Infer the overall electric charge on the nucleus of an atom.
Question: Infer the overall electric charge on the nucleus of an atom.
In this blog post, we will learn how to infer the overall electric charge on the nucleus of an atom. The nucleus of an atom is composed of protons and neutrons, which have different electric charges. Protons have a positive charge, while neutrons have no charge. The overall electric charge on the nucleus is the sum of the charges of all the protons and neutrons in it. To infer the overall electric charge on the nucleus, we need to know two things: the number of protons and the number of neutrons in the atom. The number of protons is equal to the atomic number of the element, which is usually written as a subscript before the symbol of the element. For example, carbon has an atomic number of 6, which means it has 6 protons in its nucleus. The number of neutrons is equal to the mass number of the isotope, which is usually written as a superscript before the symbol of the element. For example, carbon-12 has a mass number of 12, which means it has 6 neutrons in its nucleus. To infer the overall electric charge on the nucleus, we simply multiply the number of protons by their charge (+1) and add it to the number of neutrons multiplied by their charge (0). For example, carbon-12 has an overall electric charge on its nucleus of 6 x (+1) + 6 x (0) = +6. This means that carbon-12 has a positive charge on its nucleus. In general, atoms are electrically neutral, which means that they have the same number of electrons as protons. Electrons have a negative charge, so they cancel out the positive charge on the nucleus. However, atoms can lose or gain electrons and become ions, which have a net electric charge. To infer the overall electric charge on an ion, we need to know how many electrons it has lost or gained. This is usually indicated by a plus or minus sign after the symbol of the element. For example, carbon can lose four electrons and become a cation with a +4 charge, written as C^+4^. Carbon can also gain four electrons and become an anion with a -4 charge, written as C^-4^. To infer the overall electric charge on an ion's nucleus, we subtract the number of electrons lost or gained from the number of protons and multiply by their charge (+1). For example, C^+4^ has an overall electric charge on its nucleus of (6 - 4) x (+1) = +2. C^-4^ has an overall electric charge on its nucleus of (6 + 4) x (+1) = +10. As you can see, inferring the overall electric charge on the nucleus of an atom or an ion is not very difficult if you know some basic facts about atomic structure and notation.
