What is the number of valence electrons in Ca and Cl?

2 valence electrons for calcium and 7 for chlorine.


How many valence electrons does cl- have?

Cl- has 8 valence electrons. This is because chlorine, in its neutral state, has 7 valence electrons (group 17), and the -1 charge of the chloride ion indicates the addition of an extra electron.


How many valence electrons does BeCl2 have?

Since Be is in the 2nd group, it should have 2 valence electrons and Cl should have 7 (in 7th group), and since there is 2 Cl, then there is 14. Add 14 Cl electrons and 2 Be electrons to get 16 electrons (valence, not total)


How many valence electrons are in SiCl3Br?

To determine the number of valence electrons in SiCl3Br, we need to account for the valence electrons of each atom in the molecule. Silicon (Si) has 4 valence electrons, each chlorine (Cl) atom has 7 valence electrons, and bromine (Br) has 7 valence electrons. Therefore, the total is 4 (Si) + 3 × 7 (Cl) + 7 (Br) = 4 + 21 + 7 = 32 valence electrons.


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.


How many electrons does (anion) CL have?

Chloride anion has 8 valence electrons.


What element have 7 valence electrons?

Fluorine is the element that has 7 valence electrons.


What don you notice about the number of valence electrons as you move from left to right across a row or the period in the periodic table na-mg-al-si-p-s-ci-ar?

The number of valence electrons increases by one as you move from left to right across a period in the periodic table. Sodium (Na) has 1 valence electron, magnesium (Mg) has 2 valence electrons, aluminum (Al) has 3 valence electrons, silicon (Si) has 4 valence electrons, phosphorus (P) has 5 valence electrons, sulfur (S) has 6 valence electrons, chlorine (Cl) has 7 valence electrons, and argon (Ar) has 8 valence electrons.


Which symbols represents a chlorine ion with a stable arrangement of eight valence electrons?

Cl-


Valence electrons are in the compound CH3Cl?

There are 20 valence electrons in CH2Cl2. C => 4 e-* x 1 (number of C in chemical formula) = 04 v.e-** H => 1 e- x 2 = 02 v.e- Cl => 7 e- x 2 = 14 v.e- CH2Cl2 = 20 v.e- *e- - this means electrons in short form **v.e- - this means valence electrons in short form


What has more valence electrons than oxygen?

All halogen elements have 7 valence electrons (group 17): F, Cl, Br, I, At.


How many valence electrons does ch2cl2 have?

Cl2 is the diatomic molecule of chlorine (Cl) . It has 14 valence electrons, 7 in each atom. When chlorine forms a chloride ion, an atom accepts an electron and becomes Cl- (negative ion).
