The amount of energy it takes to remove an electron from an atom
100
Which requires more ionization energy, F or Ba?
F
200
Who is Julius Lothar Meyer?
He was one of the first people to organize elements on a chart
200
What state of matter are the elements in when electrons are removed?
Gas
200
Which requires more ionization energy, Zn or Zr?
Zn
300
Who is Glen Seaborg?
He constructed the most modern version of the periodic table
300
What is the unit of ionization energy?
Electron Volt
300
Which has more ionization energy, Ag or Au?
Ag
400
How many elements are in the periodic table?
There are 117, 94 that occur naturally
400
Why does ionization energy increase upwards on the periodic table?
If an element has a lower atomic number, it has fewer shells, so the electrons are closer to the nucleus, which means that the electrons are harder to remove from the atom.
400
Which has more ionization energy, Ga or Ge?
Ge
500
What is the periodic table of elements?
It is a chart organizing elements based on similar physical and chemical properties
500
Why do elements on the right of the periodic table require more ionization energy?
Elements on the right of the periodic table, have more valence electrons so they require a larger amount of energy to remove all the electrons
