Answer: The given statement is true.
Explanation:
Chemical bonds are defined as the bonds formed due to interaction of electrons of two same or different atoms. Basically, these electrons are physically attracted towards each other because of which either sharing or transfer of electrons tend to take place.
For example, Cl has 7 valence electrons and sodium has 1 valence electron. In order to gain stability when both sodium and chlorine will come closer then Cl will attract one electron from sodium leading to the formation of a new compound NaCl.
Thus, we can conclude that the statement chemical bonds are physical attractions between atoms resulting from the interaction of their electrons, is true.
<u>Answer:</u> Yes, metals and non-metals forms ionic bonds.
<u>Explanation:</u>
Ionic bond is defined as the bond which is formed by complete transfer of electrons from one atom to another atom.
The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal and a non-metal.
<u>For Example:</u> Formation of sodium chloride
Sodium is a metal and is the 11th element of periodic table having electronic configuration of ![[Ne]3s^1](https://tex.z-dn.net/?f=%5BNe%5D3s%5E1)
To form
ion, this element will loose 1 electron.
Chlorine is a non-metal and is the 17th element of periodic table having electronic configuration of
.
To form
ion, this element will gain 1 electron.
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
So, the compound formed between sodium and chlorine atom is NaCl
Hence, metals and non-metals forms ionic bonds.
