Question

potassium oxide chemical formula by cris cross method

Answer 1

Explanation:

The formula for potassium oxide is K2O.Potassium nitrate. Hint: We know that chemical formulas can also be written using criss-cross method. In the criss-cross method, the numerical value of the ion charge of the two atoms are crossed over, which becomes the subscript of the other ion.

Answer 2

The compound equation of potassium oxide is K2O.

Potassium Oxide Chemical Formula:

•  It contains potassium and oxygen particles. There exists an ionic connection between potassium and oxygen iotas. Hence, it is an ionic compound. An ionic compound is shaped by the exchange of electrons between the constituent molecules.  

Arrangement of Potassium Oxide:

• The nuclear number of potassium is 19. It has one electron in its peripheral shell. Thusly, it can give this electron to acquire a stable electronic arrangement.
• Additionally, the nuclear number of oxygen is 8. It has six electrons in its peripheral shell. It needs two additional electrons to finish its octet.
• Accordingly, during the development of potassium oxide, two potassium particles move two (one electron each from one potassium iota) electrons to an oxygen molecule to frame an ionic connection between them.
