Atoms vs. Ions

An Atom Is Electrically Neutral Because *

Neutral

Atoms are said to be electrically neutral because in an atom there are same number of protons & electrons. By definition, an atom is electrically neutral (i.e. Has the same number of protons as it does electrons, plus some number of neutrons depending on the isotope). If a species were charged, it is referred to as an ion (cation for positively charged and anion for negatively charged species), also by definition. When an atom is electrically neutral, it means that the overall charge of the atom is zero. Atoms are made up of. An atom contains sub atomic particles electrons, protons and neutrons. Electrons are present in the outer shells. The given atom contains eleven electrons. The atom is neutral so the number of electrons will be equal to number of protons. The electron configuration of an atom can be determined by identifying first the right order of the electron shells. The atomic number of Magnesium is 12 so we expect the electrons also sum up to 12. The condensed electron configuration is Ne 3s2. The complete configuration is 1s2 2s2 2p6 3s2. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral. Ions are more stable because their valence shell is fulfilled and therefore no sharing or bonding of electrons take place. While atoms do not have fulfilled valance shell and so, Ions are considered more stable.

Why

Atoms are neutral; they contain the same number of protons as electrons. By definition,an ion is an electrically charged particle produced by either removing electronsfrom a neutral atom to give a positive ion or adding electrons to a neutralatom to give a negative ion. When an ion is formed, the number of protonsdoes not change.

An Atom Is Electrically Neutral If

Neutral atoms can be turned into positively charged ions by removing oneor more electrons. A neutral sodium atom, for example, contains 11 protonsand 11 electrons. By removing an electron from this atom we get a positivelycharged Na+ ion that has a net charge of +1.

Atoms that gain extra electrons become negatively charged. A neutral chlorineatom, for example, contains 17 protons and 17 electrons. By adding one moreelectron we get a negatively charged Cl- ion with a net charge of -1.

An Atom Is Electrically Neutral When

The gain or loss of electrons by an atom to form negative or positive ionshas an enormous impact on the chemical and physical properties of the atom.Sodium metal, for example, which consists of neutral sodium atoms, burstsinto flame when it comes in contact with water. Neutral chlorine atoms instantlycombine to form Cl2 molecules, which are so reactive that entire communities are evacuatedwhen trains carrying chlorine gas derail. Positively charged Na+ and negatively charged Cl- ions are so unreactive that we can safely take them into our bodies wheneverwe salt our food.
