Periodic Table with Valences
Answers to Common Questions
Some periodic tables have Roman numerals at the tops of the columns that correspond to the number of valence electrons in the atoms' outermost shells. Other periodic tables have switched to a different system with the columns labeled 1 to 1...
you are actually going by the group number on top of the periodic table. example Hyrogen is in group one which means it has one valence. another example Si is in group 4 which means it has 4 valences. just remember each group # equal the am...
The most common oxidation numbers are +1 and 2 , - 1 and 2.

This all depends on the element's atomic number (number of protons). Since atoms have the same number of protons as they do electrons, the atomic number is essentially equal to the number of electrons as well. For example Aluminum atomic Th...

The importance of valence electrons is that atoms in the same group ("groups" in the periodic table are the vertical columns- for example, nickel and platinum are in the tenth column; therefore, in the same group). Atoms of elemen...

the valance number is the # of electrons in an elements outermost energy level. the transition elements have different valance #s and Group 1- 1 Group 2- 2 Group 13- 3 Group 14- 4 Group 15- 5 Group 16- 6 Group 17- 7 Group 18- 0

Group 3-12 are infilling the d orbitals and have a full s shell. So Sc has 3d1 4s2 all of which it can lose to be 3+ -- typical of group 3. Ti is 3d2 4s2 and so is typically 4+ (Group 4). Group 5 is typically 5+. Cr (Group 6) is by simple c...
