Helium
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.
there are 6 valence electrons in each element in group 16
simply yes
By the group number of the A columns
toward the left- apex
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...)
On the left side.
The element chlorine has seven electrons in its valence shell.
They follow a pattern for valence electrons.
These are the alkali metals (group 1 of the periodic table).
Magnesium is element 12 and belongs to Group 2 of the Periodic Table, are the outermost electrons, magnesium has two valence electrons.
the valence electrons cause the chemical reations. the valence electrons decide that element attract to which element.
