What is the formula for the ionic compound that forms between and atom P with 2 valence electrons and atom Q with 5 valence electrons?
Cjrusso06
P belongs to 2nd A group and Q belongs to 5th A group of Periodic Table so possible formula is P3Q2.

What is the Compound formula for sodium and argon?
It's unlikely because of the amount of valence electrons
How many valence electrons does silica have?
4
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.
What The double bond between carbon atom and two oxygen atoms has two characteristics what are they?
The answer is c. Valence electrons are shared between oxygen atoms & D. Four valence eletrons are shared
Formula formed between sulfate ion and barium ion?
Sulfate and barium both have a valence of 2, so that the compound formed between them has the formula BaSO4.

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 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 is valency of aluminium in aluminium oxide?
AL2O3: Aluminum has three valence electrons to give, the oxygen atoms can accept 2 valence electrons. With the compound being made of 3 oxygen atoms (which have 6 valence atoms individually) they accept 2 of the aluminums valence electrons. In electrical practice, this compound is an insulator. One atom or compound having 6-8 valence electrons is electrical insulator.
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.)
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
