No grade for this. However you should keep a pencil and paper nearby to record topics that you will need help with. Plan to ask those questions between now and the exam.
Dalton's atomic theory includes:
Find the average atomic mass of an element whose stable isotopes include: X - 23 45.1 % @ 22.98 amu; X-25 34.7% @ 24.87 amu and the balance X-27 @ 26.77 amu. answer in amu
What is a cathode ray?
How did Thomson determine that cathode rays were negatively charged?
The atom consists of a shapeless blob of negatively charged matter with scatter "chunks" of positive charge scattered about within it.
The atom consists of a very small, positively charged and very dense nucleus surrounded by a large region of mostly empty space occupied by widely separated electrons.
The atom consists of a very small, positively charged and very dense nucleus surrounded by a large region of mostly empty space occupied by widely separated electrons that orbit the nucleus in clearly defined paths, much like planets orbit the sun.
The sum of the neutrons and protons in a particular atom is:
The number of protons in a particular atom is:
Isotopes of a single element differ from each other in:
In order (separated by commas), give the symbol, atomic number, mass number and name of the element with atoms that contain 11 protons, 12 neutrons and 11 electrons
Where can we expect to find several elements with similar properties on the periodic table?
Name the group 1 elements.
Name the group two elements
Name the group 17 elements
Name the group 18 elements
Name the elements found in groups 3 through 12.
Name the physical property associated with the ability of a material to be pounded into thin sheets.
Name the physical property associated with the ability to be drawn into a thin wire.
Name the physical property associated with the ability to transfer heat or electricity.
