128Te-2
What was the name of the scientist who created a periodic table with gaps for elements that would later be discovered? Hint: An element is named after him
Dmitri Mendeleev
What was the piece of equipment that JJ Thomsen discovered which helped him to find that gases have magnetic and electric fields?
Cathode ray tube
What family of elements has a full p-orbital for the outermost electron orbital?
Noble gases
Write out the full electron configuration for Se-¹
1s²2s²2p⁶3s²3p⁶4s²3d104p⁵
The Number of electrons in Ba+2 + the number of neutrons in Uranium-238 =
200
Why is Helium not next to Hydrogen on the periodic table?
Helium is also non-reactive like the other noble gases - it does not have similar properties to the alkaline earth metals
What did Rutherford do to determine that there was a positively charged nucleus in the middle of the atom?
He shot alpha particles at a sheet of gold foil surrounded by a detection shield. He found that the positively charged alpha particles were repelled by the positively charged nucleus of the gold atoms
What family forms acids when mixed with hydrogen?
Halogens
