In polar covalent bond two different type of electrons share electrons but in non polar covalent bond two same type of atoms share equal number of electrons
examples of non polar covalent bonds are cl2,n2,o2
examples of polar covalent bond is wter molecule H2O
Explanation:
An atom consists of electrons, protons, and neutron. The protons and neutrons are present inside the nucleus whereas the electrons are present outside the nucleus.
These electrons revolve around the nucleus in circular motion. Therefore, an electron pair surrounds the central atom of a molecule. It is known that an electron contains a negative charge and like charges repel each other.
Hence, in an atom the force of repulsion between electron pairs pulls the atoms away from each other.
As a result, a molecules atoms are as far away from each other as they can get.
The question is incomplete, complete question is ;
While idly tossing some keys from hand to hand one day, your friend Reuben (an expert chemist) says this: "Soluble metal oxides form hydroxides when dissolved in water." Using Reuben's statement, and what you already know about chemistry, predict the products of the following reaction. Be sure your chemical equation is balanced.
Answer:
The product will be potassium hydroxide.
Explanation:
When aqueous potassium oxide reacts with water it gives aqueous solution of potassium hydroxide as a product. And potassium hydroxide is a hydroxide of potassium metal with formula KOH.
According to recation , 1 mole of potassium oxide when recats with 1 mole of water to give 2 moles of potassium hydroxide.
