Compared with the electronegativities of the elements on the left end of a particular period, the electronegativities of the elements on the right side of that same period tend to be a. lower. b. higher. c. the same. d. unpredictable.

C Higher. As you go to the right on the periodic table, the number of balance electrons increase, which means that the attraction will be higher. A total of 8 electrons is needed to complete the octet. Since F only has 7 valence electrons it will only need only one electron that will pull from a metal. That's why Floudine is te most electronegative element.

Option (B) is the correct answer.

Explanation:

When we move from left to right in a period then size of atoms decrease and electronegativity of atoms increases.

This is because as the size is decreasing along the period, the atomic number increase this means number of protons also increases along with electrons.

Since protons are positively charged and electrons are negatively charged. Thus, there will be attraction between protons and neutrons.

As a result, there will be increase in electronegativity along the period.

Hence, we can conclude that the electronegativities of the elements on the right side of that same period tend to be higher.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
