<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.
Answer:
D
Explanation:
A and B are completely wrong and C is partial but D is the best option
Answer:
unit of mass = kg,g
unit of length = ft , m ,cm
time = s min hr
Answer:
2.1 x 10¹²ng
Explanation:
Mass of the calcium carbonate given is:
2.1kg
We need to take this mass to nanogram, ng.
Since :
1000g = 1kg
10⁹g = 1ng
So;
1kg = 1000 x 10⁹ = 10¹²ng
So;
2.1kg will give;
Since
1kg gives 10¹²ng
2.1kg will give 2.1 x 10¹²ng
Yes Universe grow more and more as the time pass
There is CREATOR of universe beyond it
