The atomic number Z is the numbor of protons in the nucleus of an atom of an element. Each element has a unicue number of protons. For oxample, an atom with 47 protons is always a silver atom and has an atomic number of 47 . The atomic number is used to distinguish different elements from one anothee. The mass number A is the sum of the number of protons and neutrons in the nucleus of an atom of an element. Aloms that have the same atomic number but different mass numbers are called isotopes. For example, all atoms with atomie number 6 are carbon atoms, but carbon atoms with mass numbers of 12 and 13 . are isotopes of one another. Each element is assigned a unique chemical symbol. For example, the symbol for hydrogen is H, and the symbol for oxygen is O. Some elements have symbols based on their names in ianguages other than Englth. For examplo, the symbol for iron is Fe, which is basod on the Labin fecrum: The alomic nurboer, mass number, and chemical symbot are often combined to describe a given atom. For example, an atom of lithium (Li) with atomic number 3 . and a mass number of 7 could be witten ? Li. Since the atomie number and the symbol are both unique to a given element, the alomic number is often left off of this notation, leaving Lal. Part A Which subolomic particlo(s) are found in the nucleus of the alom? Enter the subatomic particle or particles separated by commas. The atomic number of carbon is 6 . What is the mass number of a carbon atom with 5 neutrons? Express your answer as an integer. mass number = Part C An atom has a mass number of 30 and 16 neutrons. What is the atomic number of this atom? Express your answer as an integer. An atom of sulfur is represented by 1633S. How many neutrons are in the nucleus of this atom? Express your answer as an integer. Part E Give the nuclear symbol for the isotope of argon for which A=38 ? Enter the nuclear symbol for the isotope (e.g.,24He)
