Answer:
As the difference in electronegativity between two atoms decreases, the tendency for the formation of covalent bonds "increases"
Explanation:
Electronegativity being a chemical property which tells us about the tendency about the atom in order to fascinate the shared pair of the electron towards itself. It is being pretentious by atomic number and the distance as well, by the help of which the valence electrons resides from the charged nucleus. In the scale Pauling scale is used. Being the most electronegative element fluorine is counted. The more the electronegativity, the more electrons will fascinate towards itself.

Answer:
He.
Explanation:
- Graham's law states that the effusion rate is inversely proportional to the molecular weight. It means that the gas with the lowest molecular weight will have the highest effusion rate.
The molecular weights of the given gases are:
Cl₂ = 70.9 g/mol.
He = 2.0 g/mol.
O₂ = 32.0 g/mol.
Ne = 20.17 g/mol.
<em>Since He has the smallest molecular mass, so it will have the highest rate of effusion.</em>
