Erin Connors Chemistry 12/14/10 Mrs. Galfunt Atomic Structure- hx+ struc 1. Isotopes are atoms of ________ elements that have diff _______ # due to a diff # of ___________ 2. _________ is a particle with a positive charge and a mass of 1 amu 3. _________ is a particle with zero charge and a mass of 1 amu 4. _________ is a particle with a negative charge and a mass if 1/1837 amu 5. Protons have a mass of ________ and a ________ charge 6. e- have a mass of _______ and a _________ charge 7. Neutrons have a mass of _______ and a _________ charge 8. The atomic 3 is the # of _______ 9. The atomic # is _______ to each element 10. The mass # is the # of ____________ 11. ______________ is the general name for the 2 particles found in the nucleus (_______ & _______) 12. The mass # is written to the ______________ corner of an element’s ___________ 13. In _____________ gold foil experiment, _____________ were shot at gold foil most ____________ which shows that most of the atom is ______________Some were ______________ which shows that the atom has a _________________ 14. Dalton’s atomic theory stats that all elements are made of _________ which ___________ be divided. _________ of the same element are identical. Atoms of ___________ elements are __________. Two or more different atoms can combine to form ______________ 15. Bohr’s model show e- ______________ the nucleus X just like planets _____________ the sun. In this model e- travel in ______________ 16. The e- cloud model differs from Bohr’s in that e- _________ travel in __________ 17. The __________ is the region in which e- are most commonly found 18. Mass # = # __________ + # _________ 19. # neutrons= _______# - # ________ 20. The # of protons is the ______________ 21. The atomic number is the number of ______________ 22. ______________ are electrically neutral 23. As the # of protons increases, the charge of the nucleus _____________ 24. As the number of e- increase, the charge of the nucleus _____________ 25. As the # of neutrons increases the charge of the nucleus _____________ -----------------------------------------------------------------------------------------------------------------------------------------Aim: What is the structure of the atom? 1. Three subatomic particles are ______________, ______________ and ______________ 2. ______________ & ______________ are found in the nucleus 3. Because ______________ & ______________ are found in the nucleus, they are called __________ 4. ___________ are found outside the nucleus 5. The region where _____________ are most likely to be found are called _____________ 6. ____________ have a positive charge 7. ____________ have a negative charge 8. ____________ have no charge and are neutral 9. ______________ & _____________ have a mass of 1 amu 10. ______________ have a mass of 1/1837 of an amu (0) 11. The _______________ is the number of protons 12. The _______________ is unique for every element 13. Every atom of lithium (Li) will have ______________ protons which is the ______________ 14. Z is the letter used to represent the __________ #, which is the number of protons 15. _____________ & ______________ have mass 16. The mass number is the number of ______________ plus the number of ___________ 17. A is the letter used to represent the mass number, which is the mass ________________ 18. Mass # = # ___________ + # ______________ 19. In a given element, every atom must have the same # of ______________ 20. In a given element, the # of ______________ may be diff from atom to atom 21. To calculate the # of neutrons, you would perform a calculation of ________ minus __________ 22. It is possible for atoms of the same element to have a diff # of ___________ + a diff _________# 23. ______________ are 2 or more atoms of the same element with diff mass #s 24. An element is represented by a symbol. The __________ is located on the upper left. The _________ May be written on the bottom left but does not need to be written because ____________________ -----------------------------------------------------------------------------------------------------------------------------------------Atomic Structure – Hx 1. An atoms is the smallest particle of an _____________ that maintains _____________ 2. Rutherford’s experiment is the _____________ - This is what he did: - This is what he observed - This is what he concluded:
