Do Aluminum has the greatest number of valence electrons?
No, aluminum does not have the greatest number of valence electrons. It has 3 valence electrons. Elements in column 18 of the periodic table (noble gases) have the maximum number of valence electrons, with helium having 2 valence electrons and radon having 8.
What is the number of valency electron in helium?
Helium has two 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.
What is heliums number of valence electrons?
Helium has 2 valence electrons. Being in Group 18 of the periodic table, helium is a noble gas and has a full outer electron shell.
What is the maximum number of valence electrons that an atom can have excluding hydrogen helium and beryllium?
The maximum number of valence electrons that an atom can have is 7, as seen in elements such as fluorine, chlorine, and bromine. These elements are in group 7A of the periodic table, also known as the halogens.
Do Aluminum has the greatest number of valence electrons?
No, aluminum does not have the greatest number of valence electrons. It has 3 valence electrons. Elements in column 18 of the periodic table (noble gases) have the maximum number of valence electrons, with helium having 2 valence electrons and radon having 8.
How do you work out the number of valence electrons in a substance?
To determine the number of valence electrons in an element, look at its group number on the periodic table (group 1-18). The group number represents the number of valence electrons the element has. For example, elements in group 1 have 1 valence electron, while elements in group 18 have 8 valence electrons (except for helium, which has 2).
What is the number of valency electron in helium?
Helium has two valence electrons.
Element 3 lithium has one valence electron and element 4 beryllium has two valence electrons Element 5 boron has how many valence electrons?
Boron has 3 valence electrons.Boron has 3 valence electrons.

What is heliums number of valence electrons?
Helium has 2 valence electrons. Being in Group 18 of the periodic table, helium is a noble gas and has a full outer electron shell.
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.
How many valence electrons are in an atom of helium?
helium has 2 electrons as its atomic number is 2
What element has 4 protons and 2 electrons?
Beryllium (Be) has 4 protons and 2 valence electrons.
What is the maximum number of valence electrons that an atom can have excluding hydrogen helium and beryllium?
The maximum number of valence electrons that an atom can have is 7, as seen in elements such as fluorine, chlorine, and bromine. These elements are in group 7A of the periodic table, also known as the halogens.
How is an element's most likely oxidation state related to its valence electrons?
It indicates how many electrons are required to complete a full valence shell.
The number of valence electrons found in an atom of Group A element is equal to?
The number of valence electrons in an atom of a Group A element is equal to the group number. For example, Group 1 elements have 1 valence electron, Group 2 elements have 2 valence electrons, and so on.
