Question

Here, ${{\text{H}}_{\text{2}}}{\text{O}}$, ${\text{NO}}$, ${\text{CO}}$ are neutral oxide.
A) true
B) false

Answer 1

In chemistry, periodic tables play a vital role. In the periodic table there are totally $118$ elements. In the periodic table there are totally $18$ columns and $7$ rows. The columns are called groups. Hence, $18$ groups in the periodic table. The rows are called periods. Hence, totally $7$ period in the table. Oxygen is one of the elements in the periodic table. The symbol of oxygen is${\text{O}}$.Oxygen is one of the sixteen groups in the periodic table. The atomic number of Oxygen is $8$. The mass number of Oxygen is $16$. The valency of Oxygen is$2$. The stable oxidation state of Oxygen is $- 2$ .The atomic number of the element is nothing but the number of electrons or number of protons. The mass number of the atom is nothing but the sum of the number of protons and number of neutrons.

Complete answer:
We have to know that the formula of a chemical compound having one oxygen atom and another atom is called oxide. Oxygen is dianion because the oxidation state of Oxygen is $- 2$.
The molecule formula of water is ${{\text{H}}_{\text{2}}}{\text{O}}$.
The molecule formula of carbon monoxide is ${\text{CO}}$.
The molecule formula of nitrous oxide is${\text{NO}}$.
${{\text{H}}_{\text{2}}}{\text{O}}$, ${\text{NO}}$, ${\text{CO}}$are neutral oxide.
${{\text{H}}_{\text{2}}}{\text{O}}$, ${\text{NO}}$, ${\text{CO}}$are neutral oxide is true.

Option A is correct.

Note:
We have to know that the oxide of alkaline elements are soluble in water. Alkaline elements are first group elements in the periodic table. Oxides of alkaline earth elements are partially soluble in water. Alkaline earth elements are second group elements in the periodic table. The oxidation reaction means the addition of oxygen or the removal of hydrogen or the loss of electrons in the reaction from reactant to product. Compared to metal, metal oxide is high stable in nature.
