Just look at how many columns it is from the left side, sodium has 1 valence electron, magnesium has 2... chlorine has 7 and argon has 8
The oxidation state is the difference between 8 and the number of valnce electrons, excepting transition metals.
The periodic table can be used to quickly determine characteristics (number of valence electrons for example) of an element.
yes, the number of dots represent the number of valence electrons in the periodic table.
the group number of the periodic table shows the valence electron. such as :- sodium is placed in group 1 and have valence electron.
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
When moving down a column in the periodic table, except for the first period of column 18, the number of valence electrons remains unchanged.
Each group/family on the periodic table can determine valence electrons by the last number of the group/family number, like helium. It's a noble gas that has 8 valence electrons because it's on the 18 family/group
The periodic table can be used to quickly determine characteristics (number of valence electrons for example) of an element.
yes, the number of dots represent the number of valence electrons in the periodic table.
the group number of the periodic table shows the valence electron. such as :- sodium is placed in group 1 and have valence electron.
the valence electron number equals the group number. the principal energy level equals the period number it's located in.

2
One valence electron.
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
No, the number of valence electrons does not stay the same throughout the horizontal rows on the periodic table. The number of valence electrons stays the same throughout the vertical columns of the periodic table.
They determine many things. They can be used to predice hybridization, determine octet, be used to assign formal charges. The simplest answer would be for a intro to chem class, they determine the number of electrons in the atom's "outer ring"
you must plot out the element like protonéatomic number by using the bhor diagram
