What element has 2 electron shells and 4 valence electrons?
Well, darling, the element you're looking for is carbon. It struts around with 2 electron shells and 4 sassy valence electrons, making it the life of the chemical party. So, if you're ever in need of a carbon copy, just remember this little fun fact.

Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
How is the noble gas element helium differ from radon?
Helium has 2 electrons and Radon has 86 electrons but both have 8 valence electrons (8 electrons in their outermost shells)
How many electron shells and how many valence electrons are in an atom of an element found in period 3 and group 16 of the periodic table?
This element is sulfur; the electron configuration of sulfur is [Ne]3s23p4. Sulfur has three electron shells cotaining 2, 8 and 6 electrons. The last six are valence electrons.
What is valency of an element having atomic number 20?
H, Li, Na, K = 1valence electrons Be, Mg, Ca = 2 valence electrons B, Al = 3 valence electrons C, Si = 4 valence electrons N, P = 5 valence electrons O, S = 6 valence electrons F, Cl = 7 valence electrons He, Ne. Ar = 0 because they are noble gases and all their electron shells are full
What element has 2 valence electrons and 4 protons?
The element with 2 valence electrons and 4 protons is beryllium. Beryllium has an atomic number of 4, indicating it has 4 protons in its nucleus. The valence electrons are the outermost electrons in an atom, and beryllium has 2 valence electrons in its outer energy level.
How can you determine the number of valence electrons for an element on the periodic table?
To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
How do you determine the number of valence electrons for an element on the periodic table?
To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
