Which of the following is the correct definition of atomic mass?

Pink) The total mass of the electrons in an elementYellow) The total mass of the protons in the nucleus of an elementBlue) The total mass of all of the particles in an elementBased on the information given, how many protons, neutrons, and electrons does Cesium have?

Pink) p:132, n:55, e:55Yellow) p:55, n:78, e: 55Blue) p:55, n:78, e:78

Define period as it pertains to the periodic table.

Pink) A column on the periodic tableYellow) A group of elements with very similar traitsBlue) A row on the periodic table with very little in commonDefine atomic number.

Pink) The number of protons in the nucleus of an elementYellow) The number of electrons for a specific elementBlue) The total mass of all of the particles in an elementThis is a family of gasses that usually doesnt form compounds with other elements. They have a full outer shell of valence electrons.How many valence electrons does F have?How does Atomic mass change as you move across a period from left to right? Define electron.My symbol is Cu. What am I?My name is Zinc. What is my symbol?This family is located on the left side of the periodic table. It contains elements such as Mg, Ca, and Ra.How many valence electrons does Carbon have?How does the number of valence electrons change as you move across a period from right to left?DAILY DOUBLE!How much are you willing to risk?My symbol is Au. What am I?My name is Sodium. What is my symbol?This family of elements has only one valence electron.If Barium has a charge of +2, how many valence electrons does it have?How does the number of valence electrons change as you move down a group?Define atomic number.My symbol is Pb. What am I?My name is Mercury. What is my symbol?This family of elements generally has a charge of -2 and contains elements such as O, Se, and Te.If Argon has a charge of 0, how many valence electrons does it have?What is the most reactive metal?Define atomic mass.FINAL JEOPARDYHow many points are you willing to risk?ZnB3NaB4HgB5The Nitrogen FamilyC1The Nobel GassesC2The Alkaline Earth MetalsC3The Alkali MetalsC4The ChalcogensC51D17D24D32D48D5IncreasesE1IncreasesE2DecreasesE3Stays the SameE4Francium (Fr)E5The central part of an atom. contains protons and neutrons.F1The negatively charged particle in an atom.F2Define valence electron.The electrons located in the outer most electron shell.F3The number of protons in the nucleus of an element.
