The number of valence electrons remains the same
What group is at the bottom of the periodic table?
lanthanoids and actenoids
How do you use a periodic table?
You use a Periodic Table to find the group, period, and the material of the 115 elements. You can find the the number of protons/electrons on the bottom of the symbols(which is arranged in oder). You can the mass number on the VERY bottom of the element's block. You can find out the number of neutrons by subtracting the number of protons/electrons from the mass number.
What group number is fermium in on the periodic table?
Fermium (Fm) is in Group 7 in the Periodic Table.
Why are things grouped together on the periodic table?
-An element is placed in that group of periodic whose group number is equal to the number of valence electrons.
