Answer:
I think is the last one!!!! punnet square ⬜
Answer: Option (b) is the correct answer.
Explanation:
The elements which have excess or deficiency of electrons will react readily.
Atomic number of Mn is 25 and electronic configuration of
is [Ar]
. This configuration is stable.
Atomic number of Cr is 24 and electronic configuration of
is [Ar]
. This configuration is not stable.
Atomic number of Fe is 26 and electronic configuration of
is [Ar]
. This configuration is stable.
Atomic number of Cu is 29 and electronic configuration of
is [Ar]
. This configuration is not stable.
Atomic number of Al is 13 and electronic configuration of Al is
. This configuration is not stable.
Atomic number of Ba is 56 and electronic configuration of
is [Kr]
. This configuration is stable.
Atomic number of Mg is 12 and electronic configuration of
is
. This configuration is stable.
Atomic number of Sn is 50 and electronic configuration of Sn is [Kr]
. This configuration is stable.
Thus, we can conclude that out of the given options, only Fe and
reactants would lead to a spontaneous reaction as they have incomplete sub-shells. Therefore, in order to gain stability they will readily react.
<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.
