Answer:

A. iodine

C. fluorine

F. bromine

Explanation:

Ionic bonds occur mostly between metals and non-metals. Usually, a wide electronegativity difference is preferred between the two atoms. This makes one atom more desirous to gain electron and other more willing to donate electrons.

To have Zn forming  a compound in the ratio of 1 to 2, the combining power must be similar to this.

The dominant oxidation state of Zn is the is the +2 state.

The other combining atoms must have the ability to recieve the two electrons.

The halogens fit perfectly into this picture. They need just an electron to attain nobility. They are also highly electronegative. If two halogens combines with the Zn, then the ionic bond will result.

The halogens are fluorine,chlorine, bromine, iodine and astatine.

They will form these compounds:

                       ZnF₂, ZnBr₂ and ZnI₂

Which of these substances contributes to soap’s slippery texture?
kompoz [17]

Answer:

The fatty acids and glycerol contributes to soap’s slippery texture.

Explanation:

  • What we need to know is that every oil has a specific index for strength, cleaning, etc.
  • All of them are determined by the amount of certain fatty acid in the oil.
  • When we make soap, what we need to know is that oil has a special role to play in that soap.
  • So for example some of those oils are used to make bubble soap or creamy soap.
  • On the other side, there are some oils which are giving strength to soap.

Which atom’s ionization energy is greater than that of phosphorus (P)? A. Ba B. K C. As D. Cl
aalyn [17]
<h3>Answer:</h3>

                   Chlorine (Cl)

<h3>Explanation:</h3>

                           Ionization Energy is defined as, "the minimum energy required to knock out or remove the valence electron from valence shell of an atom".

Trends in Periodic table:

               <em>Along Periods:</em>

                                        Ionization Energy increases from left to right along the periods because moving from left to right in the same period the number of protons (atomic number) increases but the number of shells remain constant hence, resulting in strong nuclear interactions and electrons are more attracted to nucleus hence, requires more energy to knock them out.

               <em>Along Groups:</em>

                                        Ionization energy decreases from top to bottom along the groups because the number of shells increases and the distance between nucleus and valence electrons also increases along with increase in shielding effect provided by core electrons. Therefore, the valence electrons experience less nuclear attraction and are easily removed.

<h3>Conclusion:</h3>

                   As Barium is present down the group and to the left of periodic table, K present at the left of the periodic table, Arsenic present below Phosphorous will have less ionization energies as compared to P. Hence, only Chlorine present at the right extreme of periodic table and right to P will have greater Ionization energy.
