Answer: Option (c) is the correct answer.

Explanation:

Electronegativity is defined as the ability of an atom or element to attract the electrons from another atom towards itself.

Non-metals are the species which are electronegative in nature. Whereas metals are the species which are electropositive in nature.

For example, F, l, Br and I are group 17 elements. These are electronegative in nature but their electronegativity decreases from fluorine to I.

Whereas Li, Na, K are alkali metals and most electropositive in nature.

Similarly, Be, Mg, Ca are group 2 elements and they are also electropositive in nature. When we move from top to bottom in a group then there is a decrease in electronegativity of the non-elements.

But when we move from left to right in a period then due to decrease in size of the atoms there will be increase in electronegativity of the atoms.

Thus, we can conclude that K, Ca, Sc list of elements is arranged in order of increasing electronegativity.

2Mg + O2à MgO For this unbalanced chemical equation, what is the coefficient for oxygen when the equation is balanced? A. 1 B. 2
Vikki [24]

Answer:

The answer to your question is the letter A. 1

Explanation:

Unbalanced chemical reaction

                      Mg  +  O₂  ⇒  MgO

               Reactants    Elements    Products

                       1            Magnesium       1

                       2           Oxygen              1

Balanced chemical reaction

                      2Mg  +  O₂  ⇒  2MgO

              Reactants    Elements    Products

                       2           Magnesium       2

                       2           Oxygen             2

Conclusion

The coefficients of the balanced equation are 2, 1, 2
