valence electrons
The number of valence electrons remains the same
lanthanoids and actenoids
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.
The group no. of Lithium is 1 and its period number is 2.
Fermium (Fm) is in Group 7 in the Periodic Table.

The group no. of Lithium is 1 and its period number is 2.
As you move down group 2 in the periodic table, the number of valence electrons in each atom remains the same, at 2. This is because elements in the same group have the same number of valence electrons, regardless of the period they are in.
Top row, of the bottom two rows on the Periodic Table. (Period 6, starting at group 4)
Fermium (Fm) is in Group 7 in the Periodic Table.
As you move from left to right on rows, or across periods and top to bottom, or down a group, the number of protons increases.
Tungsten is located in the periodic table in the 6th period, 6th group, which makes it part of Group 6. It has the atomic number 74 and the chemical symbol W.
It is group 8.
