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
Yes, CH3Cl (methyl chloride) is a covalent compound. It is formed by sharing pairs of electrons between carbon and hydrogen/chlorine atoms, which are nonmetals.
Valence in a chemical compound can be determined by looking at the number of electrons that an atom gains, loses, or shares when it forms a bond with other atoms. The valence of an element is typically equal to the number of electrons in its outermost energy level. By understanding the valence electrons of each element in a compound, one can determine the overall valence of the compound.
One way to keep track of valence electrons in an ionic compound is by using the charges of the ions involved. Valence electrons are transferred from the metal to the non-metal in an ionic bond, so the charge on the cation and anion can help determine the number of valence electrons involved in the bond.

Electrons in the outermost shell are valence electrons!

There are 26 total valence electrons in the compound PCl3. Phosphorus contributes 5 valence electrons, while each chlorine atom contributes 7 electrons. This adds up to 5 + (3 x 7) = 26 valence electrons.
In the compound Al₂O₃, there are two aluminum (Al) atoms and three oxygen (O) atoms. Aluminum has 3 valence electrons, so 2 Al atoms contribute a total of 6 valence electrons. Oxygen has 6 valence electrons, so 3 O atoms contribute 18 valence electrons. Therefore, the total number of valence electrons in Al₂O₃ is 6 + 18 = 24 valence electrons.
The compound sulfate (SO4^2-) has 32 valence electrons. This is calculated by adding the valence electrons of sulfur (6) to the valence electrons of oxygen (6 each for a total of 24), and then adding 2 additional electrons to account for the 2- charge of the sulfate ion.
They Share Electrons

A compound composed of two elements that share valence electrons is called a covalent compound. In covalent compounds, atoms share valence electrons to achieve a stable electron configuration. Examples include water (H2O) and methane (CH4).
One way to keep track of valence electrons in an ionic compound is by using the charges of the ions involved. Valence electrons are transferred from the metal to the non-metal in an ionic bond, so the charge on the cation and anion can help determine the number of valence electrons involved in the bond.

Because they are the only ones involved in bonding. For example, when an forming an ionic compound one atom loses its valence electrons and one gains electrons to make its valence electron shell complete.
Arsenic (As) has five valence electrons, as it is located in group 15 of the periodic table. In AsCl, arsenic forms a covalent bond with chlorine (Cl), which has seven valence electrons. The minimum number of electrons in the valence shell of arsenic in this compound would still be five, as it does not lose any of its valence electrons despite forming bonds. Therefore, As would have five electrons in its valence shell in AsCl.
