What else can I help you with?
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.
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.
Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.
Why do neon and helium have different number of dot in their Lewis structures if they are in the same group?
Neon and helium have different number of valence electrons, which determine the number of dots in their Lewis structures. Helium has 2 valence electrons and will have 2 dots in its Lewis structure, while neon has 8 valence electrons and will have 8 dots in its Lewis structure, following the octet rule.
Does helium have the same amount of valence electrons as the others in its group?
No it does not, there are shells and orbitals that determines how reactive an atom is. Helium has 2 valence electrons, which fill up its entire shell, so it is like a noble gas. the other noble gasses have 8 valence electrons, which fill up their entire shell.
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.
Which elements tend to possess the same number of valence electrons?
Elements in the same group or column of the periodic table tend to possess the same number of valence electrons. For example, all elements in Group 1 (such as lithium, sodium, potassium) have 1 valence electron, while elements in Group 18 (like helium, neon, argon) have 8 valence electrons except for helium, which has 2.
Which atoms have the same valence as helium?
Helium has 2 valence electrons. Group 2 elements (alkaline earth metals) also have 2 valence electrons.
In group 8 on the Periodic Table what element does not have 8 valence electrons?
Iron (Fe) is in group 8 on the Periodic Table and it does not have 8 valence electrons. Iron has 2 valence electrons in its 4s orbital and 6 valence electrons in its 3d orbital, making a total of 8 valence electrons.
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 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.

What element have the same valence electrons as neon?
Argon(Ar) and Helium(He)
Where are elements with the same number of valence electrons?
Elements with the same number of valence electrons are found in the same group or column of the periodic table. This is because elements in the same group have the same number of valence electrons, which determines their chemical properties. For example, all elements in group 1 have 1 valence electron.
