Calculate the number of protons in an atom of Cl Z = atomic number = number of protons = 17.Use the Periodic Table to find the symbol Cl and hence its atomic number (Z): Calculate the number of protons in the nucleus of an atom of this element.Ĭalculate the number of protons in an atom of element with symbol ClĮxtract the data from the question: Symbol of the element: Cl 5 is less than the number of known elements, so our answer is plausible.Īn element has the symbol Cl. (b) The atomic number, and hence the number of protons, cannot be greater than the number of known elements (currently 116). 5 is a whole number, so our answer is plausible. Is your answer plausible? (a) The number of protons must be a whole number, an integer.Determine the number of protons in an atom of boron Z = atomic number = number of protons = 5.Use the Periodic Table to find the atomic number of boron: What is the relationship between what you know and what you need to find out? number of protons = atomic number of element = Z.State your solution to the problem "number of protons in nucleus of the atom":ĭetermine the number of protons in the nucleus of an atom of boron.įind the number of protons in an atom of boronĮxtract the data from the question: Name of element: boron.54 is less than the number of known elements, so our answer is plausible. 54 is a whole number, so our answer is plausible. Determine the number of protons in the nucleus of the atom number of protons in the nucleus of the atom = Z = 54.What is the relationship between what you know and what you need to find out? Z = atomic number = number of protons in the nucleus of the atom.What data (information) have you been given in the question?Įxtract the data from the question: Z = atomic number = 54.(Based on the StoPGoPS approach to problem solving.)ĭetermine the number of protons in the nucleus of the atom How many protons are in the nucleus of an atom of an element with an atomic number of 54 ?
