The general form of a compound can be written in the form of:

[X(a) Y(b)] ^ c

Where a and b are subscripts, and c is the superscript of the whole formula.

The relationship that we can derived here between the constants is:

(valence of X) * a + (valence of Y) * b = c

Since the formula obviously has no superscript, therefore c = 0. We also know in chemistry class that the valence of Cl is -1, therefore:

valence of X * 1 + (-1) * 3 = 0

valence of X - 3 = 0

<span>valence of X = 3</span>

The atomic number is the number of _____ an atom

The Rutherford–Bohr model of the hydrogen atom (Z = 1) or a hydrogen-like ion (Z > 1). In this model it is an essential feature that the photon energy (or frequency) of the electromagnetic radiation emitted (shown) when an electron jumps from one orbital to another, be proportional to the mathematical square of atomic charge (Z2). Experimental measurement by Henry Moseley of this radiation for many elements (from Z = 13 to 92) showed the results as predicted by Bohr. Both the concept of atomic number and the Bohr model were thereby given scientific credence. The atomic number is the number of _z_ an atom.

The element oxygen has _____ valence electrons. (Input only a whole number, such as 7.)
kipiarov [429]
Remark
The short Answer is 6. That's why the ion has a charge of minus 2. Oxygen is doing it's best to have its outer ring have 8 electrons which is the number of outer electrons contained in the outer ring of the Noble Gas Neon.
