They do not. Helium has two electrons in its valence shell. Neon has eight, plus two more beneath the valence shell. However, since the first energy level can only hold two electrons, helium has a full valence shell, which explains why its properties are similar to those of neon.
What else can I help you with?
What element has the fewest valence electrons A. Silicon (Si) B. Lithium (Li) C. Magnesium (Mg) D. Chlorine (Cl)?
Lithium (Li) has the fewest valence electrons among the options listed, with only one valence electron. Silicon (Si) has four, magnesium (Mg) has two, and chlorine (Cl) has seven. Therefore, the correct answer is B. Lithium (Li).
How many valance electrons does SiS2 have?
Lithium (Li) has 1 valence electron. It is in the same 'family' as Sodium (Na) and Potassium (K)
What element has the fewest valence electrons in period 2?
In period 2 of the periodic table, lithium (Li) has the fewest valence electrons, with only one valence electron. It is located in Group 1, which is characterized by having a single electron in the outermost shell. Other elements in period 2, such as beryllium and the nonmetals, have more valence electrons.
What element has the fewest valence electrons in period two?
In period two of the periodic table, lithium (Li) has the fewest valence electrons, with only one valence electron. This is characteristic of alkali metals, which are found in group one. As you move across the period, elements gain additional valence electrons, with neon (Ne) having eight.
How many valence electrons does lithium (Li) have available for bonding?
Lithium have available for bonding one electron.
What is the core electrons and valence electrons for Li ion?
Li+ ion has only 2 electrons in its only shell and they could be considered as both core and valence electrons.
If an element has 3 electron energy levels rings and 3 valence electrons what element is it?
The element is likely lithium (Li). Lithium has 3 electron energy levels (shells) and 3 valence electrons in its outermost energy level.
How many valence electrons need to be accommodated in the Lewis structure for LiCl?
You will have 8 valence electrons around Cl (it usually has 7 but gained one from Li). There are no valence electrons to show around Li because it gave it's valence electron to Cl. Answered by a chemistry teacher.
Why is lithium an element?
Li, Lithium has one electron in its outer shell. Valence electrons occupy the orbits furthest from the nucleus,
How many electrons goes a Li have?
Lithium is element #3, and it has 3 electrons.
What element has the fewest valence electrons A. Silicon (Si) B. Lithium (Li) C. Magnesium (Mg) D. Chlorine (Cl)?
Lithium (Li) has the fewest valence electrons among the options listed, with only one valence electron. Silicon (Si) has four, magnesium (Mg) has two, and chlorine (Cl) has seven. Therefore, the correct answer is B. Lithium (Li).
How many valance electrons does SiS2 have?

What is the number of valence electrons for Li and K?
Both lithium and potassium have one valence electron
What element has the fewest valence electrons in period 2?

What element has the fewest valence electrons in period two?
In period two of the periodic table, lithium (Li) has the fewest valence electrons, with only one valence electron. This is characteristic of alkali metals, which are found in group one. As you move across the period, elements gain additional valence electrons, with neon (Ne) having eight.
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 are the total numbers of valence electrons in LI2O?
To find the total number of valence electrons in Li2O, we add the valence electrons of lithium (1 valence electron each) to the valence electrons of oxygen (6 valence electrons). So, Li2O has 2 (from Li) + 6 (from O) = 8 valence electrons.
