The number of valence electrons in a single group does not change in the s and p block elements, groups 1, 2, 13-17.
However in groups 13 -16 the so-called inert pair effect seems to indicate that the s electrons do not get involved so readiliy in bonding and the heavier elements exhibit a valency 2 less than the lighter members. E.g Gallium has Ga+ ion as well as a Ga3+.
What else can I help you with?
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
How many valence electrons are there in each atom within a silicon crystal?
There are 4 valence electrons in each silicon atom within a silicon crystal. Silicon has 4 valence electrons in its outermost shell, as it is in group 14 of the periodic table.
Elements within a group have a similar number of what?
Number of valence electrons
Is Within a family on the periodic table the number of electrons on the valence level is always the same true of false?
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.
How can you determine the number of valence electron atom has?
Look what column it is in within the Periodic Table. The first column has 1 valance electron. The second column has 2 valence electrons. The entire section of shorter columns (all metals) also have two valence electrons. The tall column after that (with Boron ) has three valence electrons. The tall column after that (with carbon) has four valence electrons. This pattern continues until you reach the final column, the noble gasses (eg. Neon, argon, xenon); these all have 8 valence electrons.

How many valence electrons are there in each atom within a silicon crystal?
There are 4 valence electrons in each silicon atom within a silicon crystal. Silicon has 4 valence electrons in its outermost shell, as it is in group 14 of the periodic table.
What are the number of valence electrons in phosphorus?
there are five valence electrons in an atom of phosphorus
The number of missing or extra electrons within an atom's outer shell?
Valence electrons
Elements within a group have a similar number of what?
Number of valence electrons
What do elements within the same group have the same number of?
valence electrons
How are the elements within row different?
They have different numbers of valence electrons.
What is the different about the valence electrons for all elements in a group?
Valence electrons for elements in the same group are the same because they are located in the outermost energy level of an atom. This common number of valence electrons is what gives elements within a group similar chemical properties.
Is Within a family on the periodic table the number of electrons on the valence level is always the same true of false?
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.
How are families within the periodic table similar?
Elements within the same period have the their valence electrons in the same principle energy level. For example, those elements in period 2, have their valence electrons in the 2nd energy level.
