The number of valence electrons determine the chemical properties of a particular element. For example, elements in group 1 tend to donate its valence electron away to produce its stable +1 ion. It also explains the formation of -1 ions from group 17 elements (halogens).

What do you notice in the number of valence electrons of metal?
The ability of an atom to loss this number of electrons.
What do you notice about the number of valence electrons as you move from left to right across a row or period?
The number of valence electrons increases from left to right across a period.
What do you notice about the number of electrons in each valence shell of noble gases?
All the noble gases have 8 electrons in their valence shell except helium which have 2 electrons in its valence shell.
What do you notice about the number valence electrons?
left to right across on a row or a periodic table
What is the expected number of valence electrons for a group 3 A element?
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
What do you notice in the number of valence electrons of metal?
The ability of an atom to loss this number of electrons.
What do you notice about location of these elements?
They have the same number of valence electrons
What do you notice about the number of valence electrons as you move from left to right across a row or period?
The number of valence electrons increases from left to right across a period.
What do you notice about the number of electrons in each valence shell of noble gases?
All the noble gases have 8 electrons in their valence shell except helium which have 2 electrons in its valence shell.
What do you notice about the number valence electrons?

What do you notice about the number of valence electrons as you move down or up a group or column in the Periodic Table?
The number of Valence electrons of an element is the same number as the element's group number. E.g. Hydrogen is in Group 1. Therefore it has 1 valence electron. Another e.g. Oxygen is in Group 6. Therefore it has 6 valence electrons.
How do you find number of valence electrons?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
What is the number of valence electrons for He?
Two valence electrons.
Number of valence electrons in Ga?
3 electrons !
How do you find the number of non-valence electrons?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
How can you find the number of valence electrons?
the number of valence electrons is the number group on the table its on
Which number tells you the number of valence electrons?
The group numbers tell the number of valence electrons. Without looking on the group number you can also tell the number of valence electrons by looking at the highest energy level in the electronic configuration.
