Isotope Practice Today, we re going to learn about isotopes. Remember the Periodic Table of Elements? We learned that there are different types of elements or atoms that have their own number of protons, neutrons and electrons. But what you don t know is that elements come in DIFFERENT FORMS! (For example, Carbon actually has 3 forms). We re going to look at 2 of them below. EX: REMEMBER Atoms are made up of: 1. 2. 3. Carbon-12 THAT S why the atom s mass is a number like 12.011 its an average! Carbon-14 protons neutrons Protons neutrons How are Carbon-12 and Carbon-14 the same? (look at the protons). How are they different? Isotopes: two forms of the same element (because they have the same number of!) with different numbers of NEUTRONS 8
Different Neutrons?! We just learned that isotopes are different forms of the same element (because they have the same number of ) but have different numbers of. Now, how does having a different number of neutrons affect an atom? Remember that atomic mass is how much an atom weighs and also tells us the number of and. If the number of neutrons is different in isotopes, then the atomic mass will also be different. Since isotopes have different numbers of neutrons, we now have to learn how to find out the number of neutrons, protons and electrons for the isotopes. Example: Carbon comes in 3 forms. Carbon-12, Carbon-13, Carbon-14. To find the NEW number of neutrons for a Carbon-14 isotope, follow these steps: 1.) Look at the periodic table at Carbon. Find the number of protons and electrons. protons electrons. 2.) Instead of using the atomic mass from the periodic table, use the mass attached to the end of the number to find the number of neutrons. 6 C Carbon 12.01 Don t use atomic mass of 12.01. Instead, use the number at the end, which is 14 Carbon-14 So to find neutrons 14 6 (# of protons) = 8 neutrons 9
Isotope Practice Find the NEW atomic mass and NEW # of neutrons, and use the periodic table to find the # of protons and electrons. 1. Carbon-13 atomic mass # of protons # of electrons # of neutrons 2. Carbon-14 atomic mass # of protons # of electrons # of neutrons 3. Boron-10 atomic mass # of protons # of electrons # of neutrons 4. Boron-11 atomic mass # of protons # of electrons # of neutrons 5. Boron-12 atomic mass # of protons # of electrons # of neutrons 6. Hydrogen-1 atomic mass # of protons # of electrons # of neutrons 7. Hydrogen-2 atomic mass # of protons # of electrons # of neutrons 8. Hydrogen-3 atomic mass # of protons # of electrons # of neutrons 9. Oxygen-13 atomic mass # of protons # of electrons # of neutrons 10. Oxygen-14 atomic mass # of protons # of electrons # of neutrons 11. Oxygen-15 atomic mass # of protons # of electrons # of neutrons 10

Name: Date: Period: Page#: Most elements from the Periodic Table HATE being alone; in fact, they love to go on dates. Ms. Sodium (Na), who has 1 extra electron, wants to find someone to bond with. Who would be the best person to date? First of all, let s just confirm that Ms. Sodium (11) only has 1 electron to give away. Let s listen in on the Element Dating Show! Announcer: Hi! Welcome to the Element Dating Show! I m your host, Mr. Periodic. Here tonight, I have some sexy elements with me who are waiting to meet their match. Let s go ahead and meet our first contestant, Ms. Sodium. Ms. Sodium is an element who has soft, silvery white hair and loves to hang out at the beach and jump the waves. Ms. Sodium, how are you doing tonight? Ms. Sodium: Pretty well! I just want to give a shout out to my family members, the Alkali Metals! And especially to my sisters, Potassium and Lithium. Hi Po! Hi Li! Announcer: Now Ms. Sodium, you re a pretty girl. How come you haven t bonded yet? Ms. Sodium: Well Mr. Periodic, I m just waiting for that perfect element. I only have 1 available electron and I want to make sure I give it away to someone special. 29
