Who Said That Atom Is Neutral? In 1897, J.J Thomson passed an electric current through a gas. He found that the gas gave off rays made up of negatively charged particles. Prior to this, atomic theory stated that atoms are neutral, there must also be positively charged particles inside an atom. Why is an atom
What Do All Atoms And Ions Of Sodium Have In Common? Sodium atoms and sodium ions have same number of protons. Each one has 11 protons. The atomic number of sodium is 11. What do all atoms and ions have in common? An ion has a different number of electrons than protons. An atom always
What Are The Principal Quantum Numbers? The principal quantum number, n, describes the energy of an electron and the most probable distance of the electron from the nucleus. In other words, it refers to the size of the orbital and the energy level an electron is placed in. The number of subshells, or l, describes
What Ions Are Present In Na2CO3? In Na2CO3 we get 2 sodium ions and 1 carbonate ion CO2−3 . How many ions are in sodium carbonate? The reason is clear: carbonate has a –2 charge, and sodium has a +1 charge. The only way for the compound to be electrically neutral is to have 2
What Will Happen To Sodium And Chlorine Atoms When They Give Or Take An Electron? When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl What happens to the electrons when sodium and chlorine atoms react? If sodium metal and chlorine gas mix under
