Answer:
Ionic or electrovalent bond
Explanation:
The electronegativity of an atom determines to what extent an atom would attract an electron towards it. So, they can form combine.
The nature of chemical bonding depends upon the difference between the electronegativity of the combining atoms.
When the electronegativity difference is
< 0.4 - forms non-polar covalent bonds
between 0.4 and 1.7 - polar covalent bonds
> 1.7 - ionic bond
Hence, when there is a large difference between the electronegativity of atoms, it forms ionic bonds.
S = ut + 0.5at^2
<span>10 = 0 + 0.5(9.81)t^2 {and if g = 10 then t^2 = 2 so t ~1.414} </span>
<span>t^2 ~ 2.04 </span>
<span>t ~ 1.43 seconds</span>
