I'm afraid your question makes no sense whatsoever......

Why does beryllium and helium have the same valence electrons but not the same chemical properties?
Helium (He) and Be2+ ion (not beryllium element) have the same number of valence electrons (two). But their properties are different as they differ in the number of protons (2 for helium, 4 for beryllium) and hence they differ in ther properties.
Do helium has the same number of electrons in the outer shell as in magnesium?
Yes, helium only has two electrons which makes up its valence electrons (also known as an outer shell) and magnesium also has two valence electrons.
Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.
Where are elements with the same number of valence electrons?
All elements in the same group have the same number of valence electrons.
Does an element's number of valence electrons equals the element's number of protons?
Only hydrogen and helium have the stated property. For all heavier elements than these two, the number of valence electrons is less than the total number of electrons, which must be the same as the number of protons in all neutral atoms.

Yes, helium only has two electrons which makes up its valence electrons (also known as an outer shell) and magnesium also has two valence electrons.
In group 8 on the Periodic Table what element does not have 8 valence electrons?
Helium. It has 2 electrons in its single shell.
Are valence electrons the number of protons?
Only for hydrogen and helium are these two numbers the same. All other elements have at least two non-valence electrons, and the total number of electrons must be equal to the number of protons. Therefore, in all elements except hydrogen and helium, the number of valence electrons is less than the number of protons.
What do elements in families have in common?
they all have the same amount of valence electrons. Except with group 18 they all are the same except for Helium which has 2 valence electrons.
Which atoms have the same valence as helium?
Helium has 2 valence electrons. Group 2 elements (alkaline earth metals) also have 2 valence electrons.
What have the same number of valence electrons?
All elements in the same group have the same number of valence electrons.
Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.
Where are elements with the same number of valence electrons?
All elements in the same group have the same number of valence electrons.
What element have the same valence electrons as neon?
Argon(Ar) and Helium(He)
Elements in the same group have similar properties because they have the same?
the same number of electrons needed to fill their octet, the same number of valence electrons,
Elements that have the same number of valence electrons are?
All elements in the same group have the same number of valence electrons.
