What does the number of valence electrons tell you about a given element?

If its positive it tells u that it has that number of valence electrons.
If negative it tells you that it requires that number of electrons to make the valence electrons filled up/stable.
If you know which Ion it is, you know the number of valence electrons of the neutral Atom. It corresponds to the group in the Periodic Table, the element is in. For example: Mg. It's in group 2, so it has 2 valence electrons.
The oxidation number now tells you how many more or less electrons the atom has. For example: Mg(II) has 2 positive charges, hence two electrons less. That means it has 0 valence electrons.
Take complete number of valence electrons, subtract the oxidation number and you get the number of valence electrons in the ion.

∙ 11y agoThe number of valence electrons will tell you how reactive the element is. Take the noble gases, for instance. Xenon is one of them, it has 8 valence electrons which means that the valence is filled and is stable. Xenon then won't readily bond with other elements because it has already filled it's valence. Now hydrogen has one electron in it's outer shell [it needs two] so it will react with many things as to fill it's valence.
TL;DR how reactive the element will be

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.
How can the number of core electrons be determine from the periodic table?
By finding the atomic number minus the group number
How do you find valency of an element?
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
For a given element all atoms of that element have the same number of?
The identity of every element is given by the number of protons in the nucleus. To keep electrical neutrality, they also have the same number of electrons.See the Related Questions for more information about protons, neutrons, and electrons in atoms.
What re valence electrons?
Valence electrons are: In chemistry, those electrons found in orbits farthest from the nucleus of the atom. These electrons determine the way in which the atom will combine with other atoms, and thus determine its chemical properties.
Does the valence electrons equal the number of protons?
Rarely. The number of valence electrons of an element depends on it's position on the periodic table. Any given element can have between 1-8 valence electrons. The number of valence electrons increases left to right on the periodic table, while the number of protons, which determine the atomic mass and identity of an element, increase in general. Therefore the number of valence electrons can only equal the number of protons at the 8th element and below (neon).
What is the relationship between the number of valence electrons and conductivity of a given element?
I suppose that a relation doesn't exist.

The Roman numeral at the top of a column on the periodic table indicates the number of?
They represent the valance electrons in each element. Roman numerals do no represent the valence electrons but it is the group number given by mendeleef.
What are the properties of a verical column of the periodic table?
The element in a given vertical column (or groups) have the same number of valence electrons and hence have similar properties.
How can the number of core electrons be determine from the periodic table?
By finding the atomic number minus the group number
How do you find valency of an element?

What are dot diagrams used to represent?
Outer electrons

How do you find the number of valence elections?
To find the number of valence electrons for an atom, you need to look at its electron configuration. The valence electrons are the electrons in the outermost energy level of an atom. You can determine the number of valence electrons by looking at the electron configuration or the periodic table. For main group elements (Groups 1, 2, 13-18), the number of valence electrons is given by the group number. For example, group 1 elements have 1 valence electron, group 2 have 2 valence electrons, and so on.
