<h3>Answer:</h3>

              Br (Bromine)

<h3>Explanation:</h3>

Li and K,

As the electronegativity difference between Li and K is less than 1.7 therefore, ionic bond cannot form between these two metals.

Li and Fe,

The electronegativity difference is less than 1.7 so neither electron loss nor electron gaining will take place between these two metals. Therefore, there will be no ionic bond between them.

Li and Kr,

As Krypton is a noble gas and does not react due to complete octet hence the formation of KrLi is difficult. However, Krypton can make compounds like KrF₂ e.t.c. Therefore we can skip this option.

For Li and K,

                   E.N of Bromine             =   2.96

                   E.N of Lithium               =   0.98

                                                             ________

                   E.N Difference                     1.98          (Ionic)

This ionic compound is possible and is the correct option because ionic compounds are always made by metals and non metals and here the combination is perfect.

<h3>Conclusion:</h3>

                          Lithium (a metal) and form Ionic bond with Bromine (a non metal)

Determine the number of valence electrons for magnesium
12345 [234]

Answer:

Magnesium has 2 valence electrons.

Explanation:

The atomic number of magnesium is 12. This means that it has 12 protons and 12 electrons. The first electron shell can hold 2 electrons, the second can hold 8, so the third will have 2 electrons. The outermost shell of the atom has two electrons. Therefore, magnesium has 2 valence electrons.

Tell how you could distinguish between the pair of compounds by their infrared spectra: compound a ch3ch2ch2n(ch3)2 and compound
maksim [4K]

Answer:-

b. compound b will show an nh absorption while compound a will not.

Explanation:-

For compound B CH3CH2CH2NH2 there are two N-H bonds present. So it will show NH absorption.

But in compound A CH3CH2CH2N(CH3)2 there are no N-H bonds. So it will not show NH absorption.

You have been given a sample of an unknown
anastassius [24]

Answer:. an ionic compound

Explanation:

If it conducts electricity when molten, then it is an ionic compound. No covalent compound conducts electricity in molten state because their crystal lattice is not composed of ions. There are ionic solids which conduct electricity when molten but are insoluble in water such as alumina Al2O3. The solid is soluble in strong acid solutions.
