The elements in each column of the Periodic Table have the same number of valence electrons. None of the other characteristics listed in the question is common to all these elements.

Why does the middle part of the periodic table doesn't have any valency?
Because the highest level of electron orbitals inhabited by the elements in the middle of the periodic table are not the farthest away from the nucleus, so their valence electrons are always present.
What is the common between all the elements in the same column in the periodic table?
Elements that are contained within the same column in the periodic table are known as a group. All of the elements in the first group of the table have one electron in their outer shell.
How valence electrons can atoms of nonmetals have?
always more than 4
Does each Transition Metal on the Periodic Table only have 2 valence electrons according to the electron configuration with subshells?
Because valence electron are always in the outer most layer (here the N number). You would think that the valence would come from the D orbital but if you look attentively, there will always be a S orbital with a higher N number. Example: Sc 1s2 2s2 2p6 3s2 3p6 4s2 3d1 The valence electron will always come from the 4s2 subshell, and as you go along the period, the electrons are going to add up only in the 3d orbital.
Which two orbitals could the valence electrons be in?
Always the S and the P block.
Element within a group always have the same number of?
Elements within a group always have the same number of valence electrons.
Why does the middle part of the periodic table doesn't have any valency?
Because the highest level of electron orbitals inhabited by the elements in the middle of the periodic table are not the farthest away from the nucleus, so their valence electrons are always present.
How many valence electrons does Sulfur?
there are 6 electrons in valence shell of sulphur so it accepts two electrons to complete the octet (8 electrons in last shell) so its valency in ionic compounds is always - 2.
What is the common between all the elements in the same column in the periodic table?
Elements that are contained within the same column in the periodic table are known as a group. All of the elements in the first group of the table have one electron in their outer shell.
Are valence shell electrons always in the same energy level?
No
Why does the octet rule not always refer to a stable arrangement of 8 valence electrons?
The octet rule does not apply to transition and inner transition metals and to the first for or five elements in the periodic table.
How many valence electrons does atom Mg 26 in the ground state have?
Mg always has 2 valence electrons
Which elements is less reactive an element whose atoms have seven valence electrons or an element whose atoms have eight valence electrons?
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
How valence electrons can atoms of nonmetals have?
always more than 4
What is the Lewis diagram for P?
5 valence electrons since its in group 15 you always look at the last digit of the group for example : Kr - 8 Valence Electrons because its a noble gas only exception is He which has only 2 Valence Electrons H- 1 Valence
Is a valence electron the same thing as a electron?
Yes, but valence electrons are always in the outer electron shell of an atom.
Does each Transition Metal on the Periodic Table only have 2 valence electrons according to the electron configuration with subshells?
