How can i look at the periodic table and tell how many valence electrons an element has?
Skiibird1993
The group of the element indicates the amount of valence electrons. For example, the alkali metals have one valence electron and is in group one whilst the halogens have seven valence electrons and are in group seven.

How does the periodic table indicate the numbers of valence electrons an element has?
By the group number of the A columns
Which element has the fewest valence electrons?
These are the alkali metals (group 1 of the periodic table).
What can you tell about the properties of this element?
The periodic table can be used to quickly determine characteristics (number of valence electrons for example) of an element.
How many valence electrons are present in an atom of an element located in group 14 on the periodic table?
4
Why is sodium the eleventh element?
Because it has 11 valence electrons Please see : Trends in the periodic table
What element whose valence electrons is full with two electrons on the periodic table?
Helium
Why is Palladium on the periodic table?
Because Palladium is an element (it cannot be broken down into other substances) and the periodic table is a table of all of the elements we know of.
How many electrons are in group16 of the periodic table?
there are 6 valence electrons in each element in group 16
Does the periodic table tell you how many valence electrons an atom of an element has?
simply yes
How does the periodic table indicate the numbers of valence electrons an element has?
By the group number of the A columns
Where are element with few valence electrons found on the periodic table?
toward the left- apex
What major change occurs as you move left to right on the periodic table?
As you move left to right on the periodic table, the number of valence electrons an element has increases. The number of valence electrons an element has corresponds to which group (column) an element is. (This rule does not apply to transition metals...)
If an element loses its valence electrons when it forms a molecule with another element where does the element live on the periodic table?
On the left side.
How many valence electrons does chlorine have?
The element chlorine has seven electrons in its valence shell.
Why are elements in the columns of the periodic table called representative element?
They follow a pattern for valence electrons.
Which element has the fewest valence electrons?
These are the alkali metals (group 1 of the periodic table).
Magnesium valence 2?
Magnesium is element 12 and belongs to Group 2 of the Periodic Table, are the outermost electrons, magnesium has two valence electrons.
