The radius of an atom is generally 30-300pm. Atoms are made up of 3 types of subatomic particles. An atom is made of three subatomic particles: protons, neutrons, and electrons. Protons Exhibit a positive charge Found in the nucleus Abbreviated p+ Mass of 1.67 x 10-24g The number of protons is equivalent to the elements atomic number. Atomic # = # of p+ Electrons Exhibit a negative charge Found outside of the nucleus Abbreviated e- Mass of 9.11 x 10-28g The number of electrons in an atom is equivalent to the elements atomic number. Neutrons Do not exhibit a charge Found inside the nucleus Abbreviated n0, Mass of 1.67 x 10-24g You cant determine the number of neutrons by looking at the periodic table. Example: 1. How many protons and electrons are in an atom of calcium? Find Calcium on the periodic table. What is calciums atomic number? The atomic number of Calcium is 20. This tells us that in an atom of calcium there are 20 protons and 20 electrons. Exercise: 1. How many protons and electrons are in an atom of selenium? Ion is an electrically charged species. The number of electrons is changed when an atom is ionized to form an ion. The number of protons is never changed because protons are found in the nucleus. Cations are positively charged ions. A cation always has more protons than electrons. Example: 1. How many protons and electrons are in the potassium cation, K+? a. Start by determining the atomic number of K. Atomic number of K is 19. b. This tells us that in an atom of K there are 19 protons and 19 electrons. c. But we are considering the cation K+. The plus sign indicates that there is one more proton than electron in this ion. d. Since we cant change the number of protons we know that must remain as 19. e. To determine the number of electrons think about the number you can add to 19 to get +1. 19 + x = 1 You add 18 to 19 to get 1. The 18 represents the electrons (electrons exhibit a negative charge). This ion has 18 electrons (we let each electron equal a 1 charge so 18 electrons=-18). 19 + (-18) = 1 Anions are negatively charged ions. An anion always has more electrons than protons. Example: 1. How many protons and electrons are in the nitride anion, N3-? a. Start by determining the atomic number of N The atomic number of N is 7. b. This tells us that in an atom of N there are 7 protons and 7 electrons. c. But we are considering the anion N3-. The 3- indicates that there are three more electrons than protons in this ion. d. Since we cant change the number of protons we know that must remain as 7. e. To determine the number of electrons think about the number you can add to 7 to get -3. 7 + x = -3 You add 10 to 7 to get -3. The 10 represents the electrons. This ion has 10 electrons (we let each electron equal a 1 charge so 10 electrons = -10). 7 + (-10) = -3 Exercises: Draw a picture of a generic atom. Label the atom with nucleus, electron cloud, and subatomic particles. How many protons and electrons are in a sodium atom? How many protons and electrons are in the sodium cation, Na+? How many protons and electrons are in the aluminum cation? How many protons and electrons are in the oxide anion? How many protons and electrons are in an atom of the noble gas Ne? Chapter 2 Section 5: Atomic Numbers and Mass Numbers TNOW Homework Assignment 5 Atomic Number The number of protons in an atoms nucleus is equivalent to its atomic number. This number is found on the periodic table. Atomic number = number of p+ The symbol for the atomic number is Z. Lets look at sodium as an example. Sodium is abbreviated Na on the periodic table. In the block where Na is located, the atomic number (shown above Na) is 11; therefore Z = 11. Since Z = 11 there are 11p+ and 11 e- in a Na atom (re: atoms are neutral in charge). Atomic Mass The number under Na is the atomic mass. The atomic mass of Na is 22.99 amu. Amu is the abbreviation for atomic mass unit. One amu, 1u, is 1/12 the mass of an atom of carbon with 6 protons and 6 neutrons. 1u=1.661 x 10-24g Mass Number The mass number of an atom is equal to the sum of an atoms protons and neutrons Mass number = p+ + n0 RE: MASS NUMBER DOES NOT EQUAL ATOMIC MASS The abbreviation for mass number is the symbol A. A = p+ + n0 Exercises: Aluminum has 13 protons, 13 electrons, and 14 neutrons. What is the mass number of Al? Mg has 12p+, 12e-, and a mass number of 24. How many n0 are in Mg? An atom of an element has 55 electrons and 29 neutrons. Identify this element. Complete Symbol We represent the complete symbol of an element in the form of AZX, where A is the mass number, Z is the atomic number, and X is the symbol of the element. Example: 1. Given the fact that there are 12 neutrons in sodium, the complete symbol for sodium is 2311Na. Exercises: Give the complete symbol for: a) F with 10 neutrons b) Cr with 28 neutrons Xe with 78 neutrons How many electrons, protons, and neutrons are in an atom of: 136 C 5024 Cr For an atom of P with 16 neutrons, what is the complete symbol? How many electrons, protons, and neutrons are in 24494Pu? Example: Now, lets look at this type of data analysis in the form of a table. ElementElement SymbolZAProtonsNeutronsElectronsNitrogenN715787Calcium421416 Lets do the first row together. The symbol given is N for Nitrogen. N is atomic number 7. Atomic number is equal to the number of protons in an atom-fill in the number of protons = 7. In an atom, the number of protons = number of electrons. Number of electrons = 7. The number of neutrons is calculated using the equation A=n0 + p+ -> 15 = n0 + 7 -> Solve for n0 Fill in the rest of the table. Exercises: The volcanic eruption of Mount St. Helens in the state of Washington in 1980 produced a considerable quantity of a radioactive element in the gaseous state. The element has atomic number 86. What are the symbol and name of the element? Give the mass number of the following atoms: nickel with 31 neutrons Gallium with 39 neutrons Tungsten with 110 neutrons Give the complete symbol (AZX) for each of the following atoms: potassium with 20 neutrons Co with 33n0 Argon with 21 neutrons Zinc with 34 neutrons Fill in the blanks.
