How can one determine valence in a chemical compound?
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.

What is the difference between oxidation number and the number of valence electrons?
The oxidation number is the charge that an atom has when forming a compound, determined by the electron gain or loss. Valence electrons are the electrons in the outermost shell of an atom, which are involved in forming chemical bonds. While the oxidation number can vary based on the compound, the number of valence electrons remains constant for elements in the same group of the periodic table.
What is the Lewis theory chemical formula for Al and N?
The compound containing aluminum and nitrogen is called aluminum nitride and has the formula AlN. The aluminum atom loses its three valence electrons, and the nitrogen atom will gain the three valence electrons from the aluminum atom, and add them to its valence electrons, forming an octet. Refer to the related link below for an illustration.
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 is the compound formed between Ba and S?
Ba is a group 2 elements with 2 valence electrons. S is a group 16 element (or oxygen family) and has 6 valence electrons. Ba gives 2 of it's valence electrons to S giving both atoms an octet. They combine in an ionic compound in 1:1 proportions. The formula is BaS and it's called barium sulphate

How many total valence electrons are in the compound PCL3?
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.

The oxidation number is the charge that an atom has when forming a compound, determined by the electron gain or loss. Valence electrons are the electrons in the outermost shell of an atom, which are involved in forming chemical bonds. While the oxidation number can vary based on the compound, the number of valence electrons remains constant for elements in the same group of the periodic table.
Using silicon dioxide as an example and the periodic table as a reference.describe how to to write the formula of a covalent compound.?
To write the formula of a covalent compound like silicon dioxide, determine the number of each element's valence electrons from the periodic table (Si has 4, O has 6). Then, balance the number of valence electrons between the atoms by sharing electrons to form a stable octet (or duet for hydrogen and helium). In the case of silicon dioxide, two oxygen atoms share electrons with one silicon atom to form SiO2.
How many valence electrons does the compound sulfate have?
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.
How many valence electrons does H2O2have?
H2O2 is a compound, and the concept of "valence electrons" applies to atoms but not to compounds. If the question is or should be intended to be, "How many valence electrons did the atoms in one formula unit of H2O2 have before they reacted to form the compound?", the answer is one from each hydrogen atoms and six from each oxygen atom, for a total of 14.
What happens to the number of valence electrons when atoms combine to form a compound?
They Share Electrons

When determining the formula for a compound it is important to know the valence numbers of each element. Suppose you want to-write a formula for a compound with these two elements?
To be stable it would need to be A2B (2 of element A would give a total of 6 valence electrons + the 1 element B would give a total of 8 electrons in the covalent bond. The bond is now stable and you have a compound.)
