no positive and negative polarities as in DC. What does neutral in AC circuits mean? How is it safe to touch the neutral and not the phase? Why are metals good conductor of heat and electricity? Why are some materials good conductors of heat and electricity? How/Why do electrons repulse each other? Why are non-metal oxides acidic? Why are metals good conductors of electricity and heat? How is the charge of an atom determined? Why do electrons repel each other? Why do electrons revolve around the nucleus?
