<u>Answer:</u> The correct answer is Option B.

<u>Explanation:</u>

Electronegativity is defined as the property of as element to attract the shared pair of electron towards itself. The value of electronegativity is high for non-metals because they can easily gain electrons as compared to the metals.

This value decreases as we move down the group and increases as we move across a period.

Halogens are the elements which belong to Group 17. They easily gain electrons in order to attain stability. Thus, these elements have high electronegativity values.

Alkali metals are the elements which belong to Group 1. They easily loose electrons in order to attain stability and thus have low electronegativity.

Transition elements are the elements which belong from Group 3 to Group 12. They easily loose electrons in order to attain stability and thus have low electronegativity.

Alkaline earth metals are the elements which belong to Group 2. They easily loose electrons in order to attain stability and thus have low electronegativity.

From the above information, the elements which belong o Group 1 have the lowest electronegativity values.

Hence, the correct answer is Option B.

Why are metals malleable,ductile,and good conductors
9966 [12]
The energy is transferred throughout the rest of the metal by the moving electrons. Metals are described as
malleable (can be beaten into sheets) and ductile (can be pulled out into wires). This is because of the ability of the atoms to roll over each other into new positions without breaking the metallic bond.

balandron [24]

Answer:

<em>At equilibrium, the rate of the forward, and the reverse reactions are equal.</em>

Explanation:

In an equilibrium chemical reaction, the rate of forward reaction, is equal to the rate of reverse reaction. Note that the reactions does not cease at equilibrium, but rather, the reactants are converted to product, at the same rate at which the product is also being converted into the reactants in the reaction. When chemical equilibrium is reached, a careful calculation of the value of equilibrium constant is approximately equal to 1.

NB: If the value of equilibrium constant is far far greater than 1, then the reaction will favors more of the forward reaction, and if far far less than 1, the reaction will favor more of the reverse reaction.
