Name the three parts of an atom and where they are located. Protons- inside Nucleus Neutrons- inside Nucleus Electrons- outside Nucleus in the Electron Cloud What charge does each part of the atom have? Protons...Positive + Neutrons...No charge (Neutral) Electrons...Negative What part of the atom is responsible for an atom’s ability to bond with other elements? Electrons What are the three categories on the periodic table? Metals, Metalloids, & Nonmetals How is the periodic table organized? Into periods(rows) and groups(columns) based on the atomic number What is the name of Group 1? Alkali Metal What is the name of Group 2? Alkaline Earth Metal What is the name of Groups 3-12? Transition Metals What is the name of Group 17? Halogens What part of the atom is responsible for an atoms identity? Protons What is the name of Group 18? Noble Gas How do you know the number of protons an atom has? Atomic Number How many electrons are in the outer level for Group 1? 1 electron How do you know the number of electrons an atom has? The # of electrons = the number of protons (Atomic Number) How many electrons are in the outer level for Group 2? 2 electrons How many electrons are in each energy level? 1st energy level – 2 2nd energy level – 8 3rd energy level – 18 How many electrons are in the outer level for Group 13? 3 electrons What is the atomic mass? The mass of an atom; the # protons + # of neutrons What parts of the atom account for the atomic mass? protons & neutrons What is an isotope? An atom that has the same number of protons but a different number of neutrons Are isotopes always the same element? Why? Yes, the # of protons determines an atom’s identity and it does not change with an isotope of that element. Define periodic. Repeated in a regular pattern or interval What is the periodic table? An aid used to describe and show properties of the known elements How many electrons are in the outer level for Group 14? 4 electrons How many electrons are in the outer level for Group 15? 5 electrons How many electrons are in the outer level for Group 16? 6 electrons How many electrons are in the outer level for Group 17? 7 electrons How many electrons are in the outer level for Group 18? 8 electrons What does the # of electrons in the outer energy level indicate about the element? It’s ability to form chemical bonds with other elements; it’s chemical reactivity
